What does flushing the cache do?

• A. Flushes the cache
• B. Deletes user accounts
• C. Clears all backups
• D. Rebuilds the index

Answer: (A)

Flushing the cache means clearing all the stored cached data so the next requests fetch fresh information from the original source. This removes stale or outdated content and can free up memory or storage used by the cache. After flushing, you might notice a slower first access as the system repopulates the cache with new data.

The other options describe actions that aren’t related to clearing cached data: deleting user accounts affects authentication data, clearing backups removes protection or restore points, and rebuilding the index updates search structures rather than clearing temporary cached results.
