F5 System Engineer LTM Certified

Yesterday I passed the second and final exam in the F5 System Engineering track F50-522. Without breaking NDA lets go into an overview of the exam :
- As I mentioned in LTM Essentials F50-521 exam, the questions are mostly based on theory. So you need to know hot things works instead of how things are done. Having more then 3 years of hands on with those devices, I really had hard time on some of the questions :)
- Majority of the questions requires you to have a deep understanding of Virtual Server types (network,transparent,forwarding), SNAT/NAT concepts like automap and how source and destination IP@ changes from client to member node.
- Master the iRules. Know the context for each method. Know how context changes the behavior of local_address/remote_address etc..
- Master TCL functions like findstr,starts_with,ends_with etc..
- Know variety of logging options like alertd,syslog-ng and snmpd
- And for sure you need to have a good understanding of how HTTP works. Cookies, Keep-alive messages and their interaction with One-Connect profiles, XForward headers etc..
