Full question →mediummultiple choiceObjective-mapped
A company is planning to migrate its on-premises data center to AWS. The finance team needs to compare the current on-premises infrastructure costs (including servers, storage, networking, and personnel) against the projected costs of running identical workloads on AWS over a three-year period. The team wants to input detailed specifications of their existing hardware and get a comprehensive report that highlights potential savings and provides a total cost of ownership (TCO) comparison. Which AWS tool should the finance team use?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Distractor review
AWS Pricing Calculator
The AWS Pricing Calculator is used to estimate the monthly cost of AWS services for new deployments. It does not accept on-premises specifications as input and does not generate a TCO comparison against existing infrastructure.
B
Distractor review
AWS Cost Explorer
AWS Cost Explorer provides visualizations and analysis of historical AWS usage and costs. It does not accept on-premises infrastructure details and cannot compare costs between on-premises and AWS.
C
Best answer
AWS Total Cost of Ownership (TCO) Calculator
The AWS TCO Calculator is specifically designed to help organizations compare the costs of running their current on-premises workloads against AWS. It accepts detailed on-premises specifications and produces a comparative TCO report, including potential savings over multiple years.
D
Distractor review
AWS Simple Monthly Calculator
The AWS Simple Monthly Calculator was an earlier tool for estimating AWS service costs but has been replaced by the AWS Pricing Calculator. It is not designed to accept on-premises inputs or perform TCO comparisons.
Common exam trap
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Technical deep dive
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- 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.

Question 1
A developer needs to launch a test server for a new application prototype. The developer logs into the AWS Management Console, selects an Amazon EC2 instance type, configures the security group, and starts the instance. The instance is running within two minutes, and the developer did not need to submit a formal request to the company's IT procurement team or wait for approval from a cloud administrator. Which essential characteristic of cloud computing does this scenario best demonstrate?
Question 2
A solutions architect is planning a new web application on AWS. The workload will include 3 Amazon EC2 instances (t3.medium) running 24/7, an Application Load Balancer, and an Amazon RDS for MySQL db.t3.small database. The architect needs to estimate the monthly cost for the first year, considering different purchasing options (On-Demand, 1-year All Upfront Reserved Instance, and Compute Savings Plan). Which AWS tool should the architect use to create this estimate?
Question 3
A company's development team frequently needs temporary test environments. A developer can log into the AWS Management Console, select an Amazon EC2 instance type, configure storage, and launch the instance within minutes without any interaction with the IT infrastructure team. This capability is an example of which essential characteristic of cloud computing?
Question 4
A company's finance team needs to analyze AWS spending in detail. They require a report that includes hourly cost data for each AWS service, each individual resource (e.g., a specific EC2 instance), and any cost allocation tags applied. The team plans to export this data to an Amazon S3 bucket and then import it into a custom business intelligence (BI) analytics dashboard. Which AWS tool should the finance team use to generate this level of detailed cost data?
Question 5
A company uses AWS for its development environment. The finance team wants to set a monthly budget of $10,000. They want to receive an email notification when the actual costs reach 80% of the budget ($8,000) and again when costs exceed the budget. The team needs a managed AWS service that can automatically send these alerts without requiring custom code or third-party tools. Which AWS service should the team use?
Question 6
A company uses AWS Organizations to manage multiple accounts. The security team needs to enforce a policy that restricts SSH access (port 22) from the internet (0.0.0.0/0) in all VPCs across all accounts. The team wants to centrally define the allowed rules and automatically apply them to newly created VPCs and security groups, while also automatically remediating any existing non-compliant security groups. Which AWS service should the team use?
FAQ
Questions learners often ask
What does this CLF-C02 question test?
Read the scenario before looking for a memorised answer.
What is the correct answer to this question?
The correct answer is: AWS Total Cost of Ownership (TCO) Calculator — The AWS Total Cost of Ownership (TCO) Calculator is the correct tool for comparing the costs of on-premises infrastructure with AWS. It allows users to input details about their existing on-premises environment, such as server configurations, storage types, and network usage, and then generates a detailed report that estimates the AWS costs and potential savings. The other tools serve different purposes. The AWS Pricing Calculator is used to estimate costs for new AWS deployments, not to compare against on-premises. The AWS Cost Explorer analyzes historical AWS usage and costs. The AWS Simple Monthly Calculator is an older tool replaced by the AWS Pricing Calculator.
