Refer to the exhibit.
A BIG-IP Administrator needs to deploy an application on the BIG-IP system to perform SSL offload and re-encrypt the traffic to pool members.
During testing, users are unable to connect to the application.
What must the BIG-IP Administrator do to resolve the issue?
- A. Remove the configured SSL Profile (Client)
- B. Enable Forward Proxy in the SSL Profile (Client)
- C. Configure an SSL Profile (Server)
- D. Configure Protocol Profile (Server) as splitsession-default-tcp
Answer: C
Explanation:
Explanation
According to the requirements of the subject, the client and server must be configured with ssl profile.
NEW QUESTION 39
Some users who connect to a busy Virtual Server have connections reset by the BIG-IP system. Pool member resources are NOT a factor in this behavior. What is a possible cause for this behavior?
- A. The Rewrite Profile has NOT been configured.
- B. The Connection Rate Limit is set too high
- C. The Connection Limit is set too low.
- D. The server SSL Profile has NOT been reconfigured.
Answer: C
Explanation:
The topic explains that the connection reset behavior is caused by the vs configuration rather than the server resource problem. The answers B C are all configuration at the service forwarding level. If there is a problem with the configuration, it is all a problem rather than some users. Answer C's Connection Limit will cause a reset behavior when the connection reaches the threshold.
