In data deduplication, to which location are chunks moved to improve performance?

• A. Disk Cache
• B. The outer ring of the drive plate
• C. The Azure Cloud
• D. Memory

Answer: (D)

In data deduplication, performance is boosted by keeping frequently accessed chunks in fast memory. The dedup process stores the unique chunks on disk, but to speed up lookups, hash checks, and retrieval, recent or hot chunks are cached in RAM. This in-memory cache minimizes disk I/O, reducing latency and speeding both writes and subsequent reads. The other options don’t fit the typical dedup workflow: disk cache is a broader caching layer and not as fast as RAM for active data, the Azure Cloud isn’t involved in the local dedup store, and the outer ring of a drive plate has no bearing on how dedup chunks are managed.
