Several RDF groups in a Symmetrix have been configured for SRDF/A. The SRDF/A sessions are independent of one another. The customer is concerned about the system hitting the cache write pending limit, causing SRDF/A sessions to become inactive.
What can help to ensure that the most critical RDF group does not get dropped?

A.
Set the minimum cycle time of the group to be higher than the others

B.
Set the session priority of the group to be a higher value than the others

C.
Set the minimum cycle time of the group to be lower than the others

D.
Set the session priority of the group to be a lower value than the others
