質問 9

How does high availability clustering relate to periodic storage backup? (Choose TWO correct answers.)

A. Backup procedures may have to be adapted to the cluster to ensure complete and recoverable backups.

B. Regular backups become generally unnecessary as any data loss or corruption is automatically recovered by the high availability cluster.

C. Regular backups remain vital as they allow restoration of data that was accidentally deleted or corrupted.

D. Regular backups may be reduced to the cluster configuration and cluster state data as this information is sufficient to recover any state of the cluster, including data, at any time.
