Exam N10-008 topic 1 question 850 discussion

To validate if asymmetrical routing is causing the issue, the senior engineer should use traceroute on both the source and destination network devices. This command provides a path of the route packets take from one point to another. By running traceroute on both ends, the engineer can compare the routes and identify if packets are taking different paths, which would indicate asymmetrical routing. B. ping: This command is used to test connectivity and measure round-trip time but does not show the path taken by packets. C. route: This command shows the routing table of the device but does not provide information on the path packets take during transit. D. nslookup: This command is used to query DNS to obtain domain name or IP address mapping but does not provide information about the routing path.

A. traceroute. Traceroute is a diagnostic tool that tracks the path packets take from the source to the destination. By running traceroute on both the source and the destination devices, the engineer can compare the paths taken by the packets in each direction. If the paths differ significantly, this would indicate asymmetrical routing. B. Ping: This command tests connectivity between two devices by sending ICMP echo requests and measuring the round-trip time. However, it does not reveal the path taken by packets, so it is not useful for diagnosing asymmetrical routing. C. Route: This command displays the routing table on a device, showing the paths that packets should take to reach different networks. While it can show potential routes, it does not directly show the actual path that packets are taking, especially in a network with dynamic routing. D. nslookup: This command is used to query DNS servers to find the IP address associated with a domain name or vice versa. It is unrelated to routing and would not help diagnose asymmetrical routing issues. Thus, traceroute is the appropriate tool to use in this situation.

A is the answer
