NSE 7 – OT Security 7.2 — Question 7

An OT administrator has configured FSSO and local firewall authentication. A user who is part of a user group is not prompted for credentials during authentication.
What is a possible reason?

Answer options

• A. Two-factor authentication is not configured with the RADIUS authentication method.
• B. The user was determined by the Security Fabric.
• C. FortiGate determined the user by passive authentication.
• D. FortiNAC determined the user by the DHCP fingerprint method.

Correct answer: C

Explanation

The correct answer is C because FortiGate can use passive authentication to recognize users without prompting for credentials if they are already authenticated through other means. Options A, B, and D are incorrect because they do not directly explain the lack of a credential prompt in this scenario.
