Which tool is used to capture and interactively browse the traffic on a network?

• A. Nmap
• B. Wireshark
• C. Telnet
• D. Firmware Mod Kit

Answer: (B)

Network traffic capture and interactive inspection relies on a packet analyzer that can sniff data off an interface, decode many protocols, and let you inspect individual packets in real time. Wireshark does exactly this: it captures live traffic, decodes hundreds of protocols, and presents an interactive view with filters, coloring, and the ability to drill into a packet’s headers and payload. You can also follow a TCP stream to see a complete conversation, which is essential for diagnosing issues or analyzing malicious activity. Nmap scans networks to discover hosts and services, not to capture or inspect live traffic. Telnet is simply a remote login protocol, not a traffic analyzer. Firmware Mod Kit is used for unpacking and modifying firmware, not monitoring network traffic.
