VMware App Volumes 4 Specialist — Question 18

Which two statements are true about enabling deduplication and compression on an All-Flash vSAN cluster with data? (Choose two.)

Answer options

• A. On-disk format version 3.0 or later is required to support deduplication and compression.
• B. This can be enabled through storage policies and does not require any data migration.
• C. Deduplication and Compression cannot be enabled on an existing vSAN datastore with data.
• D. Move one host at a time to maintenance mode and enable deduplication and compression.
• E. This requires data evacuation and disk format upgrade of all the disk groups.

Correct answer: A, E

Explanation

The correct answers, A and E, are accurate because deduplication and compression require a specific on-disk format and necessitate data evacuation and disk format upgrades. Options B and C are incorrect as they misrepresent the requirements for enabling these features on an existing vSAN datastore. Option D is not applicable since it incorrectly suggests a method that does not align with the requirements.
