Which of the following descriptions about the snapshot backup of the OceanStor backup solution are correct? (Multiple choice)

A.Offline backup of snapshots. The backup adopts offline mode and does not occupy the resources of the production system.

The volume where the file system is located cannot be automatically discovered and needs to be configured separately.

C.After the snapshot is completed, you can choose to catalog and index the snapshot data (to ensure application-level recovery or small particle recovery).

D.After the snapshot backup is adopted, data can be recovered from the recovery layer and the protection layer. The compliance layer has a special purpose and cannot be used for data recovery.

Question 173

Which of the following statements about AK/SK authentication process is incorrect?

A.After SK is queried, the OceanStor 9000 uses the MD5 algorithm to encrypt SK and request content, and then generates a signature.

C.After receiving the request and signature, the OceanStor 9000 uses AK to query SK.

D.The OceanStor 9000 compares the received signature with the one that calculated by the system. If the two signatures are consistent, the authentication succeeds,
