Question

You manage a pooled AVD host pool with 10 session hosts serving 200 users. You need to apply an out-of-band security patch to three session hosts during business hours. The patch requires a reboot, but you must prevent new user connections from landing on those three hosts while allowing users already connected to keep working until they naturally log off. What should you do first?

Accepted Answer

Set the three session hosts to drain mode (allow new sessions = No) in the host pool

Answer

Reduce the host pool maximum session limit to zero for the three session hosts

Answer

Force log off all active users on the three session hosts, then apply the patch

Answer

Remove the three session hosts from the host pool and re-register them after patching
