validity for - 101 application delivery fundamentals exam
Hi, I just passed f5 101 and I was wondering how long it is valid? For reasons that are not worth mentioning here, I need to switch my focus momentarily to some other technical topic. I'd like to come back and take at least the 201 exam, but I'd like to know how much time do I have? I've looked for how long is 101 available but I couldn't find any info regarding this, hence my post here. If somebody can point me in the right direction please let me know! Thank you in advance! TudorF5 Certified Practice Exams
Thinking of taking the F5 Certified 101 or 201 exams but not sure if you are ready? Ease the anxiety by taking a F5 Practice Exam! That’s what I did, and it sure helped. If you remember, back in August I attempted the 201-TMOS Administrator exam and successfully failed, missing by a few questions. I’ve been wanting to try again and had an opportunity last week but I hadn’t studied since that initial attempt at Agility. If I failed again, I’d have to wait another 45 days to give it another go. So instead, I decided to take a practice exam. Practice exams provide candidates with an accurate prediction of their performance for the live, production exams. Other than the section-level score reports, they are not intended to be used for study or learning purposes. Their entire value is based on their similarity to the production exams and their validity in predicting your performance. If you think you’re getting a sneak peek to real questions, think again. They use entirely different questions on the live exams, so unless you actually learn the underlying knowledge, 'knowing'the practice questions is completely useless and becomes waste of time. The Practice Exams are designed to mimic the real tests with 80 questions timed to 90 minutes. There are exhibits to consider, you can flag questions to review and you get instant feedback on your results. You can complete on your own device and you can ‘alt-tab’ to look up the answers if you so desire. Not that you should – defeats the purpose. While you do not get an actual score, you do get an indication if you Passed or Failed and insight (Below/Borderline/Meets) on how you did on the sections. As you can see, 4 months of not studying doomed my fate. The 201 is no fly-by and really requires daily hands on experience. If I had done well, I could have taken the real exam the following day. This way, I know exactly where I need to focus and what I need to do to finally pass the 201. They don't allow unlimited access to the practice exams and recommend using the practice exams no more than two, at most three, times as part of your preparation. Once you become familiar with the questions, the practice exam loses its value. Practice exams are delivered via their Zoomorphix Exam Studio system and only available to registered candidates. They have 101 and 201 rehearsals with 301a, 302 and 303 practice exams coming soon. If you’re preparing for a @F5Certified exam, you can review some of the F5 Certification study materials that are available. Good luck! ps
Becoming F5 Certified - BIG-IP Administrator Certification - 101 & 201 Exams
How Do I Become a certified F5 BIG-IP Administrator? There are two exam you'll need to pass to become an F5 BIG-IP Administrator; Exam 101 – Application Delivery Fundamentals Exam 201 – TMOS Administration The 101 exam is mandatory, you will not be able to jump ahead to the 201 exam, or the 300 level exams. You may not like that, but once you take it you will really appreciate why F5 did this. If you work with F5 on a daily basis you are well aware there is more to becoming an F5 expert than memorizing commands and configuring BIG-IP modules. True application delivery administrators / engineers know you need skills ranging from networking, server administration, security, to development. That is the key to what separates a good F5 admin / engineer, from someone who is only comfortable adding a VIP or modifying pool members. The 101 exam was built to asses foundation knowledge in most of those areas. Not so much on the dev side, but basic iRule concepts are indeed on the 101 blueprint. About the Author Guest author Austin Geraci is a subject matter expert in F5 Networks Technology, and has worked in the ADC space for 10+ years. When he's not working with & evangelizing F5's cutting edge technology, you can find him on the squash courts, going for a ride around Lady Bird Lake, or listening to some live music in ATX. Check out WorldTechIT to read more from Austin. Step 1 - Sign up / Register yourself in F5s Credential Management System The very first thing you are required to complete before you schedule your actual exam is sign up for the F5 Certification program in the F5s Credential Management System. Once you do that you will receive an authorization email from F5 clearing you to schedule the 101 exam. The site is relatively intuitive once you register. This will be your home-base for things like F5 provided blueprints, study guides, and certification logos you can use on your website / business cards. I should note, the study guides you will find on this site are not full blown / the only thing you will need to pass the exams. They are outlines and examples of the objective topics. They will include references to material you should be basing your studies from. On the cred mgmt site you will also find an option to publish credentials, which allows you to send a certified email with your certification credentials from the credential verification services @ PEARSON VUE - note the email comes from a slightly different domain than you may be familiar with from PEARSON - CredentialVerificationServices@pearsoncred.com. This can be a handy tool to send your official creds to potential employers, boss or maybe even tease your co-workers ;). Step 2 - Schedule your test with Pearson Vue Some people will prefer to start studying before they schedule their first exam, other will take the opportunity to light a fire under their posterior. Either way, once you're cleared to test from F5 you can go ahead and schedule your F5 101 exam at F5s Certification landing page at PEARSONS VUE. Once you're registered & logged in at the PEARSON site you will see the 101 exam under pre-approved exams, go ahead and click on it - you will then be brought to a page with the exam details and a big blue button that says "Schedule this Exam". From there you will proceed to the test center search and pick a day and time that work best for you. Give yourself ample time to prepare and review all the blueprint material. I personally like morning exams, as I feel the most fresh in the am - but somehow it seems I'm always landing an afternoon slot that works with my schedule ;). When you do take the actual exam, make sure you are rested up, fed, and stress free the day of the exam. I have a friend who actually checks himself into a hotel the day before. This might sound extreme, but if you have a big family at home, the distraction free zone might prove to be worth it. However you prep in the days before, avoid cramming - it doesn't work for these types of tests. Step 3 - Preparing for the 101 Application Delivery Fundamentals Exam It's important you fully understand what you're getting yourself into before you go gung ho and schedule your exam. Review F5s 101 – Application Delivery Fundamentals Blueprint and create a plan & time-line to pass the exam. Be realistic and take it seriously, there's nothing like blowing money on the exam for a reality check, but some of you will inevitably need that motivation ;) You can go through the blueprint and create your own study guide, or you can opt to purchase the Application Delivery Fundamentals Study Guide by Philip Jönsson & Steven Iveson. There is also a free F5 101 exam study guide put together by Eric Mitchell on university.f5.com (requires login.) What did I do? I took a good look at the blueprint, and said phh I know this