Which command would you use on Windows to view listening ports and current TCP connections?

• A. netstat -ano Windows
• B. netstat -tunp on Linux
• C. ss -tuln
• D. lsof -i

Answer: (A)

To view listening ports and current TCP connections on Windows, use netstat with -ano. The -a option shows all sockets, including both listening ports and established connections; -n displays addresses and ports numerically so you get exact numbers without DNS lookups; -o adds the owning process ID for each socket, so you can identify which program is using a given port. This combination gives you a complete, actionable snapshot of network activity and which process is tied to each port. The other commands are Linux/Unix-oriented (different flag syntax and not Windows-native), so they wouldn’t be appropriate for this Windows task.
