ABC.com has contacted EMC to solve its backup infrastructure problem. Its current backup
infrastructure consists of several different types of backup software and tape drives, dedicated to
its own servers. After several meetings you designed a centralized backup infrastructure,
implementing backup to disk technology. ABC.com is very concerned about disaster recovery
times. You propose one CX500 with ATA disks to be used onsite, at the primary location, and
another CX500 at a secondary location so backup data can be replicated from one CLARiiON to
the other one through the WAN. This will ensure that the backup data will be available in case of a
major disaster with the primary location. What other action should be taken?

A.
Set the backup software block size to match theCLARiiON stripe size

B.
Tune the backup software block size for remote replication

C.
Enable the write cache on the target CX500

D.
Replicate backup software catalog
