Topic #: 4
A technician is troubleshooting internet connectivity issues after a firewall update. Users report that they can access local network resources, such as printers and shares, but cannot access the internet. Which of the following settings is most likely causing the issue?
Suggested Answer: B Vote an answer
Comprehensive and Detailed In-Depth Explanation:
If users can access local network resources but not the internet, the most likely culprit is a misconfigured or missing default gateway. The default gateway routes traffic from the local network to external networks (i.
e., the internet). If it's not properly set or was altered during a firewall update, internet traffic won't be forwarded correctly.
* Option A: Static IPs could cause conflict, but wouldn't affect only external access if configured correctly.
* Option C: An incorrect subnet mask could isolate devices, but local communication would likely be impacted too.
* Option D: VLANs segment networks; while misconfigured VLANs could cause access issues, they'd more likely isolate local traffic as well.

* Objective 2.6: Given a scenario, configure and troubleshoot network connectivity.
