AWS Certified Solutions Architect – Professional (SAP-C02) — Question 388

A company has an organization in AWS Organizations that includes a separate AWS account for each of the company’s departments. Application teams from different departments develop and deploy solutions independently.

The company wants to reduce compute costs and manage costs appropriately across departments. The company also wants to improve visibility into billing for individual departments. The company does not want to lose operational flexibility when the company selects compute resources.

Which solution will meet these requirements?

Answer options

• A. Use AWS Budgets for each department. Use Tag Editor to apply tags to appropriate resources. Purchase EC2 Instance Savings Plans.
• B. Configure AWS Organizations to use consolidated billing. Implement a tagging strategy that identifies departments. Use SCPs to apply tags to appropriate resources. Purchase EC2 Instance Savings Plans.
• C. Configure AWS Organizations to use consolidated billing. Implement a tagging strategy that identifies departments. Use Tag Editor to apply tags to appropriate resources. Purchase Compute Savings Plans.
• D. Use AWS Budgets for each department. Use SCPs to apply tags to appropriate resources. Purchase Compute Savings Plans.

Correct answer: C

Explanation

Compute Savings Plans provide the greatest operational flexibility as they apply to EC2 instances, AWS Fargate, and AWS Lambda regardless of instance family, size, or region, unlike EC2 Instance Savings Plans which restrict choices. Consolidated billing combined with tagging resources using Tag Editor allows the company to track and allocate costs accurately across departments. SCPs cannot be used to directly apply tags to existing resources, making Tag Editor the appropriate choice for implementing the tagging strategy.
