Oracle Database Administration 2019 Certified Professional — Question 72

Which three statements are true regarding ACFS snapshots in Oracle 19c ASM? (Choose three.)

Answer options

• A. All ACFS snapshot operations for all filesystems are serialized clusterwide.
• B. They are contained in a directory on the same volume as their parent file system.
• C. They can be administered using ASMCMD.
• D. They are always point-in-time copies of the parent file system.
• E. You can create a snapshot from an existing snapshot.
• F. They can only be accessed when the file system is mounted.

Correct answer: B, C, E

Explanation

Option B is correct because ACFS snapshots are indeed stored in the same volume as the parent file system. Option C is also accurate as ASMCMD can be used to manage ACFS snapshots. Option E is true because creating a snapshot from an existing snapshot is allowed. Options A, D, and F are incorrect as they misrepresent the nature and accessibility of ACFS snapshots.
