Which of the following is NOT a function of the Remote Procedure Call (RPC)?

The function of a Remote Procedure Call (RPC) primarily revolves around enabling communication between software applications across a network. RPCs allow programs to execute procedures on a remote system as if they were local, facilitating both the execution of code on remote machines and enabling different applications to communicate effectively.

Options related to executing code on remote systems and facilitating inter-application communication are intrinsic to the design and function of RPC. Network management operations may also leverage RPCs for sending commands and receiving responses over the network, thus aligning with the protocol's capabilities.

However, user authentication is not within the scope of what RPC is designed to handle. While RPC can enable the transport of authentication credentials and may be used in conjunction with secure protocols to ensure user identity, it does not inherently provide mechanisms for authenticating users securely. Authentication typically involves separate protocols and processes that are specialized for that purpose, making it distinct from the core functionalities provided by RPC.
