- A
AWS Trusted Advisor
Why wrong: AWS Trusted Advisor inspects your AWS environment and makes recommendations for saving money, improving system performance, and closing security gaps. However, it does not provide the deep historical cost analysis, forecasting, or Reserved Instance purchase recommendations that Cost Explorer offers. It can give cost optimization checks (e.g., idle instances) but not the granular cost trends and forecasting.
- B
AWS Budgets
Why wrong: AWS Budgets allows you to set custom budgets to track your cost and usage and alerts you when you exceed (or are forecasted to exceed) your budget. It does not provide the comprehensive historical analysis, cost trends, or Reserved Instance recommendations that are needed.
- C
AWS Cost Explorer
AWS Cost Explorer has a default dashboard that gives you a view of your cost and usage over time. It enables you to filter by service, linked account, or tags, and provides forecasting up to 12 months ahead. Cost Explorer also provides Reserved Instance purchase recommendations based on your actual usage patterns, helping you maximize savings. This matches the finance team's requirements exactly.
- D
AWS Pricing Calculator
Why wrong: AWS Pricing Calculator (formerly Simple Monthly Calculator) is used to estimate the cost of running a new workload or architecture. It is forward-looking and does not analyze existing historical usage or provide Reserved Instance recommendations based on past data.
Master AWS Cost Explorer: Historical Analysis, Forecasting, and RI Recommendations
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. 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 has been running multiple workloads on AWS for over six months. The finance team needs to gain visibility into historical cost and usage data, identify which services are driving the most spend, forecast future monthly costs, and receive recommendations for purchasing Reserved Instances to achieve the highest savings. The team wants to use a native AWS tool that provides this functionality without requiring any third-party software. Which AWS tool should the finance team use?

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse AWS Budgets with Cost Explorer because both deal with cost management, but Budgets is for setting limits and alerts, not for in-depth historical analysis, forecasting, or RI recommendations.
Detailed technical explanation
How to think about this question
AWS Cost Explorer uses a pre-built dashboard with customizable filters (e.g., by service, linked account, or tag) and supports granular time ranges down to hourly data for the last 14 days. Its forecasting engine applies machine learning algorithms to historical usage to predict future costs, and RI recommendations are calculated by analyzing your On-Demand usage over the past 7, 30, or 60 days to suggest optimal instance types, tenancy, and payment options (No Upfront, Partial Upfront, All Upfront) for maximum savings.
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 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.
