An EMC NetWorker customer has an Oracle database client. To achieve acceptable backup
performance, they have configured the backup to use multiple RMAN channels. The
customer wants to add EMC Avamar deduplication for this backup. What is a consideration
before proposing this design change?

A.
Multiple cache files are created on the client when using multiple channels

B.
Data from each RMAN channel must be sent to a separate deduplication node

C.
More than 2 RMAN channels in a deduplicated backup will cause the backup to fail

D.
Less than 4 RMAN channels in a deduplicated backup will perform poorly
