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
✓
SAML-based federated authentication
AWS Client VPN supports SAML-based federated authentication, which can integrate with your corporate Active Directory to authenticate users. Option A is wrong because IAM authorization is not an authentication method for Client VPN; it is used for controlling access to AWS APIs. Option C is wrong because certificate-based authentication uses client certificates and does not directly tie to Active Directory user identities. Option D is wrong because mutual authentication still relies on certificates and does not inherently provide integration with Active Directory.
