When a server profile for an organization is being established, which element describes the TCP and UDP daemons and ports that are allowed to be open on the server?

A server profile will often contain the following: Listening ports – the TCP and UDP daemons and ports that are allowed to be open on the server
User accounts – the parameters defining user access and behavior
Service accounts – the definitions of the type of service that an application is allowed to run on a server
Software environment – the tasks, processes, and applications that are permitted to run on the server
