A person is troubleshooting a network issue and needs to view all active connections and listening ports. Which Windows command should be used?

Rationale

netstat -an is the command used to view all active connections and listening ports in Windows.

The netstat command provides detailed information about network connections, including active TCP connections and their respective listening ports, making it essential for network troubleshooting.

A (tracert) YOUR ANSWER

The tracert command is used to trace the route that packets take from one host to another over a network. It shows the path and measures transit delays of packets across an IP network but does not provide details about active connections or listening ports.

B (arp -a) YOUR ANSWER

The arp -a command displays the Address Resolution Protocol (ARP) table, which maps IP addresses to MAC addresses on a local network. While useful for understanding network mapping, it does not show active connections or listening ports.

C (netstat -an) CORRECT

This command is specifically designed to display all active connections and listening ports on a Windows machine. It provides comprehensive details concerning the status of TCP and UDP connections, along with the local and remote IP addresses and port numbers.

D (ipconfig) YOUR ANSWER

The ipconfig command is used to display and manage the IP configuration settings of a Windows machine, including the IP address, subnet mask, and default gateway. While it provides essential information about the network interface, it does not show active connections or listening ports.

Conclusion

When troubleshooting network issues, viewing active connections and listening ports is crucial. The netstat -an command offers a complete overview of these elements, thereby assisting network administrators in diagnosing and resolving connectivity problems effectively. Other commands like tracert, arp -a, and ipconfig provide different types of information that do not directly address the need for active connection and port listening details.
