Refer to the exhibit.
A web application is configured to allow sessions to continue even after a user computer is shut down for the night. A new LTM device is configured to load balance the web application to several servers. The application owner reports that application users are logged out of the web application whenever their browser is restarted or computer is rebooted.

Definitely a persistence problem, no doubt about it!

Wait, are users really logged out just from a reboot? That seems odd.

I think it's more about persistence mirroring, though.

I agree, it's probably the 'Expires' value that's missing.

Sounds like a cookie issue to me.

I think the cookie not being passed correctly could also be a reason for users getting logged out. I need to double-check how that works with the LTM device.

I feel like the problem could be related to the persistence mirroring, but I can't recall the specifics of when that is necessary.

This question seems similar to one we practiced where the cookie didn't have an 'Expires' value. I think that might be the issue here too.

I remember we discussed persistence in our last class, but I'm not entirely sure if it's about the virtual server or the cookie settings.

Okay, I've got a strategy - I'll methodically go through each answer choice and evaluate how it could be causing the logout issue. Persistence configuration seems like the most likely culprit.

I'm a bit confused by the load balancing aspect. Does that play a role in the logout problem? I'll need to think through how the LTM device interacts with the web servers.

Hmm, the key seems to be the issue with sessions persisting after a reboot. I'm thinking it's probably a persistence configuration problem on the LTM device.

This looks like a tricky one. I'll need to carefully read through the details to understand the problem.

Ah, I bet it's the cookie issue. The LTM device must not be properly handling the session cookie from the web app.

I bet the dev team is kicking themselves over this one. Persistence mirroring would have solved this issue elegantly. Someone's getting a late night on-call this week.

Ha! Rookie mistake. The LTM device is clearly not passing the server-set cookie to the clients. That's the root cause for sure.

C) The cookie set by the LTM device does NOT have an 'Expires' value.

Hmm, I'm not so sure. The cookie 'Expires' value could also be the problem if it's not set correctly. The LTM might not be able to recognize the session then.

But could it also be that the cookie set by the LTM device does NOT have an 'Expires' value?
PE

The lack of persistence configuration on the virtual server is definitely the issue here. Without it, the LTM device can't maintain the session state across reboots.

Once persistence is configured, users should stay logged in even after browser restarts.
CL

We should configure persistence on the virtual server to solve this problem.

Agreed, without persistence, the session state can't be maintained across reboots.

I agree with Sabine. Without persistence configured, the sessions will not be maintained.

I think the problem is that the virtual server does NOT have persistence configured.
