AWS Certified Cloud Practitioner (CLF-C02) — Question 372

A company wants to launch multiple workloads on AWS. Each workload is related to a different business unit. The company wants to separate and track costs for each business unit.

Which solution will meet these requirements with the LEAST operational overhead?

Answer options

• A. Use AWS Organizations and create one account for each business unit.
• B. Use a spreadsheet to control the owners and cost of each resource.
• C. Use an Amazon DynamoDB table to record costs for each business unit.
• D. Use the AWS Billing console to assign owners to resources and track costs.

Correct answer: A

Explanation

Using AWS Organizations to set up dedicated accounts for each business unit simplifies cost allocation and tracking because AWS naturally aggregates and separates billing data at the account level. Alternative approaches like manual spreadsheets or custom Amazon DynamoDB tables require significant manual effort and custom development, increasing operational overhead. The AWS Billing console itself cannot directly assign owners to resources without a robust tagging strategy or a multi-account architecture.
