The SCWCD exam is just about servets and

SCJP exam first, version 1.2, 1.3 or 1.4, otherwise Sun won't even let you sit for any of the other exams either.
Officially, there is no RPC in
Java; you probably mean RMI (Remote Method Invocation), which is Java's answer to Remote Procedure Calls. The SCBCD exam (mostly questions on
EJB), does use RMI over IIOP as its network backbone, so for the SCBCD exam, you will need to become familiar with RMI.
Good luck,
