A system administrator must mount the NFS Datastore from a Dell Unity XT system to an ESXi host. Which permission level must they select when adding the host access to VMware NFS Datastore?

Question

Options

• ARead-only
• BRead/write, enable Root
• CRead/write
• DRead/write, Execute

• A
  3% (1)
• B
  87% (33)
• C
  8% (3)
• D
  3% (1)

Explanation

Read/write with Root access (option B) is required because ESXi hosts communicate with NFS datastores as the root user by default. Without enabling Root squash override (i.e., "enable Root"), the NFS server would squash root-level requests to an anonymous user, denying ESXi the permissions it needs to create, modify, and manage VMDK files on the datastore.

• A (Read-only) is wrong because ESXi must write to the datastore to create and run VMs - read-only would prevent any VM disk writes.
• C (Read/write) is wrong because, while it grants write access, it does not enable Root access, meaning root-level operations from the ESXi host get squashed by the NFS server and fail.
• D (Read/write, Execute) is a distractor - "Execute" is not a standard NFS host access permission option in Unity XT's NFS share configuration for VMware datastores.

Memory tip: Think "ESXi needs to be king of its datastore" - ESXi runs as root, so you must explicitly crown it by enabling Root access, otherwise the NFS server strips its privileges. No root = no crown = no datastore control.
