A multinational company operates in multiple AWS Regions. The company must ensure that its developers and administrators have secure, role-based access to AWS resources.

The roles must be specific to each user's geographic location and job responsibilities.

The company wants to implement a solution to ensure that each team can access only resources within the team's Region. The company wants to use its existing directory service to manage user access. The existing directory service organizes users into roles based on location. The system must be capable of integrating seamlessly with multi-factor authentication (MFA).

Which solution will meet these requirements?
