Which command is used to show the path between source and destination in a TCP/IP network?

The command that shows the path between a source and destination in a TCP/IP network is the one that uses the method of tracing the route that packets take through the network. The correct answer leverages the functionality of ICMP (Internet Control Message Protocol) to send packets and receive back responses at each hop along the path.

This command outputs the addresses of each router that a packet is passed through, as well as the time it takes for packets to reach each one. This makes it a valuable tool for diagnosing network issues, determining the speed of connections, and understanding the topology of the network.

Other options do not serve this specific function. While one may think of the Ping command, it primarily tests connectivity to a specific host rather than detailing the network path taken. Similarly, Ipconfig and IFconfig are used for viewing and configuring network interface settings on Windows and Linux systems, respectively, but do not provide path information in a network. Thus, the chosen command is the most appropriate for tracing the route in a TCP/IP network.
