Oracle Fusion Middleware 12c: Oracle Service Bus Essentials — Question 3

Which are two correct statements about backing up Exadata Database Machine? (Choose two.)

Answer options

• A. Backing up Exadata Storage Server Software is critical for restoration.
• B. Backup of the Oracle Cluster Registry, which also contains Voting Disk information, is automatically maintained on the file system of the first database server.
• C. For high availability, system area can be on the first two disks and M.2 devices.
• D. Use a snapshot-based backup of an Oracle Exadata Database Machine database server software.
• E. The M.2 disk is hot pluggable and can be replaced when the power is on, but you will have to restore the system data manually.

Correct answer: B, C

Explanation

Option B is correct because the Oracle Cluster Registry backup is indeed maintained automatically on the first database server's file system. Option C is also valid since having the system area on the first two disks and M.2 devices supports high availability. Options A, D, and E are incorrect as they either misrepresent the backup process or do not pertain directly to the correct backup statements.
