What may be a cause for failure to unmount an NFS datastore?
A. It has active snapshot files.
B. It is being used for High Availability (HA) heartbeat.
C. It is part of a Cluster.
D. It is managed by Distributed Resource Scheduler (DRS).
Correct Answer: B
Explanation/Reference:
Explanation:
vSphere HA heartbeating does not prevent you from unmounting the datastore. If a datastore is used for heartbeating, unmounting it might cause the host to fail and restart any active virtual machine. If the heartbeating check fails, the vSphere Client displays a warning.