stuff! I then gave some quick study to sections I haven't hit on in a while. Even though I have a good background in networking and work on F5 gear on a daily basis, I found myself pressed for time, but I did indeed pass. If you are in a similar situation, I would not underestimate the exam, take your time to prepare. I didn't have Erics guide or the paid version when I took the exam - if I were to take the exam today I would probably do all 3, shell out $9.99 for the paid version, take a look at Erics study guide, and suppliment with some of my own material. F5 101 Exam Hands-On & Tips The 101 exam wasn't designed to run you ragged with hands on questions, but hands on preparation will definitely not hurt you. If you're not working on F5s BIG-IP software everyday, I would highly recommend you set yourself up with a virtual machine and purchase a license for the F5 BIG-IP Virtual Edition. For just under $100 bucks, you can have access to practice on just about all the F5 BIG-IP modules - the Policy Enforcement (PEM) & Link Controler (LC) modules are not included. You are also limited to 10mb bandwidth, and there are some limitations with the APM module, but that's no problem for the testing you'll need it for. It was a bold move by F5, which clearly shows their commitment to building competency on their platform. You can also get a free 90 day VE trial. If you do set up a VE box, make sure you get v11.4 up and running for the 101 (not always going to be v11.4), that's what the test (at this time) is based on. Remember this is a fundamentals exam, once you go through the blueprint you will see there are a lot of topics on fundamental knowledge of Network Engineering & Application Delivery. In other words, you won't have to go crazy with hands on - but it's not going to hurt & it will help you for the 201 test. Here are some quick tips to keep in mind when taking the 101 exam: Version # The test is currently based on TMOS v11.4 Number of questins on the 101 exam There are 70 questions on v1, and 80 on v2. V2 is going live sometime in Q1 of 2015. 10 of those v2 questions are unscored Passing score You will need a ~69% to pass the exam (may change with v2) Partial Credit No, All questions are scored equally, and no partial points are awareded. Time Limit 90 Minutes (non-native English Speaking residents automatically get 30 additional minutes. Time managment Manage your time appropriately, don't dwell on hard questions - especially if you're taking v2 - the question might not even count! So answer what you know and move on. Utilize the mark question feature and review what you didn't answer at the end of the exam, the back button is your lil friend. Step 4 Preparing for the 201 TMOS Administration Exam Allright, you made it this far - you passed the 101! Give yourself a pat on the back, but don't get carried away, the fun has just started ;). In about a day from passing the 101 you should receive an official pass letter and an authorization email from F5 clearing you to schedule the 201 exam. I'll take this opportunity to mention some people have reported failing the exam at the testing center but passing when they received their email from F5. I'm not sure what the deal with that is, I only mention this so you don't lose all hope if you fail at the testing center. Again, you can go ahead and schedule the 201 exam now, or take the time to review the 201 TMOS administration blueprint and study to fully assess the time frame for the task at hand. At the time of publishing this article, the only public F5 201 study guide is the one completed by the gentleman and scholar, Eric Mitchell, also available on university.f5.com. I used this Study guide and filled in some of the lighter sections with my own -I passed the exam. I was more mindful of the time crunch this time, but I still cut it close on the limit. From discussions in study groups this is done on purpose by F5, as part of their assessment on you. F5 201 Exam Hands-On & Tips If you take a look at the 201 Blueprint you'll quickly see the topics cover actual administration of the Traffic Management Operating System (TMOS). You will absolutely need hands on experience to pass this exam. If you're not working with the gear everyday, and you didn't take my advice to setup that BIG-IP VE for the 101- Now would be a good time. Let me be clear, you will not pass this exam unless you have experience working on BIG-IP Software and in particular the Local Traffic Manager (LTM) module. Keep in mind this test is geared to measure your "administration" skills, particularly from the GUI. The 300 level exams will test more of your working knowledge of the CLI. With that in mind, don't rule out all of the CLI - pay attention to the blueprint and don't put 100% faith in someone elses study guide. Here are some quick tips to keep in mind when taking the 201 exam: Version # The test is currently based on TMOS v11.1 Number of questions on the 201 exam 80 with 10 of those questions being unscored (F5 testing out new questions) Passing score You will need a ~69% to pass the exam Partial Credit No, All questions are scored equally, and no partial points are awarded. Time Limit 90 Minutes (non-native English Speaking residents automatically get 30 additional minutes. Time management You will need to work efficiently, and effectively - manage your time appropriately!! I can't harp on this enough, I almost ran out of time - it came right down to the wire for me! Remember, only 70 of the 80 answers count - answer what you are confident in, then move on. Once you've answered all you know do some quick math of reaming time divided by remaining questions and try to stick to that limit when going back to them. BIG-IP Administrator Recertification You may be wondering how do I recertify my BIG-IP Administrator Certification? First, you should know your certification is good for 2 years from the time you became F5 certified. As long as you are within the 2 years, you can take the 201 exam again, or achieve F5 CTS status. Which means passing the 302, 303, 304, or 301A & B exams. To clarify further, you need to pass both 301A & B, one won't cut it, opposed to the other 300 level exams that only consist of one exam. If you let your two years pass, you will indeed need to retake the 101 exam. Make sure you stay on top of your time-line, and create a plan that leaves you plenty of time before the 2 year expiration. What's next? Hopefully by this point you've received the victorious pass letter from F5 with the subject line "You have been certified as an F5 Certified BIG-IP Administrator!". Take some time to celebrate and acknowledge your accomplishment - you're now officially an F5 Certified BIG-IP Administrator ;) Don't stop there, if you log into F5s Credential Management System you will see you now have access to all the 300 level Certified Technology Specialist (CTS) blueprint & study guide. Note the 301b exam will only be available for you to take with PEARSON after you pass the 301a exam. Some people opt to conquer the 301a/b first, since they just finished the 201 exam, others take a break and hit one of the other exams. There is no right or wrong here, it's all a mater of preference. Which path are you going to choose? Here is a list of all the 300 level F5 CTS LTM Exams Exam 301a – LTM Specialist: Architect, Setup and Deploy Exam 301b – LTM Specialist: Maintain and Troubleshoot F5 CTS GTM Exams Exam 302 – GTM Specialist F5 CTS ASM Exams Exam 303 – ASM Specialist F5 CTS APM Exams Exam 304 – APM Specialist What has your experience been like with the F5 Certification program? Any tips or insights of your own you'd like to share? Maybe a question or two about the certification process? (NOT an actual cerfication question. Sharing certification exam details can result in loss of certification and expulsion from the program for life!)Well jump on in and comment below!F5 Certifications Mega Meta Series: Congratulations, you have passed!
