CLF-C02 Billing, Pricing, and Support Practice Question
A company uses multiple AWS accounts and wants to enforce cost governance. The company needs to set a monthly cost budget of $10,000 for each account. When an account's actual or forecasted costs exceed this budget, the company wants to automatically apply a restrictive IAM policy that prevents the creation of new resources in that account. Additionally, the company wants to receive an email notification when the budget is exceeded. Which AWS feature should the company use to meet these requirements?
⚠ Common exam trap
Many candidates confuse AWS Cost Explorer's reporting capabilities with the automated enforcement and notification features that only AWS Budgets provides.
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 Budgets
AWS Budgets allows you to set custom cost and usage budgets, and when actual or forecasted costs exceed the budget threshold, it can trigger actions such as applying an IAM policy to restrict resource creation and sending SNS-based email notifications. This directly meets the requirement for automated enforcement and alerting per account.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
AWS Cost Explorer
Why it's wrong here
AWS Cost Explorer is a read-only analytics and visualization tool that lets you query historical cost and usage data, group by dimensions like account, service, or tag, and view forecasts. However, it has no capability to define hard spending limits, evaluate a policy condition, or initiate any automated remediation. It simply presents data for humans to interpret, so it cannot enforce the restrictive IAM policy required by the scenario.
- ✓
AWS Budgets
Why this is correct
AWS Budgets enables you to set custom budgets for costs or usage and configure budget actions that automatically enforce policies or send notifications when the budget is exceeded. This directly meets the requirement for automated application of a restrictive IAM policy and email alerts.
- ✗
AWS Cost Anomaly Detection
Why it's wrong here
AWS Cost Anomaly Detection uses machine learning models to establish a baseline of normal spending and alerts you to unusual spikes or patterns, with root-cause analysis for the affected services and accounts. It is designed to detect deviations from behavior, not to enforce a strict budget ceiling, and while it can notify via SNS it cannot attach or remove IAM policies. Fixed budget enforcement is outside its purpose.
When this WOULD be correct
A company wants to detect and alert on anomalous cost spikes (e.g., 20% above normal) across AWS accounts, without setting fixed budgets or automating policy changes. AWS Cost Anomaly Detection would be the correct service.
- ✗
AWS Trusted Advisor
Why it's wrong here
AWS Trusted Advisor runs a set of automated checks against your account to identify underutilized resources, service quotas, and security gaps, then provides cost optimization recommendations. These checks are advisory; Trusted Advisor can flag issues but has no mechanism to set a budget threshold or automatically apply a restrictive IAM policy when spending surpasses a limit. You would have to implement any recommended savings manually.
When this WOULD be correct
A company wants to receive a list of cost optimization recommendations for underutilized EC2 instances and idle RDS databases to reduce monthly spending. AWS Trusted Advisor would be the correct choice for providing these specific cost optimization checks.
Option-by-option analysis
Why each answer is right or wrong
Understanding why wrong answers are wrong — and when they would be correct — is what separates a 750 score from a 900. The CLF-C02 exam frequently reuses these exact scenarios with slightly different constraints.
✓AWS BudgetsCorrect answer▾
Why this is correct
AWS Budgets enables you to set custom budgets for costs or usage and configure budget actions that automatically enforce policies or send notifications when the budget is exceeded. This directly meets the requirement for automated application of a restrictive IAM policy and email alerts.
✗AWS Cost Anomaly DetectionWrong answer — click to see why▾
Why this is wrong here
AWS Cost Anomaly Detection identifies unusual spending patterns but does not support automated budget enforcement or restrictive IAM policy application based on budget thresholds.
★ When this WOULD be the correct answer
A company wants to detect and alert on anomalous cost spikes (e.g., 20% above normal) across AWS accounts, without setting fixed budgets or automating policy changes. AWS Cost Anomaly Detection would be the correct service.
Why candidates choose this
Candidates may confuse anomaly detection with budget enforcement, assuming 'anomaly' includes exceeding a budget, and overlook that AWS Budgets is the service designed for threshold-based alerts and automated actions.
✗AWS Trusted AdvisorWrong answer — click to see why▾
Why this is wrong here
AWS Trusted Advisor provides recommendations for cost optimization, security, and performance, but it does not support setting budgets, triggering automated IAM policy actions, or sending email notifications when costs exceed thresholds.
★ When this WOULD be the correct answer
A company wants to receive a list of cost optimization recommendations for underutilized EC2 instances and idle RDS databases to reduce monthly spending. AWS Trusted Advisor would be the correct choice for providing these specific cost optimization checks.
Why candidates choose this
Candidates may confuse Trusted Advisor's cost optimization recommendations with the ability to enforce budgets, or they might think its 'cost' category includes budget alerts and automated actions.
