- A. tcp, clientssl, http. cookie persistence
- B. tcp. dientssl, hup, source address persistence
- C. tcp, clientssl, serverssl, ssl persistence
- D. tcp, clientssl, http, serverssl cookie persistence
Answer: A
Explanation:
The option is wrong, it should be clientssl and serverssl. If the title requires ssl offload instead of encryption, you need clientssl instead of serverssl. irule needs HTTP profile to enable HTTP_REQUEST. If the session cannot be mirrored, the cookie session remains to meet the demand.
