Your environment contains one Active Directory Domain Services (AD DS) domain. All domain controllers have Windows Server 2012 R2 installed. All domain controllers are virtualized domain controllers.
You design a disaster recovery strategy. You have the following requirements:
. The domain controllers can be recovered in the event that a Hyper-V host server fails.
. The AD DS domain must be restorable to a consistent state.
. You must minimize the data loss.
You need to ensure that the domain controllers can be recovered in the event of a failure. What should you do?
A. Clone the domain controller that holds the PDC Emulator role to a different Hyper-V host server. Schedule a Windows PowerShell job to run the Checkpoint-VM cmdlet on each virtual domain controller.
B. Run Windows Azure Hyper-V Recovery Manager.
C. On each guest operating system, run Windows Server Backup.
D. On the host operating system, run Windows Server Backup.
E. Schedule a Windows PowerShell job to back up each domain controller’s virtual hard disk (VHD) file.
