Oracle Cloud Infrastructure 2023 Multicloud Architect Associate — Question 12

Which three statements are true about Exadata Snapshots on the Exadata Database Service? (Choose three.)

Answer options

• A. Exadata Snapshots utilize the Exadata SPARSE disk group to store the sparse files that contain all the data that is read and written by the Snapshots.
• B. Exadata Snapshots are unable to utilize all the Exadata features.
• C. Exadata Snapshots utilize the Exadata SPARSE disk group to store the sparse files that contain only changed blocks.
• D. Multiple users can create independent Exadata Snapshots from the same test master, which is a full Read-Only clone of the source database.
• E. Before creating Exadata Snapshots from the test master, you can modify the data in the test master, if required.

Correct answer: C, D, E

Explanation

The correct answer is C, D, E because Exadata Snapshots store only the changed blocks (C), allow multiple independent snapshots from a test master (D), and permit data modifications in the test master prior to snapshot creation (E). Options A and B are incorrect as they misrepresent the functionality and capabilities of Exadata Snapshots.
