单项选择题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

单项选择题You configure a Windows Server 2008 R2 Hyper-V server with several virtual machines （VMs）. A software vendor releases a software update for an application that runs on only one of the VMs. You need to plan a strategy that enables you to install and test the update without interrupting business operations and without corrupting data.   What should you do first？（）

A.Export the VM
B.Create a snapshot of the affected VM
C.Enable the Windows Volume Snapshot Service on the affected VM
D.Enable the Windows Volume Snapshot Service on the Hyper-V server
