What is the next step the vSphere administrator must use to provision the data disk?

A virtual machine requires a 4TB disk for application data. The storage administrator has already created and presented a 4TB LUN to an ESXi 5.x host. The host is currently configured with a single 500GB VMFS5 datastore.

What is the next step the vSphere administrator must use to provision the data disk?

A.
Create a virtual compatibility mode RDM mapping to the 4TB LUN.

B.
Create a physical compatibility mode RDM mapping to the 4TB LUN.

C.
Expand the existing VMFS volume to 4TB. Create a physical compatibility mode RDM mapping to the 4TB LUN.

D.
Expand the existing VMFS volume to 4TB. Create a virtual compatibility mode RDM mapping to the 4TB LUN.

Why physical compatibility and not virtual compatibility?

Because the size of RDM in Virtual Compatibility mode is limited to 2TB (-512 bytes).

RDM with Physical Comp. goes to 64TB (new in vSphere 5.x)
I believe this is called “Pass-Through” RDM in VMware documentation

Looks like B is the correct answer PRDM. It is the next step needed to avoid the 2TB limit of a VCRDM.
