An HA pair of LTM devices configured in Active-Standby mode stops responding to traffic and causes an outage. The Active device becomes Standby, but the partner device stays in Standby mode instead of taking over as Active. A reboot and restart of the services brings the LTM device to Active mode for a short time, but then it goes into Standby mode again.
Which two configuration components caused this condition? (Choose two.)

Nah, I don't buy that. Must be something else at play.

System Fail-safe could also be a factor, for sure.

Surprised the Standby didn't take over! What's going on?

I think it's more about the Link down on Failover.

Definitely looks like VLAN Fail-safe is a culprit here.

I feel like Gateway Fail-safe might be involved as well. It’s tricky because I can’t recall the exact scenarios where it applies.

I practiced a similar question where Link down on Failover was the answer. It makes sense here too, but I'm not completely confident.

I'm not entirely sure, but I think System Fail-safe could also be a factor. It seems like it could prevent the standby from taking over.

I remember studying VLAN Fail-safe and how it can impact the failover process. It might be related to this issue.

I'm a bit confused by this question. I know the UiPath Robotic Enterprise Framework has different workflows, but I'm not sure which one is responsible for incrementing the TransactionNumber variable. I'll have to think this through.

Ah, I've seen questions like this before. The key is understanding the directionality of the APIs in a software-defined network. I think I've got this one figured out.

Ah, this is a good one. I think the answer is probably B, where the libraries are assigned by the client application. That way, the stored processes don't have to worry about it.

Local alarm system sounds like it could be right, but what about auxiliary systems? They might also connect to emergency services.
