Which statement accurately describes how writes are handled on a FlexCache volume?

• A. Writes are stored in the cache and written locally to the cache only.
• B. Writes to a FlexCache volume are redirected and processed by the origin volume.
• C. FlexCache volumes cannot process any writes.
• D. Writes are kept in the cache and synchronized later.

Answer: (B)

FlexCache places a local cache in front of an origin volume, with the origin holding the authoritative copy of the data. When a write targets a FlexCache volume, that write is redirected to the origin and processed there. The origin updates its data, and the cache is refreshed to reflect the new state. This write-through behavior ensures durability and consistency across the system, so data isn’t kept only in the cache. Keeping writes only in the cache or delaying synchronization could lead to data loss or stale data on the cache, which is why those approaches aren’t how FlexCache handles writes.
