You have a server named Server1 that runs Windows Server 2012.
You add a 4-TB disk named Disk 5 to Server1.
You need to ensure that you can create a 3-TB volume on Disk 5.
What should you do?

A.
Create a storage pool.

B.
Convert the disk to a dynamic disk.

C.
Create a VHD, and then attach the VHD.

D.
Convert the disk to a GPT disk.

Explanation:
MBR max is 2TB, the disk must be GPT
For any hard drive over 2TB, we need to use GPT partition. If you have a disk larger than 2TB size, the rest
ofthe disk space will not be used unless you convert it to GPT.
An existing MBR partition can’t be converted to GPTunless it is completely empty; you must either
deleteeverything and convert or create the partition as GPT.
It is not possible to boot to a GPT partition, impossible to convert MBR to GPT without data loss.
