A _____ is a networking tool that monitors and intercepts traffic over a computer network.

• A. Packet Analyzer
• B. Router
• C. Switch
• D. Firewall

Answer: (A)

Packet analyzer is the best fit. It captures and analyzes the data packets moving across a network, allowing you to monitor traffic, inspect headers and payloads, and troubleshoot or study network behavior. This matches the idea of monitoring and intercepting traffic for analysis. A router’s job is to forward packets between different networks, not primarily to observe or inspect traffic. A switch sends frames within a local network based on MAC addresses, focusing on delivering data to the correct device. A firewall sits between networks to block or allow traffic according to security rules, rather than continuously monitoring and analyzing all traffic for visibility.
