Explanation

Common mistakes.
- A. netstat displays network connections, routing tables, interface statistics, and masquerade connections, but is not primarily a network discovery or scanning tool.
- B. tcpdump is a packet analyzer that captures and displays network packets, primarily used for network monitoring and troubleshooting, not active device discovery.
- D. traceroute maps the path packets take to a network host, showing intermediate hops, but it does not perform broad network scanning or device discovery like Nmap.
