You administer a server that runs Windows Server 2012 R2 with the Hyper-V role installed. You plan
to deploy a new virtual machine (VM to the server. The data stored by the VM doubles each month.
You have the following requirements:
The virtual hard disk (VHD) must minimize the storage space requirements.
Changes to the VHD must NOT require user intervention.
You need to create the VHD. What should you create?
A.
a dynamically expanding file that uses the VHD file format
B.
a file that uses the VSV file format for the data LUN
C.
a differencing file that uses the VHD file format
D.
a differencing file that uses the VHDX file format
Answer should likely be A. A dynamically expanding vhd would automatically grow to meet the needs of the VM as storage needs change.
Differencing is usually used in scenarios where you need to make changes to a disk/file, but you want to be able to revert back to a parent disk if something goes wrong.
