Which command lists wireless interfaces and configuration on a system?

• A. Nmap
• B. Airmon-ng
• C. Binwalk
• D. ifconfig

Answer: (D)

The main idea is to use a command that reports the system’s network interfaces and their configuration. The command that does this is ifconfig. It lists each interface by name (including wireless ones like wlan0 or wlp2s0) and shows its status and settings, such as the IPv4 address, netmask, broadcast address, and MAC address. This makes it easy to see which wireless interface exists on the system and what its current configuration is. The other tools have different purposes: Nmap is for scanning networks and hosts; Airmon-ng is for enabling or managing monitor mode on wireless interfaces; Binwalk analyzes firmware. On newer systems you might use ip addr show, but ifconfig remains the classic way to list interfaces and their configuration.
