Your network contains an Active Directory domain named contoso.com. The domain contains a Hyper-V
host named Server1. Server1 has an offline virtual machine named VM1 that is stored on a virtual hard
disk named VM1.vhd.
You plan to implement multiple virtual machines that have the same configurations as VM1. You need
to recommend a virtual hard disk solution for the planned implementation.
The solution must meet the following requirements:
Minimize the amount of time required to create the new virtual machines.
Minimize the amount of storage space required on Server1.
What should you include in the recommendation?
A.
Differencing VHD disks
B.
Dynamically expanding VHD disks
C.
Dynamically expanding VHDX disks
D.
Differencing VHDX disks

Should this answer not be D:, Differencing VHDX disks?

Both is an option but VHDX has much more features, and the requirements aren’t enough to make only one option correct.

The thing is, you cannot create a differencing VHDX file with a VHD file as a base.
So since the base disk is a VHD file, the differencing file also has to be in the VHD format, which explains why A is the correct answer.
