An administrator is tasked with optimizing storage for persistent VDI desktops.

Comprehensive and Detailed Explanation From Exact Extract of Nutanix End User Computing documents:

According to Nutanix Storage Best Practices for Citrix/VDI:

Workload Type: The question specifies Persistent VDI, which typically uses Full Clones.

Deduplication: For Full Clones/Persistent Desktops, the data (OS and Apps) is identical across many VMs but stored independently. Deduplication (specifically Capacity Tier Deduplication) is Enabled to eliminate these redundant blocks and save significant capacity.

Compression: Inline Compression is Enabled by default and recommended for all VDI workloads to improve performance and capacity usage.

Erasure Coding (EC-X): Nutanix documentation explicitly states that Erasure Coding is Disabled for active VDI workloads. EC-X provides capacity savings for "write-cold" data (like backups or archives) but introduces a performance penalty (parity calculation overhead) on random writes, which are common in persistent desktop usage.

Correction: While option D suggests enabling everything, the specific best practice table for "Citrix MCS: Full Clone" lists Erasure Coding as Disabled to maintain optimal user experience.
