Remote Procedure Call (RPC) is a protocol that one program can use to request a service from a program located in another computer in a network.  Within which
OSI/ISO layer is RPC implemented?

A. Session layer

B. Transport layer

C. Data link layer

D. Network layer








 

Suggested Answer: The Answer: Session layer, which establishes, maintains and manages sessions and synchronization of data flow.  Session layer protocols control application-to-

Community Answer: B

application communications, which is what an RPC call is.
The following answers are incorrect:
Transport layer: The Transport layer handles computer-to computer communications, rather than application-to-application communications like RPC.
Data link Layer: The Data Link layer protocols can be divided into either Logical Link Control (LLC) or Media Access Control (MAC) sublayers.  Protocols like
SLIP, PPP, RARP and L2TP are at this layer.  An application-to-application protocol like RPC would not be addressed at this layer.
Network layer:  The Network Layer is mostly concerned with routing and addressing of information, not application-to-application communication calls such as an
RPC call.
