Which of the following allows two computers to coordinate in executing software?

A.
RSH

B.
RPC

C.
NFS

D.
SNMP

Explanation:
The programmer of a piece of software can write a function call that calls upon a subroutine. The subroutine
could be local to the system or be on a remote system. If the subroutine is on a remote system, it is a Remote
Procedure Call (RPC). The RPC request is carried over a session layer protocol. The result that the remote
system provides is then returned to the requesting system over the same session layer protocol. With RPC a
piece of software can execute components that reside on another system.Incorrect Answers:
A: The remote shell (rsh) is a command line computer program that can execute shell commands as another
user, and on another computer across a computer network. RSH is not used to remotely execute software.
C: The Network File System (NFS) is not used to execute software remotely. NFS is a client/server application
that lets a computer user view and optionally store and update file on a remote computer as though they were
on the user’s own computer.
D: SNMP is used for monitoring the network, not for remote software execution.
