A company operates 40 AWS accounts and wants chargeback by application, environment, and business unit. Finance needs detailed line items, and engineering wants consistent monthly reports without manual spreadsheet work. The current tagging scheme is inconsistent, and many resources are missing billing metadata. Which three actions should the architect recommend? Select three.

Use AWS Budgets alone because it provides the most detailed line-item attribution.

Budgets is primarily for alerts and threshold tracking; it is not the detailed reporting engine needed for chargeback.

Rely only on the Cost Explorer console for chargeback accuracy.

Cost Explorer is useful for visualization and analysis, but it is not enough by itself for a robust multi-account chargeback process.

What does this SAA-C03 question test?

Read the scenario before looking for a memorised answer.

What is the correct answer to this question?

The correct answer is: Standardize cost allocation tags such as Application, Environment, and BusinessUnit. — Accurate chargeback starts with consistent resource tagging, then requires those tags to be activated so AWS can use them in billing reports. The Cost and Usage Report provides the granular line-item data that finance needs and that engineering can query repeatedly without manual work. Together, these steps create a durable reporting pipeline for a multi-account organization. Why others are wrong: AWS Budgets is best for alerts and budget thresholds, not fine-grained attribution. Cost Explorer is helpful for visibility, but it does not replace a governed tagging strategy plus a detailed report source such as CUR.

What should I do if I get this SAA-C03 question wrong?

Then try more questions from the same exam bank and focus on understanding why the wrong options are tempting.
