Which utility displays TCP/IP specific protocol and interface statistics?

The utility that displays TCP/IP specific protocol and interface statistics is Netstat. This command-line tool provides a wealth of information about network connections, including active connections, routing tables, and a variety of protocol statistics related to TCP/IP. It can show which ports are open and what connections are established, along with the transmission control statistics that help diagnose network issues. By analyzing this data, network administrators are able to monitor the health and performance of the network, troubleshoot connectivity problems, and identify any abnormal activity.

The other options serve different purposes: Ping is designed to check the accessibility of a host by sending echo requests and measuring response times, Traceroute is used to trace the route packets take to reach a destination and identify each hop along the way, and FTP is a specific protocol used for transferring files over a network but does not provide statistics or insights into TCP/IP protocols or interface performance. Hence, Netstat stands out as the correct choice for displaying TCP/IP statistics directly.
