Which statement about FlexCache data population is true?

• A. FlexCache is sparsely populated and only stores data that clients have requested.
• B. FlexCache preloads the entire origin dataset on startup.
• C. FlexCache expansion is not supported after deployment.
• D. FlexCache caches only metadata.

Answer: (A)

FlexCache fills itself based on what clients actually request. It is sparsely populated, meaning it stores only the data blocks or files that clients have asked for, not the entire origin dataset. When a client requests something that isn’t yet in the cache, FlexCache fetches it from the origin and stores it locally, so subsequent requests for that data are served from the cache. This on-demand population reduces cache size, lowers startup latency, and gradually warms up with the workload. That’s why preloading the entire origin at startup isn’t how it operates, and why you can expand cache capacity after deployment. Also, the cache holds actual data blocks in addition to metadata; it’s not limited to metadata only.
