CoreIAM
Password, MFA, roles, federation, policies, conditions, and access troubleshooting.
Key points
- IAM authorization can involve identity, resource, trust, session, boundary, and Organizations policy layers plus request conditions.
Best-known use cases
- D4.1, D4.2, and D5.1: diagnose or correct the named authentication or authorization decision at its actual policy boundary.
What candidates often confuse it with
- IAM policies grant within applicable limits; SCPs and permissions boundaries cap access, and explicit deny takes precedence.
Key takeaway
Start with the exact principal, action, resource, Region, and context before adding an allow.
