What are two [2] features of a snapshot?

A.
A full copy of data in a source LUN

B.
Can be created or destroyed in seconds

C.
A point-in time “virtual” copy that does not occupy any disk space

D.
Cache LUN generally requires approximately 10% to 30% of the source LUN size

Explanation:
While a snapshot is a point-in-time “virtual” copy, it does take up space on snap cache luns for any data that has changed since the snap session was created. Typically starting parameters are to create snap cache luns that are 10% to 30% of the source lun size, the need will depend upon how much data is actually changing.
