Explanation:
User1 will be required to register for MFA on the next sign-in: YesUser1 is a member of Group1, which is included in the MFA registration policy. Since User1 is not excluded, they will be required to register for MFA on the next sign-in.
User2 will be required to register for MFA on the next sign-in: NoUser2 is a member of both Group1 and Group2. Since Group2 is excluded from the MFA registration policy, User2 will not be required to register for MFA.
User3 will be required to register for MFA on the next sign-in: NoUser3 is a member of Group2, which is excluded from the MFA registration policy. Therefore, User3 will not be required to register for MFA.
