Oracle Database 12c: RAC Administration — Question 27

Examine this command and output:
[root@host01 ~]# / sbin/acfsutil snap create snap001 /u0l/app/grid/acfsmount/ acfsutil snap create: Snapshot operation is complete.
Examine this command:
[root@host01 ~]# / sbin/acfsutil snap create p snap001
Snap002 /u01/app/grid/ acfsmount/
Which statement must be true for the successful execution of the second command?

Answer options

• A. The disk group compatibility attribute for ADVM must be set to 12.1 or higher.
• B. The parent snapshot must be read-only.
• C. The underlying ADVM volume must be configured with high redundancy.
• D. The parent snapshot must be read/write.

Correct answer: C

Explanation

The correct answer is C because a high redundancy configuration for the underlying ADVM volume is necessary for the snapshot to be successfully created. Options A and B are incorrect as they do not pertain to the requirements for creating a snapshot in this context, and D is also inaccurate since the parent snapshot needs to be in a high redundancy state rather than read/write.
