NetApp Certified Storage Associate (NCSA) — Question 13

A new storage efficiency job is executed on a volume hosting only a thick-provisioned LUN. Although 45% of the space was saved, no extra space was seen by the client.
In this scenario, which statement is correct?

Answer options

• A. The client sees only the logical space for the LUN.
• B. There are volume Snapshot copies that were taken before the efficiency job.
• C. The client needs to re-scan the volume to detect the changes.
• D. The volume is thin provisioned.

Correct answer: C

Explanation

The correct answer is C because a re-scan is necessary for the client to see the results of the storage efficiency job. Option A is incorrect as it does not explain the lack of visible space savings. Option B does not address the immediate issue of space visibility post-efficiency job. Option D is incorrect since the scenario specifies a thick-provisioned LUN.
