質問 # 17
A customer wants to select the pool for an application based on information found in the path of the URL.

http.//www.exampie.com/app 2 should be sent to the app2 pool
Which two profiles need to be assigned to the virtual server? (Choose two.)
- A. TTP Compression
- B. Client SSL
- C. HTTP
- D. TCP
- E. Persistence
正解：C、D
質問 # 18
An LTM Specialist needs to deploy a virtual server that will load balance traffic targeting https://register.example.com to a set of three web servers. Persistence needs to be ensured. No persistence mirroring is allowed SSL offloading is required.
A fourth web server with fewer resources will be used to handle requests from engine bots to https://register.example.comvrobots.txt by an iRule. The (Rule will use the HTTP_REQUEST event. .
What are the required profile and persistence settings to implement this
- A. tcp, clientssl, serverssl, ssl persistence
- B. tcp, clientssl, http. cookie persistence
- C. tcp, clientssl, http, serverssl cookie persistence
- D. tcp. dientssl, hup, source address persistence
正解：B
解説：
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.
