- A
AWS Identity and Access Management (IAM) policies
Why wrong: IAM policies are attached to IAM users, groups, or roles within a single account. They cannot enforce restrictions across multiple accounts or prevent the root user from creating IAM users. They also do not apply automatically to new accounts added to the organization.
- B
AWS Organizations service control policies (SCPs)
SCPs are a centralized policy mechanism within AWS Organizations that can deny the IAM:CreateUser action across all member accounts in an organization, OU, or specific account. SCPs apply to all principals, including the root user, and affect both existing and future accounts, making them the correct choice for enforcing this restriction.
- C
AWS Config managed rules with automatic remediation
Why wrong: AWS Config rules can detect when an IAM user is created (non-compliant) and trigger automatic remediation actions, but they cannot prevent the creation in the first place. This is a detective and reactive solution, not a preventive one, and it requires per-account configuration.
- D
IAM Access Analyzer
Why wrong: IAM Access Analyzer is used to analyze resource-based policies (e.g., S3 bucket policies, IAM roles) to identify resources shared with external principals. It does not have the ability to enforce restrictions on the creation of IAM users.
CLF-C02 Security and Compliance Practice Question
This CLF-C02 practice question tests your understanding of security and compliance. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A company uses AWS Organizations to centrally manage multiple AWS accounts. The security team requires that no IAM users can be created in any member account. All access must use federated identities from the company's existing identity provider. The security team needs a single, centralized mechanism to enforce this restriction across all existing and future member accounts. Which AWS feature should the security team use to meet this requirement?
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 Organizations service control policies (SCPs)
AWS Organizations service control policies (SCPs) allow a central administrator to define maximum permissions for all accounts within an organization. By creating an SCP that explicitly denies the `iam:CreateUser` action, the security team can enforce that no IAM users can be created in any member account, including future accounts, because SCPs are inherited by all accounts in the organization. This provides a single, centralized mechanism that cannot be overridden by account-level IAM policies.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse SCPs with IAM policies, thinking IAM policies can centrally control all accounts, but SCPs are the only mechanism that can enforce restrictions across an entire AWS Organization, including preventing the creation of IAM users.
Detailed technical explanation
How to think about this question
SCPs are evaluated before IAM policies and can only deny or allow actions; they cannot grant permissions. An SCP with a Deny effect on `iam:CreateUser` will block the action even if an IAM policy in the member account allows it, because SCPs act as a guardrail. This is implemented via the AWS Organizations service, which applies the SCP to all accounts in the organization unit (OU) or the entire organization, ensuring future accounts automatically inherit the restriction.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
