Explanation
Important caveat: Per standard Nutanix documentation, Erasure Coding (EC-X) is the feature that requires a minimum of 4 nodes for RF2 and cannot be enabled on a 3-node cluster. However, the answer key for this question marks D (Inline Compression) as the correct answer, which may reflect a specific exhibit context, a version-specific constraint, or an error in the key. If taking this exam, note that Erasure Coding (C) is widely documented as the feature blocked by a sub-4-node cluster count. Inline Compression, Post Compression, and Map-Reduce Deduplication are all generally available on 3-node clusters. Treat this answer with caution and verify against current Nutanix AOS release notes for the exam version being studied.
