What is a key difference between SRDF/Metro and SRDF/S?

A. SRDF/Metro: R1 devise is host accessible, R2 is red-only SRDF/S: R1 is host accessible, R2 is write disabled

B. SRDF/Metro: R1 and R2 devices are host accessible at the same time SRDF/S: R1 devices are host accessible, R2 devices are write disabled

C. SRDF/Metro: R2 can be larger than R1 SRDF/S R2 cannot be larger than R1

D. SRDF/Metro: Requires a third array for any witness functionality SRDF/S: Does not require a third array

SRDF/Metro has been deployed between two data centers. SRDF/Metro is operating normally. Maintenance tasks at the R1 data center require the array to be offline.

A. Failover

B. Split with bias set to R2

C. Suspend with bias set to R2

D. Swap
