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

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

B.
Less than six RMAN channels in a deduplicated backup will perform poorly

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

D.
Separate cache files are recommended for each RMAN channel
