Which statement accurately differentiates FlexCache from SnapMirror?

Which statement accurately differentiates FlexCache from SnapMirror?

• A. SnapMirror is a caching solution for hot data.
• B. FlexCache caches active-write data for performance.
• C. Both FlexCache and SnapMirror use synchronous replication.
• D. FlexCache caches active-read data for performance; SnapMirror replicates data for protection.

Answer: (D)

FlexCache is about speeding data access by storing actively read data at the cache, so subsequent reads come from the local cache rather than the remote source. It does not cache writes; write operations still go to the origin. SnapMirror, in contrast, is a data-protection feature that replicates data to a remote cluster to support disaster recovery and failover. It’s about maintaining a copy for protection rather than speeding up reads. So the accurate differentiation is that FlexCache caches active-read data for performance, while SnapMirror replicates data for protection. The other statements misstate FlexCache’s purpose (caching writes) or SnapMirror’s role (caching vs replication), and ignore that replication modes can vary for SnapMirror.