In this series of articles, I have gone into the details of how the exams are developed (...as far as I know at least), and how I think you can improve your chances of passing them. And now that you have,enjoy! Enjoy the rest of the day, and soak up the rays of a job well done! Second, party! Third, tell everyone about it! Especially us techies aren’t good at boasting about our achievements, but passing these F5 exams, I would definitely call an achievement. Guest Author: Alex Tijhuis An evangelist for anything software designed and security, and a self-described massive network geek, Alex is an F5 trainer and consultant at ABCT.net. While certified and highly skilled and interested in all things F5, he's just as happy pulling cables in a data center and designing scalable systems as he is messing around with the latest cool kids toys our fine industry has to offer. Once the celebrations are over, you should also receive your mail from F5 to confirm that they have ratified your results – assuming you haven’t tried to do something nasty. With this, you can then look online to check your passing score, which will give you an indication of how close you were (https://certification.f5.com/). Keep in mind the MQC (Minimally Qualified Candidate) metric that F5 uses – no matter if you have barely passed or easily passed, you have passed! And when it comes to telling people about it – they really don’t care. As another wise colleague once said; “boast about the fact that you made it, not about how closely you almost didn’t pass.” Badges are also a useful feature. On the same site, you will be able to find them and you can show them to the world! Most exams nowadays have it, but if anyone ever asks you to confirm that you indeed have this exam, you can send them the badge, which links to the F5 page that confirms that this certification is still valid. Too many people have been boasting about certificates that they don’t actually have, or are no longer valid. This validation system is a great way to confirm from the source that you still have the accreditation. What’s next? Not to say you have to change your job, but as we have now seen, these certifications are worth their time and money and if you were thinking about looking for something better, now might be the right time to do it! Of course, good managers will recognise potential before it leaves the building and will happily give you the work (and hopefully pay rise) that comes with it. In my case, the F5 certifications helped me to leave my 24/7 helpdesk job and move into presales, then training, and nowadays running my own business. Even if you don’t immediately want to change or take on the new skills, you can still take pride in the knowledge that you know your stuff. And why not take this further? Which exam are you looking at next? I’m aware that there’s lots of other exams to be had, but if you are enjoying these, why not try some more? Each 300 level exam gives you access to more opportunities and options. Going for a 400-level one will only expand on that, with the added bonus that you can do less exams every time when renewal comes up. Talking about renewals; in order to keep your certification valid, you need to renew them roughly every two years. Though with the recent lockdowns, F5 has extended the validity of most certifications so that nobody would be uncertified due to not being able to sit the exam. Dr. Ken Clarifies... F5 has not “extended the validity of most certifications so that nobody would be uncertified due to not being able to sit the exam”. We extended the “grace period”. The difference is subtle, but it is critical. Certifications expiring during the pandemic will still expire and, once expired, they cannot be used to satisfy the prerequisites of a higher-level exam/certification. Extending the grace period simply gives candidates more time to renew those certifications without having to go all the way back to exam 101. ALSO, taking a higher-level “exam” will not renew any prerequisite certifications. Achieving a higher-level “certification” will. Again, it is subtle, but can be important. Passing exam 302 confers the F5-CTS, BIG-IP DNS certification, which in turn will renew/extend the prerequisite F5-CA, BIG-IP; HOWEVER, taking and passing exam 301a does not result in a certification and, thus, does not renew/extend the F5-CA (it makes you eligible for 301b, which if passed then confers a certification and renews the prerequisites). Personally I find the 2-year renewal period a bit short, but I get why they do it. The technology changes so rapidly that in order to keep up, you should keep yourself up-to-date as well. Funny enough, when it comes to recertification, I have found that it takes much less time to prepare for them than I did for the original exams. This year I recertified my 402 and 202. For neither of them did I actually spend more than half a day on preparation – maybe a day at most. Remember, you don’t have to know the facts, you need to understand the scenarios and the rough F5 environment. As long as you keep getting exposed to F5 systems, recertification shouldn’t be too difficult. Alternatively, when it comes to recertification time, why not go for that higher-level one? Depending on which exam you have done, you can do a higher-level exam the next time around and it will automatically renew your previous exams (check the F5 exam policies for an exact overview of possibilities - https://support.f5.com/csp/article/K90101564 Again, as long as you are being exposed to F5 systems, you will probably find this easier than you might think! Where to next? If you ever thought about moving to a different place or country, these exams can also help for sure! Because of their international recognition, and a chronic shortage of good F5 engineers worldwide, there is always a job going somewhere that will interest you! Having lived in many different places myself, I can honestly say it’s the best way to expand your knowledge and understanding – brave the unknown! Get out of your comfort zone, pick up new things and try new ideas. If anything, use the certifications as a proof to yourself that you apparently DO know something. Even though we techies often don’t value ourselves that highly, clearly we have done well – so trying something new might not be such a bad thing after all. The trolls (ahem) of the exam development group have tried to make you fail, but in the face of danger, you laughed and came out victorious! Congrats and whatever you try next – go for it! Dr. Ken Says... I’d only add that, having been a practicing engineer who achieved a lot of certifications, I really wanted our program to be something people could be proud of. It is not easy and achieving it will likely require more work and effort than most of the any other certifications you may have. Most of the “complaints” I get basically all say the same thing, “it’s too difficult to get your certifications, why can’t you make it easy like everyone else?” To them I say, “why would you want something that anyone else can get?” Achieving an F5 certifications, especially the F5-CTS or F5-CSE certifications, is really an achievement. You should be proud of your accomplishments; I know we are.F5 Certifications Mega Meta Series: Congratulations, you have failed!
