Click the Exhibit button.
An administrator successfully updates and deploys a new Pattern file and scan engine to all Normal Servers in the network. The administrator then installs five new Normal Servers in subnet B to the Information Server in subnet A using the Management Console (as shown in the exhibit).
A few hours after the last Normal Server has been successfully installed, the administrator notices that ALL Normal Servers are suffering from performance degradation and decides to roll back the scan engine on the servers. After the rollback has been completed, the administrator notices that the five newly installed servers did not roll back to the previous scan engine. What is the cause of the problem?

I agree, communication issues could also be a factor here.

Wait, so they can't roll back if there's no previous version? That's surprising!

Definitely a sync issue with the Information Server.

I think it's more about them not finishing registration.

Sounds like they didn't have a previous scan engine to roll back to.

I'm leaning towards option A, but I can't recall if communication issues would prevent a rollback. It feels like there could be multiple factors at play here.

This seems similar to a practice question we did about server synchronization. Could it be that they need to sync with the Information Server after installation?

I’m not entirely sure, but I think the new servers might not have a previous scan engine to roll back to since they were just installed.

I remember something about servers needing to register properly with the Information Server before they can receive updates. Maybe that's the issue here?

Hmm, I'm a bit unsure about this. I'll need to review my notes on stress and try to remember the key aspects of the definition.

I'm a bit confused by the options here. They all sound like they could be the first stage. I'm going to have to think this through carefully and review my notes before answering.

This looks like a tricky question. I'll need to think carefully about the different proxy techniques to determine the most advanced one.

"Wait, I'm a little confused. Does the $slice operator start counting from the beginning or the end? I can never remember which way it goes. Hmm, I better review my MongoDB query notes before answering this one."
