Storage administrators for an EMC Symmetrix VMAX need to increase allocated storage for Microsoft Exchange LUNs without interrupting its operation. Performing a virtual LUN migration causes a critical nightly clone operation to run for hours instead of minutes. This impacts later dependent jobs, preventing production operations from completing.
How can this impact to the nightly process be minimized?

A.
Set a QoS value of 8 for MIR Copy Pace

B.
Set a QoS value of 0 for MIR Copy Pace

C.
Set SPC value of 1 on the Exchange LUNs

D.
Set SPC value of 8 on the clone LUNs
