NO.1 A customer's application is stored on a DMX-4. The application runs 24x7x365. They would like to send
consistent replicas of this data simultaneously to four branch offices on a nightly basis. The branch offices
have CLARiiON arrays.
Which solution would you recommend?
A. Use TimeFinder/Mirror to create a consistent replica of the production application. Then use Open
Replicator cold push to replicate the data from the BCVs to the remote offices.
B. Use Open Replicator cold push to replicate the data to the remote offices.
C. Use Open Replicator hot push to replicate the data to the remote offices.
D. Use TimeFinder/Snap to create a consistent replica of the production application. Then use Open
Replicator cold push to replicate the data on the VDEVs to the remote offices.

COFW compared with TimeFinder/Clone with Enginuity 5772?
A. Back-end operations are lower with 5773 Enginuity.
B. Back-end operations are the same in both Enginuity versions.
C. Back-end operations are higher with 5773 Enginuity.
D. Depends on disk speed and RAID protection.
