Which tool provides a real-time traffic analyzer per interface?

• A. Traceroute
• B. Torch
• C. Bandwidth Test
• D. Packet Sniffer

Answer: (B)

Torch provides a live, per-interface view of network traffic, showing real-time activity on a selected interface with details like source, destination, protocol, and port. This makes it ideal for quickly seeing what’s flowing through that interface right now, which is exactly what a real-time per-interface traffic analyzer does. Traceroute, on the other hand, maps the path to a destination and measures hop latencies, not the ongoing traffic on a specific interface. Bandwidth Test is designed to measure end-to-end throughput between two points, not provide ongoing per-interface traffic monitoring. A Packet Sniffer captures packets for later analysis or deeper inspection, which is useful for detailed content analysis but not the same as a live traffic summary per interface.
