Oracle Database 12c: Advanced Administration — Question 105

Examine the command to back up the ASM metadata:
ASMCMD>md_backup /backup/ASM_backup
In which three situations can you use the backup?

Answer options

• A. when one or more disks in an ASM disk group are lost
• B. when the data file on an ASM disk group gets corrupted
• C. when one of the disks in a disk group is accidentally unplugged
• D. when one or more file directory paths are accidentally deleted from an ASM disk group
• E. when all the ASM disk groups for the ASM instance are lost

Correct answer: B, C, D

Explanation

The correct answer includes scenarios where the backup can restore essential data after a loss or corruption. Option B is valid as it addresses data file corruption, option C is correct since unplugging a disk can lead to data access issues, and option D is relevant for restoring lost directory paths. Options A and E are incorrect as they involve complete loss of disks or groups, which would require a different recovery strategy.
