A __________ is a free protocol analyzer software tool that can display unencrypted network traffic on a monitor screen.

• A. malware-analyzer
• B. spyware tracer
• C. server
• D. packet sniffer

Answer: (D)

A packet sniffer is a free protocol analyzer software tool that captures and displays network traffic in readable form on your monitor. It watches the data packets as they travel across a network, decodes the protocols in each packet, and shows the contents when the traffic isn’t encrypted. This makes it a go-to tool for diagnosing network problems and monitoring activity on a network. Malware analyzers focus on analyzing malicious software, spyware tracers track or detect spyware, and a server is a computer or program that provides services to others. None of these are specifically about capturing and displaying live network traffic like a packet sniffer.
