CompTIA A+ Core 2 (220-1102) — Question 648

A user is unable to access a website, which is widely used across the organization, and receives the following error message:

The security certificate presented by this website has expired or is not yet valid.

The technician confirms the website works when accessing it from another computer but not from the user's computer. Which of the following should the technician perform NEXT to troubleshoot the issue?

Answer options

• A. Reboot the computer.
• B. Reinstall the OS.
• C. Configure a static IP.
• D. Check the computer's date and time.

Correct answer: D

Explanation

The correct answer is D because an incorrect date and time on the user's computer can cause security certificate validation to fail. Options A and B are not relevant to the problem, and C does not address the certificate error, which is likely tied to the system's date and time settings.
