Which two events occur during the time that the snapvault start command is creating a backup relationship between a primary and secondary storage system? (Choose two.)

A.
The secondary storage system requests an initial baseline transfer of the qtree or volume data from the primary volume.

B.
The primary storage system creates a Snapshot copy of the volume identified in the snapvault start command.

C.
The qtree data that has recently changed is transferred from the primary Snapshot copy to the baseline SnapVault secondary volume.

D.
The baseline SnapVault copy is processed on the primary by creating a new Snapshot copy and comparing it with the previous regularly
scheduled Snapshot copy to determine which data blocks need to be replicated.
