You have a server named Server1 that runs Windows Server 2012 R2. Server1 has the
Hyper-V server role installed.
You need to configure storage for a virtual machine to meet the following requirements:
Support up to 3 TB of data on a single hard disk.
Allocate disk space as needed.
Use a portable storage format.

What should you configure?

A.
A fixed-size VHDX

B.
A pass-through disk

C.
A fixed-size VHD

D.
A dynamically expanding VHDX

E.
A dynamically expanding VHD

Explanation:
Dynamically expanding virtual hard disk uses only as much physical storage space as it
needs to store the actual data that the disk currently contains. The size of the virtual disk’s
image file then grows as additional data is written to it.
