Multiple Choice

A ________ port number designates a specific application running on a server.

Explanation:
Ports let a host run multiple network services. Well-known ports (0–1023) are assigned to specific server applications, so traffic directed to one of these ports indicates the corresponding service will handle it (for example, HTTP on 80, SSH on 22). Ephemeral ports (1024–65535) are temporary source ports used by clients for outgoing connections and are not tied to a particular server application. Hence, the statement points to well-known port numbers as designating a specific application on the server.
