- A
AWS Consolidated Billing
Why wrong: 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
AWS Cost Explorer with tag filtering
Why wrong: 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
AWS Budgets with tag-based alerts
Why wrong: 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
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.
Quick Answer
The answer is AWS Cost and Usage Reports with cost allocation tags activated. This is the correct choice because the Cost and Usage Report (CUR) provides the most granular billing data available, including all user-defined cost allocation tags like the 'Project' tag, and can be delivered to an S3 bucket for detailed analysis across all accounts in an AWS Organization. On the AWS Certified Cloud Practitioner CLF-C02 exam, this scenario tests your understanding of which billing tool offers the deepest level of detail for grouping costs by custom tags, often contrasting CUR with simpler tools like AWS Cost Explorer or budgets. A common trap is choosing Cost Explorer, which can filter by tags but lacks the raw, downloadable detail needed for a comprehensive combined report. Remember the memory tip: "CUR is the full story; Cost Explorer is just the summary."
CLF-C02 Billing, Pricing, and Support Practice Question
This CLF-C02 practice question tests your understanding of billing, pricing, and support. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
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?

Correct answer & explanation
AWS Cost and Usage Reports with cost allocation tags activated
AWS Cost and Usage Reports (CUR) with cost allocation tags activated is the correct choice because it provides the most detailed billing data, including all tags, and can be delivered to an S3 bucket for analysis. This allows the finance team to group costs by the 'Project' tag across all accounts in the AWS Organization, meeting the requirement for a detailed, combined report.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse the ability to filter or visualize costs in Cost Explorer with the need for a detailed, exportable report that groups costs by tags across all accounts, which only CUR provides.
Detailed technical explanation
How to think about this question
AWS Cost and Usage Reports (CUR) contain the most granular data, including line items for each resource usage, and can include cost allocation tags (both user-defined and AWS-generated). The report is delivered to an S3 bucket in CSV or Parquet format, enabling integration with tools like Amazon Athena or QuickSight for custom queries and grouping. A key subtlety is that cost allocation tags must be activated in the Billing and Cost Management console before they appear in the CUR; otherwise, the tag data will be missing from the report.
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.
TExam Day Tips
- 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.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.

Same concept, more angles
2 more ways this is tested on CLF-C02
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. A company runs separate AWS accounts for development, testing, and production workloads. The finance team wants a single view that shows the total spending across all accounts. Additionally, the team wants to benefit from volume discount pricing by aggregating usage across all accounts. The team also needs to allocate costs to individual projects based on custom tags applied to resources. Which AWS feature should the finance team use to meet all these requirements?
medium- A.AWS Cost Explorer
- ✓ B.AWS Organizations consolidated billing
- C.AWS Budgets
- D.AWS Trusted Advisor
Why B: AWS Organizations consolidated billing allows you to aggregate usage across all linked accounts, enabling volume discount pricing (e.g., lower S3 storage rates or EC2 Reserved Instance tiers) based on combined usage. It also provides a single payer account that can view total spending across all accounts, and supports cost allocation using custom tags (e.g., Project or CostCenter) via AWS Cost Explorer or AWS Cost and Usage Reports. This directly meets the finance team's requirements for unified spending visibility, volume discounts, and tag-based cost allocation.
Variation 2. A company uses AWS Organizations to manage multiple accounts. The finance team needs to perform a detailed cost analysis by joining AWS usage data with their internal accounting system. They require hourly-level billing data that includes resource IDs, operation types, and cost allocation tags. The data must be available in a CSV file that can be imported into their financial software. Which AWS tool or service should the finance team use to meet this requirement?
medium- A.AWS Cost Explorer
- B.AWS Budgets
- ✓ C.AWS Cost and Usage Report
- D.AWS Trusted Advisor
Why C: The AWS Cost and Usage Report (CUR) is the correct choice because it provides the most granular billing data available, including hourly-level usage, resource IDs, operation types, and cost allocation tags. The report can be delivered to an Amazon S3 bucket in CSV format, making it directly importable into the finance team's financial software for detailed cost analysis.
