Question 1mediummultiple choice
Full question →mediummultiple choiceObjective-mapped
A company wants to review its AWS spending for the past six months to identify which services and business units are driving costs. The finance team needs to interactively examine cost trends, filter by service and account, and visualize the data without setting up complex reports. Which AWS service or tool should the company use to meet these requirements?
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 Cost Explorer
AWS Cost Explorer offers a ready-to-use graphical interface to explore and analyze your AWS costs and usage over custom time periods, with filters by service, account, region, and tags. It directly meets the need for interactive trend analysis without requiring additional setup.
B
Distractor review
AWS Budgets
AWS Budgets is used to set spending thresholds and receive alerts when costs exceed those limits. It does not provide historical trend analysis or interactive cost visualization for past months.
C
Distractor review
AWS Trusted Advisor
AWS Trusted Advisor inspects your environment and makes recommendations for cost optimization, performance, security, and fault tolerance. While it can identify cost-saving opportunities, it does not provide a historical spending analysis or interactive dashboards.
D
Distractor review
AWS Cost and Usage Reports
AWS Cost and Usage Reports deliver the most detailed billing data as CSV files, but they require additional tools (e.g., Amazon Athena, Amazon QuickSight) for querying and visualization. They are not designed for immediate interactive exploration.
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 Cost Explorer — AWS Cost Explorer is the correct choice because it provides a pre-built, interactive dashboard for visualizing, understanding, and managing AWS costs and usage over time. Users can filter by service, linked account, tags, and other dimensions, and view trends without additional setup. AWS Budgets is used for proactive alerts, not historical analysis. AWS Trusted Advisor offers cost optimization checks but lacks the detailed historical trend analysis and interactive visualization. AWS Cost and Usage Reports provides raw data for deep analysis but requires loading into a tool like Amazon Athena or QuickSight, making it less suitable for quick interactive exploration.
