An administrator attempts to create a Thick Provisioned Virtual Disk (VMDK) on an NFS datastore; but it fails.
Which two reasons would explain the failure? (Choose two.)
A. Datastore is on an NFS 3 storage server that does not support Hardware Acceleration
B. Datastore is on an NFS 4.1 storage server
C. Only VMFS datastores support "Thick Provisioned" VMDK
D. The NFS datastore was not created on a "Thick Provisioned" device

“NFS 4.1 does not support hardware acceleration. This limitation does not allow you to create thick virtual disks on NFS 4.1 datastores.”
Me too 🙂
As per this doc A and D seems to me to be the correct answers: https://docs.vmware.com/en/VMware-vSphere/6.7/com.vmware.vsphere.storage.doc/GUID-F0FA0117-D48F-4F6F-BE3F-A06BF26F742C.html#GUID-F0FA0117-D48F-4F6F-BE3F-A06BF26F742C.
can anyone clarify whey B is correct.
NFS 3 and NFS 4.1 support hardware acceleration that allows your host to integrate with NAS devices and use several hardware operations that NAS storage provides. For more information, see Hardware Acceleration on NAS Devices.
I think the correct answers are A and D.
