- A
Configure IAM policies in each account to deny these actions
Why wrong: IAM policies in individual accounts could be removed by the account's root user or admin — they don't provide organization-level enforcement.
- B
Apply Service Control Policies (SCPs) at the organization level
SCPs applied at the root or OU level create a permission boundary that applies to all member accounts — even root users in member accounts cannot perform actions denied by SCPs.
- C
Use AWS Config rules to detect and alert on violations
Why wrong: Config rules detect violations after they occur but don't prevent the action. SCPs prevent the action proactively.
- D
Enable MFA delete on all accounts
Why wrong: MFA delete applies specifically to S3 object deletion, not to disabling CloudTrail or Config.
Quick Answer
The answer is to apply Service Control Policies (SCPs) at the organization level. SCPs are the most effective way to prevent disabling CloudTrail and AWS Config across accounts because they act as centralized guardrails that cannot be overridden by any IAM policy within a member account, even by an account administrator. On the AWS Certified Cloud Practitioner CLF-C02 exam, this question tests your understanding of how AWS Organizations enforces security baselines; a common trap is confusing SCPs with IAM policies or AWS Config rules, but remember that SCPs deny actions at the root, OU, or account level before any IAM evaluation occurs. To lock down security services across all accounts, think of SCPs as the immutable “constitution” that overrides local “laws.” Memory tip: SCP stands for “Supreme Control Policy” — once applied, no one below can turn off the lights.
CLF-C02 Billing, Pricing, and Support Practice Question
This CLF-C02 practice question tests your understanding of billing, pricing, and support. 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. They want to ensure that member accounts cannot turn off CloudTrail or AWS Config in their accounts. What is the most effective way to enforce this?

Correct answer & explanation
Apply Service Control Policies (SCPs) at the organization level
Service Control Policies (SCPs) are the most effective way to enforce guardrails across all member accounts in AWS Organizations. SCPs can deny the ability to disable CloudTrail or AWS Config at the organization, organizational unit (OU), or account level, and they cannot be overridden by IAM policies in member accounts. This ensures that even account administrators cannot turn off these services, providing a centralized security control.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

- ✗
Configure IAM policies in each account to deny these actions
Why it's wrong here
IAM policies in individual accounts could be removed by the account's root user or admin — they don't provide organization-level enforcement.
- ✓
Apply Service Control Policies (SCPs) at the organization level
Why this is correct
SCPs applied at the root or OU level create a permission boundary that applies to all member accounts — even root users in member accounts cannot perform actions denied by SCPs.

Use AWS Config rules to detect and alert on violations
Why it's wrong here
Config rules detect violations after they occur but don't prevent the action. SCPs prevent the action proactively.
- ✗
Enable MFA delete on all accounts
Why it's wrong here
MFA delete applies specifically to S3 object deletion, not to disabling CloudTrail or Config.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse IAM policies with SCPs, thinking that IAM policies in each account can enforce organization-wide controls, but they fail to recognize that SCPs are the only mechanism that can prevent account administrators from disabling security services.
Detailed technical explanation
How to think about this question
SCPs are evaluated before IAM policies and can explicitly deny actions using the 'Deny' effect, which cannot be bypassed by any IAM policy within the account. For example, an SCP with 'Effect: Deny' and 'Action: [cloudtrail:StopLogging, config:StopConfigurationRecorder]' applied at the root OU ensures that even the root user of a member account cannot perform these actions. This leverages the AWS Organizations policy evaluation hierarchy, where SCPs act as a permission boundary that IAM policies cannot exceed.
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.
