CompTIA A+ Core 2 (220-1102) — Question 26

While browsing a website, a staff member received a message that the website could not be trusted. Shortly afterward, several other colleagues reported the same issue across numerous other websites. Remote users who were not connected to corporate resources did not have any issues. Which of the following is
MOST likely the cause of this issue?

Answer options

• A. A bad antivirus signature update was installed.
• B. A router was misconfigured and was blocking traffic.
• C. An upstream internet service provider was flapping.
• D. The time or date was not in sync with the website.

Correct answer: D

Explanation

The correct answer is D because if the time or date on a user's device is not synchronized, it can lead to SSL certificate validation issues, causing trust warnings. Options A, B, and C are less likely because they would not typically cause trust messages to appear for multiple users simultaneously on different websites.
