NetApp Certified Data Administrator (NCDA) – E-Series — Question 8

On your customer's AFF A700, there are multiple volumes within the aggregate aggr1. Within aggr1, volumes vol1, vol2, and vol3 store similar data, and volumes vol4 and vol5 store unique data.
In this scenario, which feature would improve storage efficiency with the data stored in volumes vol1, vol2, and vol3?

Answer options

• A. data compaction
• B. postprocess compression
• C. inline aggregate-level deduplication
• D. inline compression

Correct answer: A

Explanation

Data compaction is the correct choice as it reduces the size of similar data stored in multiple volumes, enhancing storage efficiency. The other options, like postprocess compression and inline compression, are effective but do not specifically address the redundancy among the similar data stored in vol1, vol2, and vol3 as effectively as data compaction does.