In this series of articles, I will go into the details of how the exams are developed (...as far as I know at least), and how I think you can improve your chances of passing them.Everyone fails an exam every now and then - my exam history is a definite testament to that. If you never fail an exam, I suspect you spend more time on preparing for an exam than you really should. Let’s have a look at some of things you can do so that it doesn’t happen too often though. Guest Author: Alex Tijhuis An evangelist for anything software designed and security, and a self-described massive network geek, Alex is an F5 trainer and consultant at ABCT.net. While certified and highly skilled and interested in all things F5, he's just as happy pulling cables in a data center and designing scalable systems as he is messing around with the latest cool kids toys our fine industry has to offer. Let’s try again! F5’s exam policy (https://support.f5.com/csp/article/K90101564) stipulates when you are allowed to retake exams again; wait 15 days after first fail, 30 days after second, 45 after third and a year after fourth. This has been done to ensure that nobody will keep doing the exam in the hope of memorizing questions and passing by accident. I quite agree with that. Still, everyone can have a bad day, and everyone will fail every now and then – as I said, my own exam history is a perfect example of that. But when you fail, don’t let that keep you from trying again! Here is how I look at the number of tries: First time failed? Meh, nobody cares, everyone fails now and then. Brush up on what you think may be missing and see if you can find some other sources of material. Second time failed? Not to worry, hope you have recognised the areas that you need to focus on and you better rebuild some of the scenarios in your lab or find some more study material for those areas. Third time failed? Okay, you really need to straighten up now and prove that you are actually trying! Fourth fail? You may want to rethink your career plans. I will leave it up to you to decide when is a good time to try again, but don’t put it off too far, or it will be “conveniently” forgotten about. If it was worth doing it a first time, it’s worth trying again. “It is better to have tried and failed, than to have never tried at all” Wait, is that how that saying goes? But it is right. I’m not saying waste your tries, but don’t hold back either, failing isn’t such a bad thing! Learn from your mistakes Although your initial result at the exam centre doesn’t tell you your score, once the results have been uploaded to F5, you should find your exam score in the Exam History section of the Certification portal (https://certification.f5.com/). I believe that nowadays the exam score runs from 100-350 points with 245 (or in hex…F5!) being the passing mark. It’s not much consolation, but knowing how close you are to the passing mark, gives you an indication of how much extra work you should be putting into preparing for the next time. If you were close to the pass mark, you should have a good feeling of which questions you were struggling with and what topics you didn’t know enough about. If you can’t remember, it's likely that everything was difficult and you are best off starting from the beginning again. Remember, these exams are designed to distinguish between those who can and those who cannot. So if you were just “wingin’ it”, you'll get beaten up by the exam. Go back to the blueprint and see if you can match up those topics you were struggling with. That’s your starting point for the next phase. What to change? When you are going back to your study material to find out what you have missed, don’t stick with just the same material. My daughter being a prime example who keeps doing the same thing and expecting a different outcome. “But I’m trying!” No you’re not, you are just too stubborn to stand back for a few seconds and think about what you are trying to do, and changing it if needed – oh how I recognise my younger self in her... Just like the hackers that are trying to attack your F5 really. If they notice that an attack doesn’t work, they will change their approach – no point in trying something that doesn’t work. So should you change tack too. The material you may be using might not be of the level you require. Maybe you are just not understanding what the material is trying say, or the material is simply not covering the topics that you need. Find some other resources to study, ask some other people for help and build out some more scenarios in your lab. If you do this right, I am certain that there will be a few times that you say “aaahhh, of course, that’s what I missed” when you go through it. Of course there is no guarantee that you will get the same questions again next time around, but you have at least covered off yet another gap in your knowledge, and have gone on to improve yourself – and isn’t that what the whole certification program is for anyway? A few years ago, I coached someone for the 401 exam. He had a great background in networking and security, but limited knowledge of F5’s. He managed to pass most of the 300-level exams in a few months’ time! By the time we met, he was ready for the 401. After spending a day with him talking about a variety of topics, and letting him lab up various scenarios for a week, he sat the 401 exam…. And failed. Meh, no real problem, we had another chat afterwards, discussed some of the topics he recognised he was struggling with, spend another week in the lab, …and passed! Well done and well deserved for sure! Before you ask, no, I do not suspect any foul play. I have never seen such a feat repeated again and am still in awe of this guy’s brilliance. (If you read this, you know who you are...) For most of us, that's not the case though and we actually have to make an effort... ;) Long story short, for me that was a perfect example of someone used to passing, but still failing from time to time. Meh, it happens, brush yourself off, learn from your mistakes, try again and succeed! Dr. Ken Says... Many will know that I spent many years pursuing certifications when I worked as an engineer. In the many, many exams I took, I only ever failed two exams. The first one was Novell 4.0 print services (yes, that dates me a bit), which I took a second time and passed. The other was F5’s 201: TMOS Administration exam. For context, I have been with F5 for over 21-years now and my original role was as a field systems/sales engineer: I sold, designed, installed, and provided support on F5 systems around the globe. My second role was as one of the first “Security Architects” at F5, working with TrafficShield and FirePass (again, dating me a bit if you recognize the product names). I was, I believe anyway, a fairly well-respected F5 engineer. The point being … I’m no novice when it comes to F5 equipment. So, why did I fail 201? I failed 201 because it I took it nearly a decade after I quit working as a full-time F5 engineer. Not only had many things changed, but knowledge and skill are perishable; they decline over time. While I didn’t fail 201 by much (and I didn’t study for it at all), the assessment correctly determined that I was no longer capable of doing the job. Yes, it hurt my ego a little, but I’ll have to admit it was a fair assessment. I wouldn’t hire me to do the job anymore either. As the author intimates, failing an exam doesn’t make you a failure, it just means you need to work a bit more to pass the exam; it’s not personal. In case you’re wondering, no I haven’t retaken exam 201. Primarily, it is because I don’t do the job and having the F5-CA, BIG-IP doesn’t have much value in my current role. At the same time, I will admit that I like to tell this story because it underscores the validity of the assessment, and why we have some of the policies we have. 2-year renewal; knowledge is perishable. Complain to me that you can’t pass an exam even though you’ve worked with F5 gear for 10-years; you and me both!!

