How could you bypass the need for two-factor authentication for users accessing form specific secured networks?

You have implemented two-factor authentication to enhance security to sensitive enterprise systems.

How could you bypass the need for two-factor authentication for users accessing form specific secured networks?
A . Create an admin realm in the authentication policy
B. Specify the appropriate RADIUS clients in the authentication policy
C. Enable Adaptive Authentication in the portal policy
D. Enable the Resolve user geolocation from their IP address option in the authentication policy.

Answer: C

Explanation:

Adaptive Authentication is a feature that allows administrators to bypass the need for two-factor authentication for users accessing from specific secured networks. Adaptive Authentication uses geolocation information from IP addresses to determine whether a user is accessing from a trusted network or not. If the user is accessing from a trusted network, FortiAuthenticator can skip the second factor of authentication and grant access based on the first factor only.
