Which command line tool shows TCP connections, routing tables, and interface information?

• A. Netstat
• B. Ipconfig
• C. Tracert
• D. Ping

Answer: (A)

Netstat provides a snapshot of a host’s current network state by presenting active TCP connections, the routing table, and interface statistics in one tool. It pulls data from the kernel’s networking stack and formats it for easy viewing. The TCP connections portion shows which sockets are established or listening, so you can see which applications are talking to which endpoints. The routing table part reveals how the system forwards packets, including destination networks and next hops, which helps you understand reachability and path decisions. The interface information part gives per‑interface counters and statuses, such as traffic in and out and any errors. You can tailor the view with options to focus on connections, routes, or interfaces, but the core idea is that this single command exposes all three areas. The other commands mentioned are more specialized: ipconfig shows IP configuration, tracert traces the path to a destination, and ping tests reachability, none of which combine these three views.
