A company has a server that runs Windows Server 2012 R2. The Hyper-V role is installed on the server. The
server has virtual machines (VMs) that run Windows Server 2012 R2.
You create two VMs. You also create four virtual hard disks. Two of the virtual hard disks use the VHDfile
format and two use the VHDX file format.
You plan to create a failover cluster by using the two VMs on the Hyper-V host server.
You need to prepare the storage for the VMs.
What should you do?
A.
Enable virtual hard disk sharing for one of the VHDX-based hard disks.
B.
Run the Windows PowerShell cmdlet Optimize-VHD against the VHD-based hard disks.
C.
Enable virtual hard disk sharing for one of the VHD-based hard disks.
D.
Run the Windows PowerShell cmdlet Optimize-VHD against the VHDX-based hard disks.
Starting in Windows Server 2012 R2, Hyper-V makes it possible to share a virtual hard disk file between multiple virtual machines. Sharing a virtual hard disk file (.vhdx) provides the shared storage that is necessary for a Hyper-V guest failover cluster. This is also referred to as a virtual machine failover cluster.

KameX is correct. In case you were wondering about Optimize-VHD…
Optimize-VHD
http://technet.microsoft.com/en-us/library/hh848458.aspx
Optimizes the allocation of space used by virtual hard disk files, except for fixed virtual hard disks.
