Dell EMC Specialist – Systems Administrator, PowerStore — Question 6

In Isilon OneFS, what is a characteristic of CoW with snapshots?

Answer options

• A. Used for small changes, inodes, and directories.
• B. Avoids the double write penalty.
• C. Increases file fragmentation.
• D. Used for more substantial changes such as deletes.

Correct answer: A

Explanation

The correct answer, A, describes how CoW is specifically designed to handle small changes efficiently, particularly with inodes and directories. Option B is incorrect as CoW does not inherently avoid double write penalties; rather, it can introduce them. Option C is misleading because CoW typically helps manage fragmentation, and D is incorrect since CoW is not optimized for larger changes like deletions.
