Question 17

In a network troubleshooting scenario, a network engineer is tasked with diagnosing connectivity issues between two remote offices. The engineer uses the `ping` command to check the reachability of a server in the remote office. After receiving a series of responses, the engineer then employs `traceroute` to analyze the path taken by packets to reach the server. However, the engineer notices that the `traceroute` command shows a significant delay at one of the hops, which is not present in the `ping` results. What could be the most likely explanation for this discrepancy in the results?

Accepted Answer

The hop with significant delay is likely a router that is configured to deprioritize ICMP packets, which are used by both `ping` and `traceroute`, leading to different response times.
