100-150 Question 224
Single answerA user reports they cannot access a website, and you are tasked with troubleshooting the issue. You decide to run the ping and tracert (or traceroute) commands. After running ping, you see responses from the IP address of the website, but the tracert command shows a timeout after reaching a specific router. What is the most likely cause of the issue?
- A
The user's local device has a misconfigured IP address.
- B
A network firewall is blocking traffic to the website at an intermediate hop.
- C
The DNS server is unable to resolve the website's domain name.
- D
The website's server is down and not responding to requests.
Show answer and explanation
Correct answer: B
Explanation
In this scenario, the ping command confirms that the website's IP can be reached, ruling out issues with the device's IP configuration or server downtime. The tracert command showing a timeout at a specific router indicates that packets are not being forwarded beyond that point. This suggests a network firewall or filtering issue at that specific hop, making Option 2 the correct answer.
- A. Incorrect.
If the user's local device had a misconfigured IP address, the
pingcommand would fail entirely, as there would be no connectivity to the network. - B. Correct.
A network firewall blocking traffic at an intermediate hop is the most likely cause. The
pingresponse confirms that the website's IP is reachable, but thetracerttimeout at a specific hop indicates an issue with packet forwarding or filtering at that point. - C. Incorrect.
If the DNS server was unable to resolve the domain name, the
pingcommand would fail when using the domain name. However, in this scenario, the IP address is already being used successfully. - D. Incorrect.
If the website's server was down, the
pingcommand would fail, as the server would not respond. Thetracertwould also likely fail entirely.
