In a FlexCache deployment, who tracks the metadata and coherency information for the cache relationships?

• A. The origin volume
• B. The FlexCache volume
• C. The client applications
• D. The management LIF

Answer: (A)

In FlexCache, the origin volume is the central place that holds the authoritative file system metadata and the cache relationships. It tracks which data blocks are cached at edge caches and manages the coherency between those cached copies and the origin. The edge cache (FlexCache volume) stores the actual cached data but does not own or track the overall metadata or coherence state. Client applications simply request data; they don’t manage cache relationships, and the management LIF is used for control-plane operations, not for tracking cache metadata. So the origin volume is responsible for metadata and coherency information for the cache relationships.
