SG0-001 · Question #96

Which of the following would benefit the MOST from deduplication?

The correct answer is B. Virtualized servers. Deduplication achieves the greatest storage savings on datasets with high redundancy, where many identical blocks of data exist.

Why each option

Deduplication achieves the greatest storage savings on datasets with high redundancy, where many identical blocks of data exist.

ADatabase

Databases often contain unique, frequently changing data blocks, which generally have low redundancy and therefore do not benefit significantly from block-level deduplication.

BVirtualized serversCorrect

Virtualized servers (and VDI environments) typically benefit the most from deduplication because multiple virtual machines often share identical operating system files, application binaries, and libraries. This high degree of common data across many instances allows deduplication to achieve significant storage savings by storing only one unique copy of these shared data blocks.

CCompressed videos

Compressed videos are already highly optimized and have very little redundant data at the block level due to prior compression, making them poor candidates for further space savings through deduplication.

DCompressed photos

Compressed photos, similar to compressed videos, have already undergone compression, which reduces redundancy, meaning deduplication offers minimal additional storage savings.
