Your company has an Active Directory directory service domain. You have a four-node failover cluster that is a member of the domain. You perform a quarterly Automated System Recovery (ASR) backup of the cluster, and you perform daily backups by using Windows Backup. A cluster disk fails. You need to restore the cluster disk signature to the failed cluster disk.

B.
Use the Cluster Administratortool.

C.
Power down the node with the failed cluster disk, and then use the ASR functionality.

D.
Power down all cluster nodes other than the node with the failed cluster disk, and then use the ASR functionality.
