CompTIA A+ Core 1 (220-1201) — Question 36

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?

Answer options

• A. Static IP assignments
• B. Default gateway
• C. Subnet mask
• D. VLANs

Correct answer: B

Explanation

The default gateway is essential for routing traffic from the local network to the internet. If this setting is incorrect or missing, users will be able to access local resources but not external internet sites. The other options, such as static IP assignments, subnet mask, and VLANs, do not directly impact the ability to reach the internet in this scenario.
