A system administrator must mount a datastore to an ESXi host using NFSv4 with the NFS owner set to change/revoke access permissions. Which permission level must be applied to the NFS datastore?
The correct answer is A. Read/write, enable Root. Option A is correct because mounting an NFS datastore on ESXi requires Read/Write access so the host can store and modify VM data, and Enable Root (no root squash) is required because ESXi connects to NFS as the root user - without this flag, the NFS server squashes root to an…

Explanation
Option A is correct because mounting an NFS datastore on ESXi requires Read/Write access so the host can store and modify VM data, and Enable Root (no root squash) is required because ESXi connects to NFS as the root user - without this flag, the NFS server squashes root to an anonymous, unprivileged account, preventing the NFS owner from exercising change/revoke permission control.
Option B fails because Read-only prevents ESXi from writing VM files to the datastore, making it unusable for active workloads despite having Root enabled.
Option C fails on both counts - Read-only blocks write operations, and without Root enabled, the root identity is squashed, eliminating the owner's ability to manage access.
Option D fails because even though Read/Write is correct, omitting Root means the ESXi host's root-level NFS requests get remapped to an unprivileged user, breaking the permission management chain.
Memory tip: Think "RW + Root = Real control" - you need Read/Write to actually use the store, and Root enabled to preserve the owner's authority to revoke access. If Root is squashed, so is the owner's power.
