An administrator is implementing a VDI solution. The workload will be a series of persistent desktops in a dedicated storage container within a four-node cluster Storage optimizations should be set on the dedicated storage container to give optimal performance including during a node failure event

Compression Deduplication and Erasure Coding
Suggested answer: D

Explanation:

According to the web search results, three storage optimizations that should be set on a dedicated storage container for a VDI solution with persistent desktops are compression, deduplication and erasure coding. Compression is a technique that reduces the size of data by removing redundant information. Deduplication is a technique that eliminates duplicate copies of data blocks and stores only unique blocks.Erasure coding is a technique that increases usable capacity by reducing the replication factor of data blocks and using parity information instead7.These three optimizations can improve performance and save storage space for VDI workloads, especially during a node failure event when data needs to be rebuilt from parity information8.The administrator can enable these optimizations by using Prism Element web console or ncli command-line interface9.
