#61. A company wants to migrate its on-premises workloads to the AWS Cloud. The company wants to separate workloads for chargeback to different departments.
Which AWS services or features will meet these requirements? (Choose two.)

 

• A. Placement groups
• B. Consolidated billing
• C. Edge locations
• D. AWS Config
• E. Multiple AWS accounts

 

Selected Answer: BE

B. Consolidated Billing

Consolidated billing is a feature of AWS Organizations that allows you to combine billing for multiple AWS accounts. With consolidated billing, each department can have its own AWS account for tracking and managing its resources separately, while the company enjoys the convenience of a single payment method for all these accounts. This setup makes it easier to track costs and implement chargeback mechanisms.
E. Multiple AWS Accounts

E. Multiple AWS accounts

Creating multiple AWS accounts, one for each department, is an effective way to segregate resources, manage permissions, and track costs separately. This approach enhances security by limiting the scope of access and impact of changes, and it simplifies the process of attributing costs to the right department. Combined with consolidated billing, it provides both organizational flexibility and centralized financial control.
