A SAN administrator recently installed a storage encryption switch on the Fibre Channel
Fabric. Shortly after the deployment, several new VMFS5 datastores recently created were
dismounted. Attempts to manually mount them fail. VMFS5 upgraded datastores are
unaffected. All Storage arrays in use support VASA and VAAI. What is the root cause of this
problem?

A.
All newly created VMFS5 datastores are tagged ATS_Only. The storage encryption
switch blocks the ATS command.

B.
All newly created VMFS5 datastores are tagged XCOPY_Only. The storage encryption
switch blocks the XCOPY command.

C.
All newly created VMFS5 datastores are tagged WRITE_SAME_Only. The storage
encryption switch blocks the WRITE_SAME command.

D.
All newly created VMFS5 datastores were formatted with 1MB block size. The storage
encryption switch does not support this block size.
