AWS Certified SysOps Administrator – Associate (legacy) — Question 280

An organization is planning to use AWS for 5 different departments. The finance department is responsible to pay for all the accounts. However, they want the cost separation for each account to map with the right cost center. How can the finance department achieve this?

Answer options

• A. Create 5 separate accounts and make them a part of one consolidate billing
• B. Create 5 separate accounts and use the IAM cross account access with the roles for better management
• C. Create 5 separate IAM users and set a different policy for their access
• D. Create 5 separate IAM groups and add users as per the department's employees

Correct answer: A

Explanation

Consolidated billing in AWS allows an organization to consolidate payment for multiple AWS accounts under a single paying account while still receiving detailed cost breakdowns for each linked account. This enables the finance department to easily map costs to specific department cost centers. The other options focus on access control and identity management rather than billing and cost allocation.
