Exam N10-008 topic 1 question 843 discussion

The route command is the most appropriate choice for checking if traffic is using a newly added route. It allows the network engineer to view the current routing table, which will show whether the new route has been added and is being utilized. A. ping: This command tests connectivity to a specific IP address but does not provide information about the routing table or whether a specific route is being used. B. arp: This command displays the Address Resolution Protocol (ARP) table, which maps IP addresses to MAC addresses. It does not provide routing information. C. trace: The trace (or traceroute) command helps in identifying the path packets take to reach a destination, but it does not directly show routing table information.

C. trace The trace command, commonly known as traceroute, is used to trace the path that packets take from the source to the destination. By running a traceroute to a destination that should be using the new route, the engineer can see the actual path the packets are taking and verify if they are following the intended new route. ping is useful for checking basic connectivity but does not provide information about the path the traffic takes. arp is used for mapping IP addresses to MAC addresses, which is not relevant to checking the path of traffic. route shows the current routing table, but it does not confirm if traffic is actually using a specific route.
