2V0-622 · Question #279

A vSphere administrator wants to upgrade NFS3 datastores to NFS4.1 on ESXi 6.5 hosts with running production virtual machines. Which option is valid?

The correct answer is C. Create a new NFS 4.1 datastore, and then use Storage vMotion to migrate virtual machines from. There is no in-place upgrade path from NFS 3 to NFS 4.1 in vSphere; the only supported migration method requires creating a new NFS 4.1 datastore and moving workloads to it.

Why each option

There is no in-place upgrade path from NFS 3 to NFS 4.1 in vSphere; the only supported migration method requires creating a new NFS 4.1 datastore and moving workloads to it.

ARun ESXi command to upgrade the datastore.

No ESXi CLI command exists to convert or upgrade a mounted NFS datastore from protocol version 3 to version 4.1.

BUnmount the datastore from a single host, then mount it as NFS 4.1 datastore, and repeat this

Unmounting from a single host and remounting as NFS 4.1 leaves other hosts still connected via NFS 3 and does not migrate VM files - it is not a valid upgrade path.

CCreate a new NFS 4.1 datastore, and then use Storage vMotion to migrate virtual machines fromCorrect

Storage vMotion allows live migration of virtual machine disk files from one datastore to another without powering off the VMs, making it the correct approach to move production workloads from an existing NFS 3 datastore to a newly created NFS 4.1 datastore. VMware does not provide an in-place protocol upgrade mechanism, so provisioning a new NFS 4.1 mount and migrating via Storage vMotion is the documented procedure.

DRight click the datastore and upgrade it as a NFS 4.1 datastore.

vSphere does not expose a right-click option to change the NFS protocol version of an existing datastore; no such UI upgrade wizard exists.
