Which process will the vSphere administrator use to provision the data disk?

The database server administrator requests a virtual machine with a small system disk and a single data disk that must be 3TB in size. The storage administrator has already created a 3TB LUN. A 500GB VMFS3 datastore already exists.

Which process will the vSphere administrator use to provision the data disk?

A.
No action is required on the VMFS3 Datastore. On that volume, creates a critical compatibility mode RDM mapping to the 3TB LUN.

B.
No action is required on the VMFS3 Datastore. On that volume, create a physical compatibility mode RDM mapping to the 3TB LUN.

C.
Upgrade the VMFS3 Datastore to VMFS5. On that volume, creates a physical compatibility mode RDM mapping to the 3TB LUN.

D.
Upgrade the VMFS3 Datastore to VMFS5. On that volume create a virtual compatibility mode RDM mapping to the 3TB LUN
