A host in a 4-node HA\DRS cluster has failed. HA initiates restart tasks for the virtual machines on
the remaining hosts in the cluster but half of them fail to restart.
What is the likely reason virtual machines fail to restart?

A.
HA admission control is blocking the restart of the virtual machines due to insufficient resources
to support the configured failover level of the cluster.

B.
The vMotion network has failed on the remaining hosts preventing the virtual machines from
migrating.

C.
Storage vMotion has failed on the datastore containing the virtual machines preventing them
from migrating.

D.
The failed host was the Master host in the cluster and no other hosts are able to perform the
necessary HA function to restart the virtual machines.
