What happens if the MFA enrollment policy does not allow all user types?

When the MFA enrollment policy is configured to not include all user types, it specifically means that certain categories of users may be exempt from Multi-Factor Authentication (MFA) requirements. Hence, users who fall outside the defined parameters of that policy will not receive authentication challenges when they attempt to log in.

This situation leads to a scenario where some users can access resources without having to fulfill the MFA requirement, which maintains accessibility for them while potentially posing security risks if those users should have been subject to stricter authentication.

The other choices touch on different outcomes related to MFA, but they do not accurately represent the implications of an MFA enrollment policy that restricts its application to certain user types. While some options might suggest broader impacts or specific exclusions, the key detail is that the exclusion built into the policy directly influences who does and does not face the requirement to complete MFA.
