I’m not sure, but A seems logical based on persistence.

I’m going with E. New connections could be routed there.

I believe it’s D. The pattern might favor the last unique connection.

I think it’s A too, but it could be tricky with multiple connections.

Wait, are we sure about that? What if the persistence profile changes?

B) 10.10.20.2:80 is the answer, no doubt about it. Unless, of course, the server is haunted by the ghost of connection C. Then we're all doomed!

Hmm, this one's tricky. I'm going to go with B) 10.10.20.2:80. Gotta love those source address persistence profiles!

This question feels familiar; I think we practiced something similar where the last connection determined the member. I just can't remember the exact details!

If I remember correctly, A was used twice, so maybe it will go to 10.10.20.1? But I feel like I need to double-check the rules on persistence.

I think the last connection from IP 205.12.45.52 would go to the same member as the last connection from A, but I'm not sure which one that is.

I've got a strategy - I'll carefully analyze the client IP, the last 5 connections, and the member options to determine the correct answer. Gotta stay focused on the details.

I'm a bit confused by the persistence profile and how it relates to the member selection. Can someone walk me through the logic here?

B) 10.10.20.2:80 is the correct answer. The question states that the persistence profile is based on source address, so the same client IP address will always be sent to the same member.

Ah, I see. The last 5 connections were A, B, C, A, C. So the persistence is based on the client IP address. I think I can work this out.

I remember something about source address persistence, but I can't recall how it applies to the last connections. Was it based on the most recent one?

Okay, let me think this through step-by-step. The question mentions a source address based persistence profile, so I need to focus on the client IP address.
