Which command provides information about network configuration and active connections?

The correct answer is netstat. This command provides detailed information about network connections, including active connections to and from the computer, along with their respective states. It lists all open sockets and listening ports, as well as the corresponding protocol (TCP/UDP) in use. This is particularly useful for monitoring network activity, diagnosing network issues, and assessing security by identifying unexpected connections or services running on the system.

While other commands provide relevant information about network configuration, they focus on different aspects. For instance, ipconfig displays the IP configuration details of the network interfaces, including IP address, subnet mask, and default gateway, which is more about the settings rather than live connections. Tracert is used to trace the route packets take to a specific network destination, providing information about each hop along the route, but it does not give details on active connections. Nslookup is primarily used for querying DNS records and resolving domain names to IP addresses, which is important for network configuration but does not provide insights into current network connections. Thus, netstat is the most appropriate choice for obtaining information about active network connections.
