What is the effect of flushing the cache?

• A. Rebuilds the index
• B. Deletes backups
• C. Flushes the cache
• D. Resets user permissions

Answer: (C)

Flushing the cache means clearing the cached data so future requests fetch fresh data from the original sources rather than from stored temporary copies. This helps remove stale content and ensures users see the most up-to-date information, which can also resolve display or performance issues caused by outdated cached data. It doesn’t rebuild an index, delete backups, or reset user permissions—those are separate maintenance actions. Rebuilding an index optimizes search structures, deleting backups removes recovery points, and resetting user permissions changes access rights.
