Which command-line tool can be used to query the RPC portmapper?

nc
rpcinfo
curl
wget

The correct answer is: rpcinfo

The command-line tool that can be used to query the RPC portmapper is rpcinfo. This tool is specifically designed to communicate with the Remote Procedure Call (RPC) protocol and allows users to obtain information about the RPC services that are available on a machine. When invoking rpcinfo, users can list the RPC services, get versioning information, and perform checks on what programs are currently registered with the portmapper. In the context of network security, understanding how to use rpcinfo is crucial because it helps assess the services running on a system and can assist in identifying potential vulnerabilities associated with exposed RPC services. This makes it an essential tool for security analysts who need to evaluate the security posture of systems and network services.
