Query on LSA (7.1) Quiz - Caching

One of the question in caching quiz is as mentioned below.

Can anyone explain why option one i.e. "Whenever cache hit is returned, the system does not invoke the database." is incorrect. If the rule instance is found in the cache, why it would query in the database again?

Regards,

Sandeep

To me, Cache can be invalidated (System Pulse in multi nodes) or expired and so it will need to get to DB again then cache it again.

A particular entry will be in probationary state, until its invoked multiple times (3 to 4 times). So, it may be in the cache but its not marked ready to be returned.
