F5 301B BIG-IP LTM case studies
F5 301B BIG-IP LTM · Put your knowledge to work in context.
The F5 301B BIG-IP LTM exam is the specialist-level certification test for administrators and engineers who build, tune, and troubleshoot Local Traffic Manager objects on a BIG-IP system. It is aimed at people with hands-on operational experience: you are expected to reason about how a virtual server, profile stack, pool, persistence setting, and monitor interact to produce the traffic behavior a user sees, rather than just recall where a checkbox lives. The exam covers virtual server and profile configuration, load balancing methods, persistence, health monitoring, SSL/TLS termination and client certificates, iRules, and the troubleshooting workflow that ties them together. Preparation works best in layers. The F5 301B BIG-IP LTM case studies are 5 cases and about 2,620 words.
