Your network contains a server that runs Windows Server 2008 R2 Standard.
The server is configured to native boot from a virtual hard disk (VHD).
All hard disks on the server are configured as basic disks that use an MBR.
A new corporate security policy states that all of the hard disks on the server must use Windows BitLocker Drive Encryption (BitLocker).

You need to ensure that the server meets the corporate security policy.

What should you do first?

A.
Configure the disks to use a GPT.

B.
Convert the disks to dynamic disks.

C.
Upgrade the server to Windows Server 2008 R2 Enterprise.

D.

Configuring native VHD boot if the host volume is protected by BitLocker. You can save a VHD file on a file system that is protected by BitLocker, but you cannot use the VHD for native boot or enable Bitlocker on the volume(s) that are contained inside a VHD.
