A customer has an ERP system protected by SRDF/A and experienced a loss of link for 6 hours due to a network issue. When the network issue was fixed the links came back up and SRDF was resumed.
Prior to SRDF/A resuming cycle switching, there was a disaster at the source site, rendering the R1 array unusable. The ERP system was not startable at the DR site and the customer had to restore from tape.
What would prevent this from happening in the future?

A.
Implement clones on the target side and split them prior to resuming SRDF after a network outage

B.
Implement clones with TimeFinder Consistency Groups on the source side and split them prior to resuming SRDF after a network outage

C.
Implement snaps on the target side and split prior to resuming SRDF after a network outage

D.
Use Consistency Groups and set SRDF QoS to 0
