Question
What is true regarding datastores on ESXi 6.x?
Options
- ANFS 4.1 datastore does not support Fault Tolerance (FT)
- BVMFS3 and VMFS5 datastores can be newly created
- CNFS datastore can be concurrently mounted using NFS 4.1 on one host and NFS on another
- DNFS 3.0 datastore does not support Fault Tolerance (FT)
Explanation
In vSphere 6.x, NFS 4.1 datastores are explicitly unsupported for Fault Tolerance, while NFS 3 datastores do support FT.
Common mistakes.
- B. VMFS3 cannot be newly created in ESXi 6.x - only VMFS5 can be created fresh; VMFS3 volumes can only exist as upgrades carried over from older environments.
- C. A single NFS datastore cannot be simultaneously mounted using different protocol versions across hosts - each NFS mount must use a single, consistent protocol version.
- D. NFS 3.0 datastores do support Fault Tolerance in vSphere 6.x; it is NFS 4.1 that lacks FT support, so this statement is the inverse of the truth.
Concept tested. NFS 4.1 Fault Tolerance datastore support limitations
