220-1102 Practice Question: tracert/traceroute uses ICMP echo requests.

Answer choices

Why each option matters

Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.

Answer analysis

Why the other options are wrong

Understanding why incorrect options are tempting is as important as knowing the correct answer.

• ✗

  Event Viewer

  Event Viewer is useful for logs, but this scenario requires a different primary tool or control.

• ✗

  System Restore

  System Restore is useful for reversing certain Windows changes but is not the best fit for this specific goal.

• ✗

  Local Users and Groups

  Local user management does not directly address the stated issue.

How to think about this question

The `tracert` (Windows) or `traceroute` (Linux/macOS) command is an invaluable network diagnostic tool designed to map the path a packet takes from a source to a destination across an IP network. It operates by sending a sequence of Internet Control Message Protocol (ICMP) echo request packets, incrementing the Time-To-Live (TTL) value with each successive set of packets. Each router along the path that receives a packet with a TTL of 1 will decrement it to 0 and send an ICMP 'Time Exceeded' message back to the source. By analyzing these 'Time Exceeded' messages and the final ICMP echo reply from the destination, `tracert` can identify each hop (router) in the path and measure the round-trip time to each hop. This allows a technician to pinpoint exactly where excessive latency begins or where a connection failure occurs, making it the perfect tool for identifying the starting point of network path issues for the finance laptop. In this specific scenario, the goal is to identify where network path latency or failure *begins*. `tracert` directly addresses this by showing each router a packet traverses and the response time from each. If a particular hop shows significantly higher latency than previous hops, or if a hop fails to respond, it immediately indicates the problem's origin. In contrast, Event Viewer provides system logs but doesn't map network paths; System Restore reverts system changes but doesn't diagnose network connectivity; and Local Users and Groups manages local account permissions, which is unrelated to network path diagnostics.
