Purely to renew the LTM exam, you can take the 301b (Troubleshooting) exam - that should renew your 301 and 201. Taking the DNS, ASM or APM, will NOT renew the LTM. The reasoning behind it, is that the modules are too different from eachother to warrant the renewal (which is quite annoying, but I tend to agree with).
Alternatively, if you pass your DNS exam as well, you can go for the Cloud Architect (402) exam, which will automatically renew the 301 and 302.
In my case, I renew my 401 one year, and the 402 the other, keeping all my 30X exams up-to-date.
The renewal of a certificate is a security process that has to be executed to avoid man in the middle or other common attacks regards certificates, if your F5 is local and you want to keep the same certificate for many years, you can renew the certificate internally for 10 or more years, probably in 10 years you have changed your F5 devices.
