Which statement about FlexCache capacity and data population is false?

Which statement about FlexCache capacity and data population is false?

• A. FlexCache volumes are sparsely populated and only contain data that clients have requested.
• B. FlexCache always pre-populates the full dataset of the origin volume.
• C. The FlexCache volume can expand dynamically as more blocks are cached.
• D. Cache size can be tuned to match workload requirements and expected data reuse.

Answer: (B)

FlexCache caches data on demand rather than loading the entire origin dataset up front. It stores only the blocks that clients actually request, so the cache is sparsely populated. This means the statement claiming the FlexCache volume always pre-populates the full dataset is false. As clients read new data, those blocks are fetched from the origin and stored in the cache, allowing the cache to grow to hold more blocks as needed. The cache size can be tuned to fit workload and data reuse, and the cache can expand dynamically as more blocks are cached, aligning capacity with actual access patterns and performance needs.
