- A
AWS Budgets
Why wrong: AWS Budgets allows you to set custom budgets and receive alerts when costs or usage exceed (or are forecasted to exceed) your budgeted amount. However, it does not provide the comprehensive historical analysis, filtering, and trend visualization capabilities needed for exploring six months of data across multiple dimensions.
- B
AWS Trusted Advisor
Why wrong: AWS Trusted Advisor inspects your AWS environment and makes recommendations for cost optimization, performance, security, fault tolerance, and service limits. While it can identify idle resources or underutilized instances, it does not offer the detailed, filterable historical cost and usage analysis or forecasting features that the finance team requires.
- C
AWS Cost Explorer
AWS Cost Explorer is the correct tool. It provides a pre-built dashboard and reports that allow you to visualize and analyze your AWS costs and usage. You can filter by service, Region, account, and other dimensions, view trends over time, and generate forecasts. It meets all the requirements described in the scenario.
- D
AWS Pricing Calculator
Why wrong: AWS Pricing Calculator is used to estimate the cost of AWS services based on expected usage before you deploy resources. It is a planning tool for prospective costs, not a tool for analyzing historical cost and usage data that has already been incurred.
CLF-C02 Billing, Pricing, and Support Practice Question
This CLF-C02 practice question tests your understanding of billing, pricing, and support. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. A key principle to apply: aWS Cost Explorer visualizes historical cost and usage data.. 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 manages multiple AWS accounts under a single AWS Organizations structure with consolidated billing. The finance team needs to analyze historical cost and usage data across all accounts for the past six months. They want to filter the data by service (e.g., Amazon EC2, Amazon S3), AWS Region, and individual account. Additionally, they want to generate a line chart showing monthly trends and a forecast of future costs based on historical usage patterns. Which AWS tool should the finance team use to meet all of these requirements?
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 Cost Explorer
AWS Cost Explorer is the correct tool because it provides a pre-built dashboard with historical cost and usage data for up to the last 12 months, supports filtering by service (e.g., Amazon EC2, Amazon S3), AWS Region, and linked account (individual account), and can generate line charts showing monthly trends. It also includes a forecasting feature that uses machine learning to predict future costs based on historical usage patterns, meeting all the finance team's requirements.
Key principle: AWS Cost Explorer visualizes historical cost and usage data.

- ✗
AWS Budgets
Why it's wrong here
AWS Budgets allows you to set custom budgets and receive alerts when costs or usage exceed (or are forecasted to exceed) your budgeted amount. However, it does not provide the comprehensive historical analysis, filtering, and trend visualization capabilities needed for exploring six months of data across multiple dimensions.
When this WOULD be correct
A finance team needs to set a monthly budget for EC2 usage and receive alerts when costs exceed 80% of the budget. AWS Budgets would be the correct tool to create cost budgets and configure threshold-based notifications.
- ✗
AWS Trusted Advisor
Why it's wrong here
AWS Trusted Advisor inspects your AWS environment and makes recommendations for cost optimization, performance, security, fault tolerance, and service limits. While it can identify idle resources or underutilized instances, it does not offer the detailed, filterable historical cost and usage analysis or forecasting features that the finance team requires.
When this WOULD be correct
A company wants to check if their AWS account is following best practices for cost optimization, such as identifying idle resources or underutilized Amazon EBS volumes, and receive recommendations to reduce costs.
- ✓
AWS Cost Explorer
Why this is correct
AWS Cost Explorer is the correct tool. It provides a pre-built dashboard and reports that allow you to visualize and analyze your AWS costs and usage. You can filter by service, Region, account, and other dimensions, view trends over time, and generate forecasts. It meets all the requirements described in the scenario.

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.

Why this is correct
AWS Cost Explorer is the correct tool. It provides a pre-built dashboard and reports that allow you to visualize and analyze your AWS costs and usage. You can filter by service, Region, account, and other dimensions, view trends over time, and generate forecasts. It meets all the requirements described in the scenario.
✗AWS BudgetsWrong answer — click to see why▾
Why this is wrong here
AWS Budgets is designed for setting cost and usage alerts, not for analyzing historical data, generating line charts, or producing forecasts. It cannot provide the detailed filtering and visualization required.
★ When this WOULD be the correct answer
A finance team needs to set a monthly budget for EC2 usage and receive alerts when costs exceed 80% of the budget. AWS Budgets would be the correct tool to create cost budgets and configure threshold-based notifications.
Why candidates choose this
Candidates may confuse AWS Budgets with cost analysis tools because both involve cost management, but Budgets focuses on proactive alerts rather than retrospective analysis and forecasting.
✗AWS Trusted AdvisorWrong answer — click to see why▾
Why this is wrong here
AWS Trusted Advisor provides recommendations for cost optimization, performance, security, and fault tolerance, but it does not offer historical cost and usage analysis, filtering by service/region/account, or forecasting capabilities.
★ When this WOULD be the correct answer
A company wants to check if their AWS account is following best practices for cost optimization, such as identifying idle resources or underutilized Amazon EBS volumes, and receive recommendations to reduce costs.
Why candidates choose this
Candidates may confuse Trusted Advisor's cost optimization checks with cost analysis tools, thinking it can provide historical data and forecasts because it offers cost-related recommendations.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may confuse AWS Budgets with cost analysis tools, but AWS Budgets only monitors against set limits and does not provide historical trend analysis or forecasting, which are essential for the finance team's requirements.
Detailed technical explanation
How to think about this question
AWS Cost Explorer uses the AWS Cost and Usage Reports (CUR) as its data source, which provides granular, hourly cost and usage data. The forecasting feature leverages Amazon Forecast, a fully managed service that uses machine learning algorithms to generate time-series predictions, allowing users to view projected costs up to 12 months ahead. A real-world scenario is a multi-account organization using Cost Explorer to identify which account and region are driving EC2 costs, then using the forecast to plan budget adjustments.
KKey Concepts to Remember
- AWS Cost Explorer visualizes historical cost and usage data.
- It supports filtering by service, Region, account, and more.
- Cost Explorer generates charts for trends and provides cost forecasts.
- It works across multiple accounts in AWS Organizations for consolidated billing.
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
AWS Cost Explorer visualizes historical cost and usage data.
Real-world example
How this comes up in practice
A startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.
