Full question →mediummultiple choiceObjective-mapped
A company is planning to migrate a legacy application to AWS and wants to estimate the monthly cost of running the new workload. The company needs to compare costs across different Amazon EC2 instance types, regions, and pricing models (On-Demand, Reserved, and Spot). The team also wants to include estimated costs for related services such as Amazon EBS storage and data transfer. Which AWS tool should the company use to generate this cost estimate?
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
Best answer
AWS Pricing Calculator
Correct. The AWS Pricing Calculator is designed to produce cost estimates for new AWS workloads. You can select specific EC2 instance types, pricing models, regions, and associated services like EBS and data transfer to get a monthly estimate.
B
Distractor review
AWS Cost Explorer
Incorrect. AWS Cost Explorer provides visualizations and analysis of historical AWS costs and usage. It does not generate cost estimates for workloads that have not yet been deployed.
C
Distractor review
AWS Budgets
Incorrect. AWS Budgets allows you to set custom budgets and receive alerts when costs or usage exceed (or are forecasted to exceed) your budgeted amount. It does not create upfront cost estimates for new services.
D
Distractor review
AWS Trusted Advisor
Incorrect. AWS Trusted Advisor inspects your AWS environment and offers recommendations to help you follow best practices, such as optimizing costs on underutilized resources. It does not provide cost estimation for new workloads before deployment.
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 Pricing Calculator — The AWS Pricing Calculator is the correct tool for creating a custom cost estimate for a new workload before it is deployed. It allows users to select services, configure details (e.g., instance type, pricing model, region), and view a detailed monthly cost breakdown. This is ideal for planning and budgeting for a future migration. AWS Cost Explorer is used for analyzing historical costs and usage, not for estimating new workloads. AWS Budgets is used to set cost thresholds and receive alerts. AWS Trusted Advisor provides best-practice recommendations for cost optimization, security, and performance, but it does not generate cost estimates for new configurations.
