You deploy two Windows Server 2008 R2 Hyper-V servers. You manage the servers by using Microsoft System Center Virtual Machine Manager (VMM) 2008 R2. You need to ensure that you can restore virtual machines (VMs) in the event of a hardware failure.

What should you do?

A.
Use a PowerShell script to create a snapshot of each VM. Run the script every 60 minutes on each Hyper-V server.

B.
Use a PowerShell script to create a checkpoint of each VM. Run the script every 60 minutes on each Hyper-V server.

C.
Use a PowerShell script to pause, export, and start each VM, and then to copy the export to the opposite Hyper-V server. Run the script once per day on each Hyper-V server.

D.
Use a PowerShell script to shut down, export, and start each VM, and then to copy the export to the opposite Hyper-V server. Run the script once per day on each Hyper-V server.
