1. An enterprise wants centralized, federated workforce access to all its AWS accounts using existing corporate identities (via SAML), with permission sets mapped to roles. Which service should the architect recommend?
- A. AWS IAM Identity Center (successor to AWS SSO)✓ Correct
- B. Creating IAM users in every account
- C. Sharing root credentials
- D. Amazon Cognito user pools for employees
Explanation
IAM Identity Center provides centralized, federated single sign-on to multiple accounts with permission sets, integrating corporate identity providers via SAML. Per-account IAM users (B) don't scale and fragment identity, sharing root (C) is a severe risk, and Cognito (D) targets application end users, not workforce SSO to accounts.
