CompTIA A+ Core 2 (220-1202) — Question 3

MFA for a custom web application on a user's smartphone is no longer working. The last time the user remembered it working was before taking a vacation to another country. Which of the following should the technician do first?

Answer options

• A. Verify the date and time settings.
• B. Apply mobile OS patches.
• C. Uninstall and reinstall the application.
• D. Escalate to the website developer.

Correct answer: A

Explanation

The first step is to verify the date and time settings because incorrect settings can prevent MFA from functioning properly. If the date and time are incorrect, it could cause issues with authentication tokens. The other options may be relevant but are not the immediate step to troubleshoot this specific issue.
