What command is helpful for troubleshooting whether data packets are reaching their destination?

  1. traceroute

  2. ipconfig

  3. arp

  4. netstat

The correct answer is: traceroute

The command that is most helpful for troubleshooting whether data packets are reaching their destination is traceroute. This command is used to determine the path that packets take from the source to the destination, providing insight into each hop in the network process. It can help identify where in the route any issues may occur, such as delays, lost packets, or failed connections. Traceroute provides a detailed view of the network path, including the round-trip time for each segment, which can be crucial for diagnosing connectivity problems. The other commands serve different purposes: ipconfig is used for displaying network configuration settings, arp helps in mapping IP addresses to MAC addresses, and netstat is useful for monitoring active connections and network statistics. These tools are important for various aspects of network management but do not specifically trace the route taken by data packets or indicate whether packets are successfully reaching their destination.
