To verify the route to a distant host and see each hop in the path, which tool would you run?

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

Answer: (A)

Path tracing reveals the route to a distant host by showing each router the packets pass through. Traceroute does this by sending probe packets with a small TTL (time to live) value and then increasing it. Each router along the path decrements TTL; when it hits zero, the router sends back a reply, letting you record the hop’s address and the time it took. By collecting these responses, you get a hop-by-hop map of the route to the destination and can spot where delays or failures occur. The other tools don’t map the path: Torch focuses on real-time traffic on a local link, Bandwidth Test measures throughput to a remote endpoint, and Packet Sniffer captures traffic on a network segment. So traceroute is the tool that verifies the route and shows every hop in the path.
