An administrator needs to upgrade a Unified Access Gateway (UAG) appliance. The UAG is connected to a load balancer with other UAGs and has existing sessions.

Which option provided allows minimal downtime for maintenance?

Show Suggested Answer Hide Answer
Suggested Answer: A

Enabling Quiesce Mode in the Unified Access Gateway (UAG) Admin UI is the recommended approach for minimizing downtime during maintenance or upgrades when the UAG is part of a load-balanced cluster. Quiesce Mode allows the UAG to stop accepting new connections while allowing existing sessions to continue until they naturally end. This ensures minimal disruption to users and allows for a controlled upgrade process.

B and D are definitely not the right choices, those will cause more downtime.

Not sure about that, isn’t suspending the UAG also a good option?

Powering off the UAG seems like the worst option, but I can't recall if removing the thumbprint would help with downtime.

I feel like I've seen a similar question where minimizing downtime was key, and Quiesce Mode was the answer there too.

I'm not entirely sure, but I remember something about suspending the UAG appliance being risky because it could still affect active sessions.

I think enabling Quiesce Mode might be the right choice since it allows existing sessions to finish without dropping them.