In this series of articles, I will go into the details of how the exams are developed (...as far as I know at least), and how I think you can improve your chances of passing them.One of the biggest killers in F5 exams is the time pressure. Most of the ones that I’ve done, I’ve ran out of time, and no, not just the 400 levels. I believe that I had the same problem when recertifying my 202 recently. Why is that? Well, apart from me maybe just not being as good at this stuff as some of you, I do believe it has something to do with what the exam is testing; can you figure out real life stuff, rather than regurgitating facts. Guest Author: Alex Tijhuis An evangelist for anything software designed and security, and a self-described massive network geek, Alex is an F5 trainer and consultant at ABCT.net. While certified and highly skilled and interested in all things F5, he's just as happy pulling cables in a data center and designing scalable systems as he is messing around with the latest cool kids toys our fine industry has to offer. As mentioned in my previous article; the exams are scenario-based rather than knowledge-based. With knowledge-based questions, it’s easy; you know it or you don’t. No matter how much time you are given, it won’t influence your answer. With scenario-based questions, it’s quite the opposite; if I give you enough time, you should be able to figure most of the stuff out. The difference between a good engineer and a bad one, is not that the good engineer knows more. For me, a good engineer can quickly spot where a problem MAY lie in a complex environment, and how to start testing for things to get to the bottom of problems quickly. Nobody walks in to a problem and just “knows” what the answer is. Okay, unless they are the ones that have caused the problem to begin with, but maybe we’ll leave that one for another day. So, in order to really understand the stuff you are dealing with on the exams, you NEED a lab. The 101 maybe not yet, and you could wing it through the 200 level exam(s) without it, but the 300-level and upwards, you don’t really have a choice. Having hands-on experience immediately helps you recognise scenarios, certain features and their behaviour as well as general experience of how things work in real life. What to put in a lab? An F5… or 2. I’ve got about 40 F5’s, together with a bunch of BigIQ’s, but I wouldn’t recommend that to the average user. A physical F5 is not needed and is very noisy, so no point in going for those (…unless your lovely boss gives you access to them of course!) If you have the capacity to run a few systems on your laptop, great, but keep in mind that you will need at least a few servers running at a time, which often overwhelms all but the best of laptops. Instead, have a look around eBay and the likes for some cheap second-hand servers. There are often all kinds of devices lying around with a wide range of specs and at various prices. If you are in the UK/EU, I love these guys: https://www.bargainhardware.co.uk/* If you are lucky, you can find some high-spec silent servers if peace and quiet is a must for you, but even some basic servers are often good enough. I am running all my kit on a bunch of second-hand cloud servers that I bought for about 500 dollars each – and that included 128GB ram and 16 CPU cores! Finally, grab a bunch of el-cheapo hard drives from eBay* and you are all sorted! I’m not saying it’s cheap, but having a decent lab environment doesn’t have to cost the earth. As a hypervisor, you can basically take whatever you prefer, but I’m a big fan of Proxmox*, a free hypervisor that is very easy to set up and highly scalable Of course, if you like their work, buying a support license would always be nice! Once that’s up-and-running, it’s time to start building VM’s! For anyone with a partner F5 account, there is the vLab section on the F5 Downloads page. For anyone who works at an F5 partner, but doesn’t see the vLab section at the bottom of the page, have a chat with your account manager of presales contact. This page contains the images of some backend servers, as well as a big package of demos and exercise guides – gold dust really! For anyone else, I’d recommend just building a server yourself using an Ubuntu image, or if you have gone for Proxmox, you can download preconfigured webserver containers in a few minutes. The only thing you then need, are a few F5 boxes. You can get lab licenses for about 100-200 dollars (a great investment), or you can request trial licenses via https://www.f5.com/trials - so no reason to not have them. With these licenses, you can download the F5 images from the Downloads page and you should be ready to go! Here is a trick by the way for getting a few lab licenses paid for by your boss; “Everybody has a lab, some people are lucky enough to have a lab that’s separate from their live environment.” – I can’t remember where I heard this quote first, but it sure will make your boss shiver and pay up quickly! Even the process of building the lab is already a good exercise for the exam to be honest. It will bring back your networking skills, your troubleshooting skills when things eventually go wrong and your cloud skills of course! When you have a good setup, I can also recommend taking a few snapshots of your systems, so you can always rollback to a working state of your systems – it’s pretty painful if you have been playing with the kit, have got it all stuck and have no clue on how to recover from it (yet). Being able to roll back to a working state will save you lots of time and frustration. What to do now? …whatever you want, really. The blueprint (see a previous article) should give you some indications on what you still need to learn about certain topics. Also see if you can indeed find that package of lab guides under the vLab section of the Downloads page. If you still have any old manuals from training courses, that’s also perfect. Or last but not least, have a look here: https://clouddocs.f5.com/training/community/ There is a treasure trove of good lab exercises available. Software upgrades are also a good one to practise in the lab, and how to do this in clustered setups, with different modules and different upgrade paths. Okay, not necessarily all required for the exams, but still something that may come in very handy next time you need to do an upgrade in your live environment. Talking about software versions; every exam is linked to a specific version of software (the blueprint will tell you what version it is based on), but to be honest, don’t worry too much about it. The vast majority of questions are version-agnostic, so there shouldn’t be any questions that ask you about a specific command structure that only is available in very specific versions of software. But since they HAVE TO decide on a software version that is valid for all questions, they normally pick the one that is leading at that moment. As a last closing thought, you may now wonder that, if it is so important to have a lab for the exams, then why are all exams multiple-choice and is there no lab-based exam? I was curious about that myself at first, until it became clear to me that these multiple-choice questions ARE testing your lab skills because of their scenario-based questions. On top of that, it was explained to me that if F5 were to have lab-based exams, there would only be a few locations worldwide where this would be possible, and likely at an increased cost. This