What happens if the origin volume in a FlexCache relationship becomes temporarily unavailable?

• A. FlexCache volumes immediately become read-write.
• B. FlexCache volumes can continue to serve cached data until the origin becomes available again.
• C. All cached data is purged automatically.
• D. FlexCache volumes fail over and become the new origin.

Answer: (B)

When the origin volume is temporarily unavailable in a FlexCache relationship, the local cache can still serve data that has already been cached. This keeps reads fast and available for items that exist in the cache, even though the origin can’t be reached at that moment. If a request is for data not yet cached, it can’t be fulfilled until the origin returns. Once the origin becomes available again, normal operation resumes and the cache can repopulate as needed.
