CLF-C02 Billing, Pricing, and Support Practice Question
A company is evaluating a migration of its on-premises virtualized workloads to AWS. The CFO wants to understand the potential cost savings over a three-year period by shifting from capital expenditure (hardware purchases) to operational expenditure (pay-as-you-go). The team needs a tool that can provide a detailed comparison of the total cost of ownership (TCO) for the current on-premises environment versus running the same workloads on AWS, including hardware, software, labor, and facilities costs. Which AWS tool should the team use?
⚠ Common exam trap
Watch out — candidates often confuse the TCO Calculator with AWS Cost Explorer, assuming both provide cost comparisons, but Cost Explorer only shows historical AWS spend, not a forward-looking comparison with on-premises costs.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
AWS Total Cost of Ownership (TCO) Calculator
The AWS Total Cost of Ownership (TCO) Calculator is specifically designed to compare the costs of running workloads on-premises versus on AWS. It allows users to input details about their current on-premises infrastructure—including hardware, software, labor, and facilities—and generates a detailed side-by-side cost comparison over a specified period (e.g., three years). This directly addresses the CFO's need to understand potential savings from shifting from capital expenditure (CapEx) to operational expenditure (OpEx).
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 Budgets
Why it's wrong here
AWS Budgets is designed to help you monitor ongoing AWS spend by letting you set custom cost and usage thresholds and then triggering alerts when those thresholds are approached or exceeded. It works entirely within the AWS billing context and has no mechanism for modeling an on-premises environment's hardware, software, or operational expenses. Therefore, it is a reactive cost-monitoring tool, not a proactive TCO analysis tool for migration evaluation.
When this WOULD be correct
A company wants to set a monthly spending limit for its AWS services and receive notifications when costs approach or exceed that limit. AWS Budgets would be the correct tool to create and monitor these budgets.
- ✗
AWS Cost Explorer
Why it's wrong here
AWS Cost Explorer provides access to historical AWS cost and usage data through an interactive UI and API, with support for forecasting future AWS spend. Its purpose is to help you understand patterns in your existing AWS usage, such as identifying underutilized instances or predicting next month's bill. It does not accept data about on-premises infrastructure, nor does it offer any comparison between an on-premises datacenter and AWS, making it irrelevant for a TCO assessment.
When this WOULD be correct
A company wants to visualize and analyze its AWS spending patterns over time, identify cost drivers, and create custom cost and usage reports to optimize existing AWS costs.
- ✓
AWS Total Cost of Ownership (TCO) Calculator
Why this is correct
The AWS TCO Calculator is designed to compare the total cost of ownership of an existing on-premises environment with AWS, factoring in hardware, software, labor, facilities, and other costs. It produces a detailed report that helps organizations estimate the cost savings of migrating to AWS.
- ✗
AWS Trusted Advisor
Why it's wrong here
AWS Trusted Advisor is an operational tool that inspects your deployed AWS accounts against best practices and flags issues in categories like security, fault tolerance, and cost optimization. It only analyzes resources that already exist in AWS, not your on-premises infrastructure. Since it cannot ingest on-premises hardware, licensing, or operational costs, it is unable to produce the kind of before-and-after TCO comparison needed for migration planning.
When this WOULD be correct
A company wants to identify underutilized EC2 instances and receive recommendations to reduce costs by resizing or terminating them. AWS Trusted Advisor would be the correct tool to use for this specific cost optimization check.
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 BudgetsWrong answer — click to see why▾
Why this is wrong here
AWS Budgets is used to set custom cost and usage budgets and receive alerts when thresholds are exceeded, not to compare TCO between on-premises and AWS environments.
★ When this WOULD be the correct answer
A company wants to set a monthly spending limit for its AWS services and receive notifications when costs approach or exceed that limit. AWS Budgets would be the correct tool to create and monitor these budgets.
Why candidates choose this
Candidates may confuse cost management tools and think that any tool with 'cost' in its name can provide TCO comparisons, overlooking the specific purpose of each tool.
✗AWS Cost ExplorerWrong answer — click to see why▾
Why this is wrong here
AWS Cost Explorer analyzes historical cost data and forecasts future spending, but it does not compare on-premises TCO with AWS costs or include hardware, software, labor, and facilities costs.
★ When this WOULD be the correct answer
A company wants to visualize and analyze its AWS spending patterns over time, identify cost drivers, and create custom cost and usage reports to optimize existing AWS costs.
Why candidates choose this
Candidates may confuse cost analysis tools, thinking Cost Explorer can provide cost comparisons, but it only works with AWS usage data, not on-premises costs.
✗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 generate a detailed TCO comparison between on-premises and AWS environments, including hardware, software, labor, and facilities costs.
★ When this WOULD be the correct answer
A company wants to identify underutilized EC2 instances and receive recommendations to reduce costs by resizing or terminating them. AWS Trusted Advisor would be the correct tool to use for this specific cost optimization check.
Why candidates choose this
Candidates may confuse Trusted Advisor's cost optimization recommendations with a TCO analysis, assuming it can compare on-premises vs. AWS costs because it provides cost-saving suggestions.

Variation 1. A company is planning to migrate its on-premises infrastructure to AWS. The operations team wants to compare the total cost of ownership (TCO) between running workloads on-premises and running them on AWS. They need a tool that can accept details about their current on-premises servers (number of servers, CPU, memory, storage) and produce a detailed report comparing costs over a specified period, including savings from avoided hardware purchases, IT labor, and data center costs. Which AWS tool should the operations team use?
medium- A.AWS Cost Explorer
- ✓ B.AWS Total Cost of Ownership (TCO) Calculator
- C.AWS Pricing Calculator
- D.AWS Cost and Usage Report
Why B: The AWS Total Cost of Ownership (TCO) Calculator is specifically designed to compare the costs of running on-premises infrastructure versus AWS. It accepts detailed inputs about existing on-premises servers (such as CPU, memory, and storage) and generates a comprehensive report that includes savings from avoided hardware purchases, IT labor, and data center costs over a user-specified period. This directly matches the operations team's requirement for a detailed TCO comparison.
