AWS SAA-C03 · Question 18 · Domain 1.1: Secure Access

A senior developer needs the ability to create new IAM roles for Lambda functions. However, the security team wants to ensure the developer cannot create roles with administrative privileges. How can this be enforced?

Answer options:

A.

Attach an IAM policy to the developer that explicitly denies the AdministratorAccess policy.

B.

Use an IAM permissions boundary to restrict the maximum permissions the developer can grant.

C.

Use AWS Organizations SCPs to restrict the developer's IAM user.

D.

Require MFA for all IAM role creation.

How to approach this question

When delegating IAM creation while restricting maximum permissions, use Permissions Boundaries.

Full Answer

B.Use an IAM permissions boundary to restrict the maximum permissions the developer can grant.✓ Correct
An IAM permissions boundary is an advanced feature that allows you to use a managed policy to set the maximum permissions that an identity-based policy can grant to an IAM entity. This safely allows developers to create roles without escalating privileges.

Common mistakes

Confusing SCPs (account level) with Permissions Boundaries (entity level).
