Which statement best describes what mtr does?

• A. Only sends pings to check availability.
• B. Performs a tracepath to determine MTU.
• C. Combines ping and traceroute to show loss and latency per hop.
• D. Measures Wi-Fi signal strength and noise.

Answer: (C)

mtr merges the ideas of traceroute and ping into a live diagnostic tool. It continuously sends probes toward the destination and to each router along the path, so you can see how long replies take and whether packets are being lost at each hop. The result is an updating view of latency and packet loss per hop, which helps you pinpoint where problems occur—whether on a specific link, at a particular router, or closer to the source. It’s not just a simple ping test, nor a one-shot trace; it combines both to give real-time performance details. It doesn’t measure Wi‑Fi signal strength or MTU, so those aren’t what you’re examining with mtr.
