Question 1mediummultiple choice
Full question →mediummultiple choiceObjective-mapped
A company uses AWS Organizations with separate accounts for development, testing, and production. The finance team wants to track monthly spending by internal project, but a single project may use resources across multiple accounts. The team has applied a 'Project' tag to all resources. They need a detailed billing report that shows costs grouped by this Project tag, combining data from all accounts. Which AWS feature should they enable to meet this requirement?
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 Consolidated Billing
Consolidated Billing combines the costs of multiple accounts into a single bill, but it does not provide a report that groups costs by custom tags across accounts. It is a prerequisite for some features but not the direct solution for this requirement.
B
Distractor review
AWS Cost Explorer with tag filtering
Cost Explorer is an interactive tool for visualizing and analyzing cost data. While it can filter costs by tags, it does not automatically produce a scheduled, detailed billing report aggregated by tags across all accounts. It is more suitable for ad-hoc analysis than for generating a periodic report.
C
Distractor review
AWS Budgets with tag-based alerts
AWS Budgets allows you to set cost or usage thresholds and receive alerts when costs exceed those thresholds. It can filter by tags, but it is not designed to generate a comprehensive billing report grouped by tags. Its purpose is proactive monitoring, not historical reporting.
D
Best answer
AWS Cost and Usage Reports with cost allocation tags activated
The AWS Cost and Usage Reports (CUR) provides the most detailed billing data available. When cost allocation tags are activated and the CUR is configured to include those tags, the resulting CSV report contains line items tagged with the 'Project' values. This report can be generated regularly and includes data from all accounts in the organization, allowing the finance team to group and analyze costs by project across all accounts.
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 Reports with cost allocation tags activated — The correct solution is to activate the AWS Cost and Usage Reports along with cost allocation tags. This combination produces a detailed CSV file that includes line items and allows grouping by tags (e.g., Project) across all linked accounts in an AWS Organization. Consolidated Billing (Option A) simply aggregates costs but does not provide tag-based grouping. Cost Explorer (Option B) is a visualization tool that can filter by tags but is not a detailed report export. AWS Budgets (Option C) is for setting cost thresholds and alerts, not generating detailed billing reports. Therefore, Option D is the correct answer.
