Which term describes a feature that can save large amounts of storage space when used for Hyper-V machine storage?

• A. System Insights
• B. Server Core App Compatibility Feature on Demand
• C. Deduplication for ReFS volumes
• D. Shielded VMs for Linux

Answer: (C)

The feature being tested is data deduplication on ReFS volumes. Data deduplication identifies identical data blocks across files and stores only one copy of those blocks, with references from all the affected files. For Hyper-V storage, many virtual machines often contain similar OS files and base images; deduplicating at the volume level means all those duplicate blocks are stored once, dramatically reducing the total space required for VM disks stored on that ReFS volume. The other options don’t directly reduce VM storage: System Insights analyzes resource usage, App Compatibility Feature on Demand is about enabling components, and Shielded VMs for Linux focuses on security and isolation, not space savings.