negates one of the principles behind the F5 exam program; anyone worldwide with the right skills, should be able to sit and pass an exam irrespective of your background or financial means. Something I fully agree with – F5 to all! Dr. Ken Says... This article approaches one of the topics near and dear to my academic research. It is all about the difference between knowing “what” (facts and bits of knowledge), and knowing “how” (how all those pieces fit together into a whole). As the author has stated numerous times, you can get “what” from Google, but that doesn’t mean you know “how” to use that knowledge. While each person requires a different amount of experience to develop expert know-how, very few will ever get this simply from reading a book; you have to practice implementing that knowledge before your brain transforms it into a highly efficient “mental model” of how it all fits together. Once that is done, you have become an expert and will approach problem solving in an entirely new way. To wit, the author mentions the dissonance between having lab skills but using multiple-choice questions to test that knowledge/skill. There is no disconnect here. Our questions are designed to evaluate a candidate’s mental model, not whether they can type fast or manipulate a GUI. It is just as simple, and more cost effective, to ask questions that determine if a candidate has done the work, than design an environment to test them doing it. One issue I have with practical exams is they not only test what you “know”, but they expect you to implement that knowledge the way we would, rather than being open to novel or innovative solutions. As such, they inadvertently limit what might be “correct”, simply because it is based on our perspective rather than being open to equally correct solutions that are accomplished in new and interesting ways. The goal should always be to determine whether the individual has the knowledge and the ability to implement that knowledge, not whether they implement it solely the way we would. It’s nuanced, but it is important. *Disclaimer; I have no affiliation with any of the sites/products I mention in this post. I’m happy with them at the time of writing, but things can change of course. If you like them, great! If you don’t, great!F5 Certifications Mega Meta Series: The art of knowing what you need to know
In this series of articles, I will go into the details of how the exams are developed (...as far as I know at least), and how I think you can improve your chances of passing them. With F5’s exams being focused on what you can do in real life, rather than what you know in theory, it makes it difficult to know what exactly you need to know for the exams. Techies don’t like that – we are like binary; we know it or we don’t. We’re not good at blagging (cheeky British term for obtaining through persuasion) our way through a conversation about something we don’t know, so why should exams be any different. Unfortunately, real life doesn't work like that, and neither should exams. This can therefore easily become a stumbling block when preparing for the F5 exams; “I don’t feel I know everything I need to know, so therefore I’m not going for the exam yet.” Guest Author: Alex Tijhuis An evangelist for anything software designed and security, and a self-described massive network geek, Alex is an F5 trainer and consultant at ABCT.net. While certified and highly skilled and interested in all things F5, he's just as happy pulling cables in a data center and designing scalable systems as he is messing around with the latest cool kids toys our fine industry has to offer. In this article (part five of eight), I hope to give you some hints and tips on how to find the right information. Everyone has their own ideas on how to work through the material though and I am under no illusion that my way is the best way – whatever works for you, great! Step 1: Blueprint K29900360. The one document to rule them all! A simple document, but oh so powerful! These are the topics that you need to know about and this is the document that the exam developers use to come up with questions (check out a recent article about that if interested). So, think of yourself sitting in the pub with some of your F5 friends and you start talking about these topics; what would you talk about, what could you ask each other? Who knows, see it as a highly specific F5 pub quiz! How simple it may sound, that will probably be the things that you would need to know about Then, looking back on the study guide, the more I already know about a certain topic on the blueprint, the less time I will spend on studying for it. Also remember that the vast majority of questions are about testing if you know the technology and how to apply it in real time, not whether you can remember facts – Google is much better at that! So don’t worry too much about remembering facts, spend more time at playing with the kit! (see our upcoming article for more about that) Step 2: Training and Research If you don’t know what a topic in the blueprint means, go to Google! (other search engines are available – I’m sure Yahoo, Bing or AltaVista may still work…) Simply get a better understanding of what a protocol or function means. Protocol-wise, I’m a big fan of Wikipedia. F5 has a variety of repositories available as well for all kinds of information; Clouddocs,AskF5, DevCentral. – get familiar with them and use them. This is also a good moment to think about training courses, if you haven’t done so already. Although the F5 training courses don’t specifically focus on the exams, they do cover a large variety of topics from the products and give you the chance to play with the kit. Most F5 trainers are also very knowledgeable about their products - they must have passed the respective 300-level exam to be allowed to deliver it after all, so feel free to ask us about it. Step 3: Expand your knowledge You will learn more than you have to for the exams – get over it. Yes, if exam is based on a book, you know exactly what you need to learn and what not. Because we don’t, and we want to make sure that we are covered, you will learn more than you have to. Is that such a bad thing? It wouldn’t be the first time that I get to a consultancy a few weeks after I’ve learned something new and they ask me if I’ve got experience with that specific topic. “Ahyes, sure! I’ve just done a project for this a few weeks ago!” They don’t necessarily have to know that it was a project in my own lab, as long as I understand and have experience with it. If anything, it shows the power of the exam; you expand your knowledge and improve your overall worth! So don’t be afraid to take some detours from the blueprint now and then when you are studying; a lot of that knowledge will come back at some point. If not to better understand the material for this exam, then at least for whatever you will do afterwards – maybe even the next exam! Step 4: Study guides Read the study guides that are available; f5books.eu are supposedly pretty good! They were developed after I’ve finished my 101 and 201, so haven’t used them myself, but have heard great things about them. Step 5: Blueprints Revisited See if the topics make more sense now. If you haven’t done so already, read the example questions that are showing on each section. If anything, it’s a form of cheating to already get these questions; use them! These example questions should be fully understood by now and