In a FlexCache deployment, how are write operations typically handled with respect to the origin?

• A. Writes are always committed directly to the origin.
• B. Writes are cached locally and never sent to the origin.
• C. Writes are written to a separate backup cache and later flushed to origin.
• D. Writes are performed only on the FlexCache and do not affect the origin.

Answer: (A)

FlexCache acts as a caching layer in front of the origin, with the origin serving as the authoritative data store. When a write occurs, it is sent to the origin for persistence, so the origin is updated and all clients and caches see a consistent state. This write-through behavior prevents data divergence between the cache and the origin and simplifies coherence and failover handling. If writes were only cached locally or sent to a separate backup cache, or if writes happened only on the cache and did not touch the origin, different clients could observe stale or inconsistent data, and data could be lost if the cache failed.
