You have three RDF subsystems running on your primary, replicating the data to three different
backup systems, as follows:
RDF#1 \\a———————-> \\x
RDF#2 \\a———————-> \\y
RDF#3 \\a———————-> \\z
Which RDF subsystems can provide you with Process Lockstep?

A.
All three can provide Process Lockstep.

B.
Only two can provide Process Lockstep with your current Lockstep Gateway; if you need the
third RDF subsystem to provide Process Lockstep, you need to start a second Lockstep
Gateway.

C.
Only one can provide Process Lockstep with your current Lockstep Gateway, but all three can
provide it if you start a Lockstep Gateway for each RDF subsystem.

D.
Only one can provide Process Lockstep with your Lockstep Gateway.
