Which utility is used to capture and analyze traffic for ARP poisoning in these labs?

• A. Wireshark
• B. Nessus
• C. Nmap
• D. Metasploit

Answer: (A)

Capturing and analyzing traffic to spot ARP poisoning relies on observing ARP activity on the network. Wireshark is a packet capture and protocol analysis tool that lets you see every ARP request and reply, decode the ARP frames, and filter to focus on ARP traffic. In an ARP spoofing scenario, you’d look for signs like ARP replies that associate a different MAC address with a given IP, multiple ARP responses for the same IP from different devices, or unsolicited ARP announcements. By filtering for ARP and inspecting who is claiming ownership of which IPs, you can detect inconsistencies that indicate poisoning. The other tools shown aren’t designed for this kind of traffic capture and ARP analysis: Nessus is a vulnerability scanner, Nmap is used for network discovery and port scanning, and Metasploit is an exploitation framework. This makes Wireshark the best choice for examining traffic to identify ARP poisoning in these labs.
