A host in a vSphere environment needs to be taken offline for hardware maintenance. An administrator needs to put the host in maintenance mode without causing VM downtime.
What three steps should the administrator follow? (Choose three.)
A.
Select the "Fractional data migration" option
B.
Migrate all VMs off the host using vMotion
C.
Verify that no VMs are running on the host before maintenance
D.
Select the host and enter maintenance mode from the vSphere Client
E.
Ensure that the host is not part of a vSphere HA cluster
Using vMotion to migrate all virtual machines off the host ensures that there is no downtime for the VMs during the maintenance process.
The administrator should then select the host and initiate maintenance mode from the vSphere Client to begin the maintenance process.
Ensuring the host is not part of a vSphere HA cluster before maintenance is important to avoid triggering unnecessary VM restarts or failovers during the process.
