NSE 6 – FortiAuthenticator 6.1 — Question 13

You are a FortiAuthenticator administrator for a large organization. Users who are configured to use FortiToken 200 for two-factor authentication can no longer authenticate. You have verified that only the users with two-factor authentication are experiencing the issue.
What can cause this issue?

Answer options

• A. FortiAuthenticator has lost contact with the FortiToken Cloud servers
• B. Time drift between FortiAuthenticator and hardware tokens
• C. One of the FortiAuthenticator devices in the active-active cluster has failed
• D. FortiToken 200 license has expired

Correct answer: B

Explanation

The correct answer is B, as time drift between the FortiAuthenticator and the hardware tokens can lead to authentication failures, since the tokens rely on synchronized time to generate valid codes. Options A, C, and D are less likely causes in this scenario, as they would typically affect all users or indicate a different kind of failure unrelated to the specific two-factor authentication setup.
