Question 1mediummultiple choice
Full question →mediummultiple choiceObjective-mapped
A company manages multiple AWS accounts under a single AWS Organizations structure with consolidated billing. The finance team needs to analyze historical cost and usage data across all accounts for the past six months. They want to filter the data by service (e.g., Amazon EC2, Amazon S3), AWS Region, and individual account. Additionally, they want to generate a line chart showing monthly trends and a forecast of future costs based on historical usage patterns. Which AWS tool should the finance team use to meet all of 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
Distractor review
AWS Budgets
AWS Budgets allows you to set custom budgets and receive alerts when costs or usage exceed (or are forecasted to exceed) your budgeted amount. However, it does not provide the comprehensive historical analysis, filtering, and trend visualization capabilities needed for exploring six months of data across multiple dimensions.
B
Distractor review
AWS Trusted Advisor
AWS Trusted Advisor inspects your AWS environment and makes recommendations for cost optimization, performance, security, fault tolerance, and service limits. While it can identify idle resources or underutilized instances, it does not offer the detailed, filterable historical cost and usage analysis or forecasting features that the finance team requires.
C
Best answer
AWS Cost Explorer
AWS Cost Explorer is the correct tool. It provides a pre-built dashboard and reports that allow you to visualize and analyze your AWS costs and usage. You can filter by service, Region, account, and other dimensions, view trends over time, and generate forecasts. It meets all the requirements described in the scenario.
D
Distractor review
AWS Pricing Calculator
AWS Pricing Calculator is used to estimate the cost of AWS services based on expected usage before you deploy resources. It is a planning tool for prospective costs, not a tool for analyzing historical cost and usage data that has already been incurred.
Common exam trap
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Technical deep dive
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
- Static NAT maps one inside address to one outside address.
- PAT allows many inside hosts to share one public address using ports.
- Inside local and inside global describe the private and translated addresses.
- NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
- Identify inside and outside interfaces first.
- Check whether the scenario needs static NAT, dynamic NAT or PAT.
- Do not confuse NAT matching ACLs with normal packet-filtering intent.

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?
Static NAT maps one inside address to one outside address.
What is the correct answer to this question?
The correct answer is: AWS Cost Explorer — AWS Cost Explorer is the native AWS tool designed for visualizing, understanding, and managing AWS costs and usage over time. It allows users to explore historical data with filters (by service, region, account, etc.), view trends in graph or table format, and create forecasts for up to 12 months ahead. AWS Budgets focuses on setting spending limits and sending alerts, but does not offer the same depth of historical analysis or forecasting visualization. AWS Trusted Advisor provides cost optimization recommendations based on checks, not detailed cost and usage exploration. AWS Pricing Calculator is used to estimate costs for planned usage, not to analyze historical data. Therefore, AWS Cost Explorer is the correct tool for this scenario.
