CompTIA A+ Core 2 (220-1102) — Question 495

A user is unable to access the internet but can still print to network printers. Other users are not experiencing this issue. Which of the following steps should the technician take first to diagnose the issue?

Answer options

• A. Validate physical connectivity.
• B. Reboot the router.
• C. Disable IPv6.
• D. Check the DNS settings.

Correct answer: D

Explanation

The correct first step is to check the DNS settings, as improper DNS configurations can prevent internet access while still allowing local network functionalities like printing. Validating physical connectivity, rebooting the router, and disabling IPv6 may not directly address the DNS issue, which is likely the root of the user's internet access problem.
