A vSphere administrator needs to place an ESXi host in maintenance mode to replace a hardware
component. This host is a member of a Virtual SAN cluster that uses Automatic Mode Disk
Groups. Availability of virtual machines running on this host is critical. HA and DRS are enabled on
the Virtual SAN Cluster. Otherwise, the Virtual SAN cluster uses default values.
Which action should the administrator take to automatically guarantee availability of virtual
machines with the fastest migration time?
A.
Select Enter Maintenance Mode and accept the default values
B.
Select Enter Maintenance Mode and select Full Data Migration option
C.
Select Enter Maintenance Mode and select No Data Migration option
D.
Migrate the virtual machines to another host and datastore then select Enter Maintenance
Mode
Explanation:
I think A. is the correct answer.
Take special attention at the DEFAULT VALUES and Virtual SAN in the link:

Remember that ONLY ONE Host in a Virtual SAN Cluster can be in Maintenance MODE!

A. The HOST will stay part of the Virtual SAN Cluster! (Which is asked for in the first sentence)
B. The HOST will STOP being part of the Virtual SAN Cluster!
C. Is an unstable option… (No data Migration:
Virtual SAN does not evacuate any data from this host. If you power off or remove the host from the cluster, some virtual machines might become unaccessible.)
D. Is an extension of ANSWER as B. (When evacuating data from the last host in the cluster, make sure you migrate the virtual machines to another datastore and then place the host in maintenance mode.)
This question asks for automation. Maintenance mode allows you to put a host into maintenance mode and have the VMs running on that host to automatically vMotion to other hosts.
As above, answer is A. Default option is “Ensure accessibility” which usually only requires a partial data evacuation, i.e. guarantee availability with fastest migration time.
