A Symmetrix is configured with the two RDF Groups RDFG 1 and RDFG 2 as shown in the exhibit.

The SRDF R1 devices used by Application 1 (App 1) and Application 2 (App 2) are in RDFG 1.
The SRDF R1 devices used by Application 3 are in RDFG 2.
Application 3 is independent of Applications 1 and 2. What is required to replicate these
applications in SRDF/A?

A.
One device group with all the devices in RDFG 1 and RDFG 2

B.
Two device groups; one with all the devices in RDFG 1 and another with all the devices in
RDFG 2

C.
Three device groups; one with the App 1 devices, a second with the App 2 devices, and a third
with the App 3 devices

D.
Three files; one with the App 1 devices, a second with the App 2 devices, and a third with the
App 3 devices
