Which tool would you use to visualize the path taken by packets to a destination, showing each intermediate router (hop)?

• A. Nslookup
• B. Netstat
• C. Traceroute/Tracert
• D. Ping

Answer: (C)

This question tests the ability to map the route packets take to a destination, showing each hop along the way. A traceroute (tracert on Windows) does this by sending probes with gradually increasing time-to-live (TTL) values. Each router along the path decrements TTL; when TTL reaches zero, that router sends back an ICMP Time Exceeded message, revealing its address. By collecting these responses from successive hops, you get a list of every router the packets pass through and, often, the time it takes to reach each one. This makes it ideal for visualizing the actual path to a destination and identifying where delays or failures occur along the route. In contrast, nslookup is for converting domain names to IP addresses and doesn’t show the path to the destination. Netstat displays active network connections and listening ports, not the route or hops to a destination. Ping checks whether a host is reachable and measures round-trip time to that host, but it does not reveal the intermediate routers or the route.
