Question

Which tool is used for network scanning and discovering devices on a network in Linux?

Options

  • Anetstat
  • Btcpdump

Explanation

Nmap is a powerful open-source tool widely used for network discovery and security auditing on Linux and other operating systems.

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.
