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
✓
AWS IAM Identity Center (AWS Single Sign-On)
AWS IAM Identity Center (formerly AWS Single Sign-On) enables centralized management of permissions across multiple AWS accounts by allowing administrators to define fine-grained permissions using permission sets. This eliminates the need to create individual IAM users in each account. Option A is incorrect because IAM is per-account and does not support cross-account permission management without additional configuration. Option C is incorrect because AWS Resource Access Manager (RAM) is used to share resources, not to define permissions. Option D is incorrect because AWS Key Management Service (KMS) is for encryption key management, not access control.
