Not sure about that, could be something else entirely.

I feel like the "Unable to connect" message might relate to the virtual server being disabled on VLANs, but I need to double-check that.

The protocol seems off to me. I thought virtual servers needed to match the pool member's protocol, but I'm not completely confident.

I think we practiced a similar question where a pool member was down due to a monitor. Could that be what's happening here?

I remember something about VLANs being disabled could cause connectivity issues, but I'm not sure if that's the main problem here.

I'm a bit confused by the "translate-address" and "translate-port" settings. I'll need to research what those do to see if they could be causing the issue.

The pool member address is 172.16.20.1, so I'll check if that server is actually up and running the application.

Okay, let me think this through step-by-step. The "Unable to connect" message suggests a connectivity issue, so I'll focus on the pool member status.

Hmm, the virtual server is set to UDP protocol, but the pool member is likely expecting TCP. That could be the problem.

Looks like the LTM Specialist needs to brush up on their protocol knowledge. UDP for an HTTPS virtual server? That's like trying to pour water into a teapot!

I think the pool member is marked down by a monitor. The connection directly to the pool member is working, so the issue must be with the virtual server configuration.

The virtual server is configured for UDP protocol, but the application is running on TCP (HTTP/HTTPS). This is likely the issue, so I would choose D.

We should change the virtual server configuration to use TCP protocol instead.
