Not C. Match Across Services requires the virtual servers to reference the same pool to share persistence records. If the pools are different — even if they contain the same members — it will not work. 3 seperate services, so 3 seperate pools. "D" is the correct answer.

This is a broader version of "Match Across Services." It allows sharing persistence records across any Virtual Server using that profile, even if they have different IP addresses. While it would technically work, "Match Across Services" is the more specific and standard choice when dealing with multiple ports on the same application IP. So, the best choice is C.

I vote C. Match across service is used when you have multiple Virtual servers with same IP, but different services. In our case, there is no mention of different IPs, meaning we have to configure match across service as best option.
