What is true regarding datastores on ESXi 6.x?

  • A. NFS 4.1 datastore does not support Fault Tolerance (FT)
  • B. Both VMFS3 and VMFS5 datastores can be created
  • C. NFS datastore can be mounted using NFS 4.1 on one ESXi host and NFS 3.0 on another
  • D. NFS 3.0 datastore does not support Fault Tolerance (FT)

Suggested Answer: A 🗳️
VMs on NFS v4.1 support FT, as long as it is the new FT mechanism introduced in 6.0.
VMs running on NFS v4.1 do not support the old, legacy FT mechanism.
In vSphere 6.0, the newer Fault Tolerance mechanism can accommodate symmetric multiprocessor (SMP) virtual machines with up to four vCPUs. Earlier versions of vSphere used a different technology for Fault Tolerance (now known as legacy FT), with different requirements and characteristics (including a limitation of single vCPUs for legacy FT VMs).
