Question 1mediummultiple choice
Full question →mediummultiple choiceObjective-mapped
A company uses multiple AWS accounts and needs to perform granular cost and usage analysis using standard SQL queries. The cloud operations team requires the most detailed data possible, including resource-level attributes such as instance type, usage quantity, and cost allocation tags. This data must be automatically delivered to an Amazon S3 bucket on a daily basis for long-term retention and querying. Which AWS service should the company use to generate this dataset?
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 Cost Explorer
Cost Explorer provides interactive charts and basic CSV exports of cost data, but it does not automatically deliver the most granular, resource-level data to S3 in a format optimized for SQL querying. It is designed for visualization and lightweight analysis, not for building custom analytics pipelines.
B
Distractor review
AWS Budgets
AWS Budgets is used to set spending or usage thresholds and receive alerts. While budgets can include cost filters, they do not generate the detailed line-item reports needed for SQL-based cost analysis. This service is for monitoring and notification, not for data export.
C
Best answer
AWS Cost and Usage Report
The AWS Cost and Usage Report (CUR) contains the most detailed billing and usage data, including individual resource IDs, tags, and hourly usage. It is delivered to an Amazon S3 bucket in a structured format (CSV or Parquet) and can be queried with Amazon Athena, making it the correct choice for granular SQL-based cost analysis.
D
Distractor review
AWS Pricing Calculator
The AWS Pricing Calculator is a tool for estimating future costs based on user-specified configurations. It does not provide historical cost or usage data, and it cannot generate ongoing reports delivered to S3. It is not suited for analyzing existing usage patterns.
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 and Usage Report — The AWS Cost and Usage Report (CUR) is the most comprehensive source of cost and usage data available. It contains line-item details for each AWS resource, including tags, and is delivered to an Amazon S3 bucket. The reports can be queried with Amazon Athena, Amazon Redshift, or other SQL-based tools. AWS Cost Explorer provides a graphical interface and basic data export but does not offer the same level of granularity or native S3 delivery for SQL querying. AWS Budgets is for setting spending limits and alerts, not for raw data export. AWS Pricing Calculator is used to estimate future costs, not to access historical usage data.