you should know what technologies they are talking about and how this works with F5. If unsure, build a lab scenario that contains this information. When reading these example questions, you should also know what other technologies are related to this. For example, something that may pop up in an APM exam; understand how the F5 works with AD. Well, that tells me that I need to know the basics of AD, how the F5 works with AD, what troubleshooting tools are available for it and how it normally functions. Besides that, I can imagine that questions about related technologies such as LDAP, Radius and the likes can also be expected. Just now typing in “f5 apm ad” in Google already gives me a nice list of the most common ways to configure and troubleshoot this on the first page. Brilliant! That is my study guide sorted for the next half hour. Once you start reading stuff that either clearly hasn’t got anything to do with it, or you start to read things that you have already read, you are done for now on that topic! Step 6: Shortlist Make a list of any topics that still elude you. There are likely to be some topics that you simply don’t know where to start, or that you cannot find any good resources for. In those cases, Google and the likes are less likely to help you. Speak to colleagues, speak to consultants, trainers, presales, whoever you can find that you can talk to about it some more. It is very likely that you have simply thought of a topic the wrong way around, or have misinterpreted what it means. Someone that knows the technology can explain it to you in a different way, and all of a sudden, it may just click! They can also often give you some information that you simply hadn’t thought about yet, or can fill in other gaps. Don’t be afraid to ask. Even though I have been working with networking and security for over 10 years and I’m supposedly an expert in this area, about 25% of my time still goes on training; reading articles, joining webinars, training sessions and building scenarios – it never ends. The more I can learn from other people, the better! The only idiot here is the person that thinks they know everything. At this late stage, people often start looking for exam dumps. An honest warning; don’t. Not only are they likely to be either old exams, practice exams or just nonsense questions, you are also likely to get the wrong information because of it. Just because someone somewhere has said that for this question, this must be the right answer, it doesn’t mean it’s true. Ah, the good old days when information on the internet could be trusted. Always check for yourself and know your stuff. Better still, stay away from exam dumps altogether as they negate the effectiveness of any exam and degrade the quality of your hard-earned certificates. In addition, F5 spends quite a bit of effort on tracking unsavoury behaviour by test takers and the like (for good reason!) and I’d hate for anyone to be barred from the program because you got a bit lazy. Step 7: Relax Because of the scenario-based nature of the questions, people tend to do quite well on the exam or pretty badly. Which if I’m correct, should translate in a better spread of the overall exam results. Combine this with the knowledge that you can’t really cheat on the exam and that the exam doesn’t have to trick you to test your knowledge, and you will find that the pass mark for F5 exams are also be reasonably low. If you get a few things wrong, no worries – that’s part of the process. If you forget some protocols during the day, meh, you’ll be fine. So, get preparing… As long as you’ve done your due-diligence beforehand and tried your best to cover all topics, you’ll do fine during the exam as well. Good luck! Dr. Ken Says... In regard to the “examples” given on the blueprints, it is important that candidates understand this is not an exhaustive list of the knowledge, they are simply what they say they are: examples. If, after failing the exam, you come back to me and say, “such and such wasn’t on the blueprint, but it was on the exam”, you are: a) incorrect, because the blueprints are constantly consulted and verified by numerous experts using a rigorous process while the exam is being developed; and, b) not qualified and the exam results correctly reflected that. I really hate to say it, but feedback on the exams, especially in regard to the validity/veracity of the questions, doesn’t really mean much if you have just failed the exam. I know we all would prefer for someone else to be at fault, but if you don’t know the material enough to pass the exam, then you don’t know the material enough to provide a qualified review of the exam. That being said, if you pass the exam but still think there are issues with a question: tell us. We are not perfect, but it is not from a lack of trying.F5 Certifications Mega Meta Series: The cool side of the exam development process
In this series of articles, I will go into the details of how the exams are developed (...as far as I know at least), and how I think you can improve your chances of passing them. In this article (part four of eight), I will share some insights in how they (F5) come up with the exam questions and how to use this to your advantage. Guest Author: Alex Tijhuis An evangelist for anything software designed and security, and a self-described massive network geek, Alex is an F5 trainer and consultant at ABCT.net. While certified and highly skilled and interested in all things F5, he's just as happy pulling cables in a data center and designing scalable systems as he is messing around with the latest cool kids toys our fine industry has to offer. Over the years, I’ve been lucky enough to have been able to participate in the development of some of the F5 exams and get an insight in the workings of them. My top tip; if you ever get the chance to help with the exam development process – I would highly recommend it! One of the strong points of the F5 exams is that they are developed by a bunch of industry experts, rather than “some idiot with a book”. I’ve seen many exam questions myself over the years that are asking for such obscure knowledge that the only way to answer it correctly is to have read the exact book that the question comes from. What a waste… You have just proven that someone can read a book! (and to be honest, in real life you’ve got Google to tell you that stuff anyway) Having a bunch of people from around the world work together and come up with questions makes for a much more varied and scenario-based experience. Think about developers, consultants, support engineers and all those. They are speaking from their own experiences when writing questions, and if you ever find a question that thinly-veiled asks how “an F5 engineer has misconfigured something, what may have caused this” – you bet that that person was speaking from their own experience… Once someone has come up with a good question, it gets shown to the rest of the group; who of you can answer this question? There are normally about 10-15 people in a room, the facilitator would expect that at least half to three-quarters of all people should be able to spot the right answer. If everybody can quickly guess the right answer, it’s clearly too easy, if nobody can spot the right answer, it’s clearly too hard. It’s a first test to check a question’s validity, but a pretty good one in my eyes! Not that this is the whole process – not by a long shot! (and I’m sure I will get