Which protocol is typically used for remote job entry (RJE)?

Port 1
Port 5
Port 7
Port 20

The correct answer is: Port 5

The protocol typically used for remote job entry (RJE) is associated with port 5. RJE is a method that allows users to submit jobs to a remote computer system for processing. Traditionally, job entries are transmitted to a secure and designated service on the receiving machine. Port 5, specifically associated with the Remote Job Entry Protocol, facilitates the communication needed for sending job control commands and data to the mainframe or server to be processed. Understanding the correct port is vital for ensuring that remote job entry operations can function properly, given that communication over the right path is essential for job management and execution. The other options do not relate to the standard protocol for remote job entry. Each port corresponds to different services that are not designed or used for managing jobs in a remote computing environment.
