Troubleshoot High Availability and Disaster Recovery

Question

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?

Options

  • AClone the domain controller that holds the PDC Emulator role to a different Hyper-V host
  • BRun Windows Azure Hyper-V Recovery Manager.
  • COn each guest operating system, run Windows Server Backup.
  • Don the host operating system, run Windows Server Backup.
  • ESchedule a Windows PowerShell job to back up each domain controller's virtual hard disk

Explanation

Since all DCs are virtualized, it is possible to clone the PDC emulator. Since Windows Server 2012, AD DS employs safeguards on virtual DCs hosted on VM-GenerationID aware hypervisors and ensures that the accidental application of snapshots that could "rollback" a VM's state for example does not disrupt the AD DS environment.
