Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
IAM policies
Why it's wrong here
IAM policies are attached to IAM users, groups, or roles within an account and cannot manage permissions across accounts centrally at the organization level.
- ✗
KMS key policies
Why it's wrong here
KMS key policies control access to encryption keys, not overall permissions to data lakes across accounts.
- ✗
S3 bucket policies
Why it's wrong here
S3 bucket policies are specific to individual S3 buckets and do not provide central management across all accounts.
- ✓
Service control policies (SCPs)
Why this is correct
Service control policies (SCPs) are used in AWS Organizations to centrally manage permissions and access across all member accounts, making them the correct choice.
