Which tool is used for network protocol analysis and packet sniffing with a three-pane packet browser?

• A. Wireshark
• B. MECM and ARAD
• C. Group Policy
• D. COOP

Answer: (A)

Wireshark is a network protocol analyzer designed to capture and inspect traffic in depth. It records packets as they traverse the network and lets you examine them protocol by protocol, which is essential for diagnosing issues, analyzing performance, and understanding traffic behavior. A key feature is the three-pane packet browser: the top pane shows a list of captured packets with summary information, the middle pane provides a detailed, hierarchical view of the selected packet’s protocol layers, and the bottom pane displays the raw bytes of that packet. This layout lets you quickly correlate what you see at a high level with the exact data on the wire, making it a powerful tool for packet sniffing and protocol analysis. The other items listed are not packet sniffers or protocol analyzers: they serve separate functions like system management, policy configuration, or continuity planning, and do not provide the detailed packet-level inspection that Wireshark offers.
