NetApp storage is used as a networkmapped drive for a user’s home directory, and a scheduled Snapshot occurs. Afterwards, the user opens a file named netapp.dat that contains three data blocks: A, B, and C.

The user modifies the last block in the file, then saves it as C’, so that the updated file consists of blocks A, B and C’. A second Snapshot then occurs.

Which allocated blocks related to netapp.dat are referred to by the second Snapshot?

A.
C

B.
A, B, C’

C.
