Which statement about FlexCache namespaces is correct?

• A. The cache only contains a subset of the origin namespace that has been accessed.
• B. The namespace of a FlexCache volume is identical to the origin's namespace.
• C. The FlexCache namespace is created independently and mapped manually.
• D. FlexCache always pre-populates the entire origin namespace during creation.

Answer: (A)

FlexCache works as a local caching layer for data from an origin, bringing data into the cache only when it’s actually accessed. That means the cache namespace holds just a subset of the origin namespace—the files and metadata that have been requested. It’s not a full, identical copy of the origin; the local view expands only with access, ensuring efficient use of cache space. The cache namespace is created and integrated as part of the FlexCache setup and is automatically tied to the origin, rather than being an independently created, manually mapped replica. It also doesn’t pre-populate the entire origin namespace at creation; items are cached on demand (or via explicit prefetch if configured), not upfront.
