Which statement about DFS Replication uses remote differential compression to minimize bandwidth?

• A. DFSR uses remote differential compression to minimize bandwidth.
• B. DFSR replicates data in full each time.
• C. FRS uses differential compression.
• D. DFSR cannot replicate large files.

Answer: (A)

Remote Differential Compression lets DFS Replication send only the parts of a file that actually changed, rather than transferring the entire file. This is what DFSR uses to minimize bandwidth, making updates to large files much more efficient because only the altered blocks are transmitted and then reassembled on the destination. The statement reflects how RDC integrates with DFS Replication to reduce network load. In contrast, transferring complete files every time would waste bandwidth, FRS is an older system that doesn’t use RDC, and DFSR is capable of handling large files, so the idea that it cannot replicate large files isn’t accurate.
