Which statement accurately differentiates FlexCache from SnapMirror?

Which statement accurately differentiates FlexCache from SnapMirror?

• A. SnapMirror is a caching solution for hot data, while FlexCache is read-only.
• B. FlexCache caches active-read data for performance; SnapMirror replicates data for protection.
• C. Both FlexCache and SnapMirror perform asynchronous replication using checkpoints.
• D. FlexCache volumes can only be created on the same cluster as the origin.

Answer: (D)

FlexCache is a caching layer that brings hot, active-read data closer to clients to boost performance, reducing latency for frequently accessed data. SnapMirror, on the other hand, is a data protection feature that asynchronously copies data to a secondary system so you can recover in case of a failure. Because one is about speeding access to data and the other is about protecting data through replication, the accurate differentiator is that FlexCache caches for performance while SnapMirror provides replication for protection. The other statements aren’t accurate: FlexCache is not a read-only caching solution—it serves cached data to improve performance while still reflecting updates from the origin. SnapMirror isn’t a caching mechanism. And FlexCache isn’t restricted to creating volumes on the same cluster as the origin; cache can reside on a different cluster to serve remote users.
