An administrator is deploying vSphere using a NAS device as the shared storage system. The
administrator has already created a VMkernel port, enabled the NFS client, and configured a
mount point accessible to the hosts.
Which additional configuration is required before the datastore can be used to create virtual
machines?
A.
The ESXi hosts must have root access to the datastore.
B.
The NAS must support NFS version 4.
C.
Port binding must be configured on the VMkernel port.
D.
The MTU on the VMkernel port must be set to 9000.
Explanation:
B – OK
The NFS server must allow read-write access for the root system account (rw).

You must also ensure that the vSphere host has root access to the datastore. This is typically done on NFS servers using the no_root_squash option in the /etc/exports file.
