NO.5 A customer has two TS7740 V07 at Release 3 in a two-way grid across two sites. There is a new
requirement for a subset of the data created in Site A (Cluster 0) to be written in both sites but to
be in Site B (Cluster 1) at the end of the job.
What method is best employed to achieve this with the least impact on the batch run, and at the
lowest cost?
A. Setup a policy for the data creating a copy consistency of RR in Site A
B. Setup a policy for the data creating a copy consistency of RD in Site A
C. Set up a policy for the data creating a copy consistency of DR in Site A
D. Connect Site A to the TS7740 in Site B with two PICON channels and run the jobs using logical
units on Site B
Answer: C