beaten up for making it sound so simple…) After this, questions first go into a beta exam program, all kinds of funky data analysis will be done on it and any comments from real test-takers assessed, before it may actually make it into the real exam. So if a question makes it to the real exam, you can be pretty certain that it makes sense and they are not trying to catch you out! Saying that, if you don’t agree with questions during an exam, feel free to leave comments. Every question has a comments field, so feel free to use it and they do read them. Unfortunately, your exam timer does not stop when writing comments, so be quick. I believe in Beta exams you get an extra ten minutes or so afterwards to fill in comments. This brings me to the Practice Exam. This is a facility that is available for you when you sign up to the exam certification process. Something like 25 dollars for a go, and a nice facility to have available. Personally, I’m not a big fan of it, but it does have its place; if you want to get a feel for whether you are ready for the real thing, and want to get an idea of what the exam actually looks like, feel free to give it a go. As you will likely get the same set of questions (none of which are on the real exam), there is also no point in doing it more than once really. You just start to remember the questions, instead of the topics. There are also some no-no’s when it comes to writing the question, the correct answer and the “distractors” – a cool term for the wrong answers. Such as: Questions are not meant to catch you out. If an answer looks like the right one, it probably is. If you have two or more answers that look pretty good to you (and you only need one), then you probably will have missed something, rather than the exam trying to play a trick on you. Someone who just walks in with no knowledge of the exam, should NOT be able to guess the right answer. For example; “From what direction does the wind blow?” A: North, B: South, C: West, D: It depends on the weather of that moment.” In other words, is the question idiot proof? The distractors can NOT be correct in certain cases. It needs to be clear from the question that only one answer can be correct. Don’t make the question overly complex and don’t use double negatives. The exam is to test your F5 knowledge, not to test if someone can read. In fact, with the exam being taken worldwide, the simpler the language used, the better. And remember, simple to read questions doesn’t mean a simple question to answer - “How many stars are there in the Universe?” F5 works with a measurement called a Minimally Qualified Candidate (MQC), which means a person who is JUST competent enough to not be fired. They should be able to pass the exam. The exam is not checking if you are the best in your field. As such, questions will not be checking if you know about this obscure knowledge that you only learned on page 275 of the book, or which you must have seen once while working in the dark pits of a datacentre during a blackout. F5 has something called the Wheel of Validity (it almost sounds like a game show!) which they use during the exam development process, and always hold it against what they want to really test. Starting with the subject of the exam this will turn into the blueprint, an assessment of how often these topics are actually popping up in real life, and followed by the questions per category. Even the number of questions per category being dependent on the importance of a category. See it as a risk assessment. If you normally do a certain F5 task only once a year, and if it goes wrong, nobody cares, it’s clearly not THAT important to have it right. Whereas if you have a job to do every week that MUST be done right, otherwise the place burns down, you better know what you are doing! The latter subject will therefore result into more questions. Many moons ago, when I had a quick chat with them, I mentioned that I was surprised to get quite a number of questions in my 201 exam about raising a support ticket. As it turned out – at least back then, that it is something that many people need to do “regularly” and it often goes wrong! Apparently raising a priority 1 call in the middle of the night to sort out a minor lab issue is not the nice thing to do. …but I digress. If you want to know more about what’s going in to the exam development process, there are a few really good videos / interviews with the brains behind the exam process on the DevCentral YouTube channel, such as the one embedded below – it shows you how much work goes into delivering a few lines of text on your screen while you are sitting there and sweating over them. Dr. Ken Says... There’s a lot in this post; and, while, yes from my perspective it is extremely simplified, it does capture the gist of how we put every effort into making the exams do one thing: determine if someone is minimally qualified or not. That is the only goal. I did want to clarify two things: the minimally qualified candidate (MQC), and the value of practice exams. MQC: This is not an F5 concept, but a standard concept in psychometric assessment development; and, while it sounds a bit incongruent or backwards, it is extremely important. Defining the MQC means detailing, exactly, how much knowledge we require before we are confident to allow the individual to do something. It is drawing a line in the sand saying, “if you know, at least this much, then we will trust you to do the job.” There are thousands, or millions, of minimally qualified airline pilots, brain surgeons, teachers, etc. practicing their professions today. It is really about simply defining the line between feeling confident you can do the job or not. This is also why our exams are pass/fail: you either make the mark or you don’t. We don’t actually care if you know more than the MQC, we just need to know whether you know enough to be one. Practice Exams: I know practice exams are somewhat of a contentious topic, but I believe that is because most people only know them in the way they have been used for many years: a list of questions that people study and review as a “learning” tool. Our practice exams are not designed for that. Our practice exams are built using the same process as our production (i.e. “real”) exams; in fact, we could easily use the practice exam for the real exam as it is equated (i.e., “identical” to the real exams in terms of number of questions, construction, and difficulty) to the real exams. The only difference is that it does not have the same questions. The value of this is that candidates taking the practice exam can get the same information (passing/failing, which sections they need to work on, same time constraints, understanding the style of questions, etc.) all without having the cost of taking the real exam and without it affecting your retake status. This is all extremely valuable, and I’ve known many a candidate who has just taken the real exam (from many vendors) just to get this information. The one caveat, as pointed out in the article, is the value of the practice exam diminishes each time you take it as there is only one set of practice exam questions. The more times you take the practice exam, the less the results will reflect your real exam performance. For that reason, we suggest using the practice exam only two (at most three) times; after that, the results will simply tell you how well you know the questions, rather than the material underneath.
