EMC Proven Professional – Network Attached Storage Specialist — Question 7

What is the relationship between a storage volume and an extent?

Answer options

• A. A storage volume can be split into multiple extents
• B. An extent must map to an entire storage volume
• C. A storage volume can be created out of multiple extents
• D. An extent can span multiple storage volumes

Correct answer: C

Explanation

The correct answer is C because a storage volume can indeed be constructed from multiple extents, which allows for efficient allocation of space. Option A is incorrect as it implies that extents are a division of a volume rather than parts that can comprise it. Option B is also wrong because an extent does not need to encompass an entire volume. Lastly, option D is incorrect because extents are meant to be within a single storage volume.
