AWS Certified Cloud Practitioner — Question 664

A company is running workloads for multiple departments within a single VPC. The company needs to be able to bill each department for its resource usage.

Which action should the company take to accomplish this goal with the LEAST operational overhead?

Answer options

• A. Add a department tag to each resource and configure cost allocation tags.
• B. Move each department resource to its own VPC.
• C. Move each department resource to its own AWS account.
• D. Use AWS Organizations to get a billing report for each department.

Correct answer: A

Explanation

Applying cost allocation tags is the most efficient method because it requires no architectural changes to the existing single VPC infrastructure. Migrating resources to separate VPCs or AWS accounts introduces unnecessary migration and management overhead. AWS Organizations cannot generate separate departmental billing reports unless the resources are already separated into different accounts or properly tagged.
