EmployeeVery good Alex, and to the point. I have failed one F5 exam since I joined F5, and it was APM. Reason I failed the 1st attempt was I was overconfident. Didn't study and I thought that what I knew was enough. Big mistake. It wasn't. I believe that's a mistake most people make when attempting the 101 exam. I Have two CCIE friends who failed the 101 more than once. And the reason is the same: Overconfidence. They didn't study. F5 exams are tough. Much tougher than any other vendor's exams I have ever taken. There is a learning curve there, for sure. But, if you pay proper attention to the blueprint and prepare accordingly, the PASS grade is a given ;-)
