Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use SAML-based federation with an identity provider that requires MFA
AWS Client VPN supports SAML-based federation with an identity provider (IdP) that requires MFA, making option D correct. Option A is incorrect because security groups do not enforce authentication, let alone MFA. Option B is incorrect because using AWS Managed Microsoft AD alone does not enforce MFA; MFA would require additional configuration such as AWS AD Connector or a third-party MFA solution. Option C is incorrect because mutual authentication with client certificates verifies the client's identity but does not enforce MFA.
