What happens when a FlexCache cache miss occurs?

• A. The system fetches the data from the origin and caches it locally.
• B. The system serves stale data from cache.
• C. The system blocks the request until data is available from origin and never caches it.
• D. The system discards the request.

Answer: (A)

When a FlexCache cache miss occurs, the requested data isn’t found in the local cache. The system retrieves that data from the origin storage and then caches a copy locally so future requests for the same data can be served quickly from the cache. This behavior boosts performance by reducing repeated trips to the origin. The other options don’t fit because serving stale data would ignore the fresh fetch, blocking and never caching defeats the purpose of a cache, and discarding the request would lose data and degrade access reliability.
