You work as a network administrator at ABC.com. The ABC.com network consists of an Active Directory Domain Services domain named ABC.com. All servers on the network run Windows Server 2008 R2 and all client computers run Windows 7 Enterprise.

A desktop administrator named Clive Allen is using a Windows 7 client computer to learn about PC virtualization. He has downloaded and installed Windows Virtual PC on his computer.

Clive wants to create multiple virtual machines (VMs) all running Windows XP Professional. Clive creates a VM named XP1. Clive asks you how he can easily create additional VMs and minimize the hard disk space used by the VMs.

What advice should you provide to Clive?

A.
You should advise Clive to create dynamically expanding virtual hard disks (VHDs) for the additional VMs.

B.
You should advise Clive to create fixed size virtual hard disks (VHDs) for the additional VMs.

C.
You should advise Clive to use Windows Explorer to make multiple copies of the virtual hard disks (VHD) file used by XP1.

D.
You should advise Clive to create differencing virtual hard disks (VHDs) for the additional VMs and configure them to use XP1’s VHD as the parent VHD.
