Question
An administrator wants to configure a High Availability cluster to allow virtual machines a 10 minute window to shut down in the event of a Host Isolation incident. What two configuration settings would satisfy this requirement? (Choose two.)
Options
- ASet the advanced option das.isolationshutdowntimeout = 10.
- BSet the advanced option das.isolationshutdowntimeout = 600.
- CConfigure Host Isolation Response to Shut Down and Restart VMs.
- DConfigure Host Isolation Response to Power Off and Restart VMs.

Why each option
A 10-minute graceful shutdown window for host isolation requires the timeout set to 600 seconds and the isolation response set to 'Shut Down and Restart VMs'.
das.isolationshutdowntimeout = 10 sets only a 10-second window, not 10 minutes, which does not satisfy the stated requirement.
The advanced option das.isolationshutdowntimeout accepts a value in seconds, so 600 equals exactly 10 minutes, giving VMs the required grace period before HA forces a restart.
'Shut Down and Restart VMs' invokes a guest OS shutdown via VMware Tools and honors the das.isolationshutdowntimeout value, enabling the configured grace period before HA restarts the VM.
'Power Off and Restart VMs' immediately cuts power to VMs without invoking a guest OS shutdown, so the das.isolationshutdowntimeout grace period is bypassed entirely.
