A Windows 8.1 computer hosts multiple virtual machines. The computer contains one hard drive with two partitions.
You need to configure a new virtual machine to use the second physical partition of the host computer as the primary boot device.
What kind of virtual hard disk should you use?
A. Pass-through
B. Fixed-size
C. Differencing
D. Dynamic
Correct Answer: A

VHDs: Fixed, Dynamic, Differencing
By default, new VMs are created with an attached VHD. These disks represent Microsoft’s open format for virtual disks, and they have some very useful benefits.
..
Another important consideration with Hyper-V disks is managing storage capacity. Hyper-V has three options for creating new VHDs: fixed size, dynamically expanding, and differencing. As you can probably guess, fixed-size VHDs provision the entire disk size as the disk is created. Dynamically expanding disks consume only as much space as is actually used by data on the disk.
..
Differencing VHDs let you link multiple VHDs to one another.
..
Pass-Through Disks
Yet another type of disk, called a pass-through disk, isn’t a VHD at all. These disks are created by attaching a disk volume to a Hyper-V host, typically through either an iSCSI or Fibre Channel connection. After the disk volume is attached to the Hyper-V host, the disk is then passed through to an awaiting VM-- hence the name.
