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

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

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.
