Which command scans all the nearby wireless networks?

• A. Nmap
• B. Airodump-ng
• C. Telnet
• D. Binwalk

Answer: (B)

Scanning for nearby wireless networks is about listing access points that are visible to your wireless adapter. Airodump-ng is the tool designed for that task. It is part of the aircrack-ng suite and runs in monitor mode to passively listen for beacon frames from access points across channels, collecting SSID, BSSID, channel, encryption type, and signal strength. It outputs a live inventory of all nearby networks, which matches what the question describes. The other options don’t provide this kind of wireless discovery: Nmap is a general-purpose scanner for IP networks, Telnet is a protocol for remote login, and Binwalk analyzes firmware images. Therefore, this wireless-network scanning tool is the appropriate choice.
