AWS Certified SysOps Administrator – Associate (legacy) — Question 120

Company A purchases Company B and inherits three new AWS accounts. Company A would like to centralize billing and Reserved Instance benefits but wants to keep all other resources separate.
How can this be accomplished?

Answer options

• A. Implement AWS Organizations and create a service control policy that defines the billing relationship with the new master account.
• B. Configure AWS Organizations Consolidated Billing and provide the finance team with IAM access to the billing console.
• C. Send Cost and Usage Reports files to a central Amazon S3 bucket, and load the data into Amazon Redshift. Use Amazon QuickSight to provide visualizations to the finance team.
• D. Link the Reserved Instances to the master payer account and use Amazon Redshift Spectrum to query Detailed Billing Report data across all accounts.

Correct answer: B

Explanation

Option B is correct because AWS Organizations Consolidated Billing allows centralized billing and sharing of Reserved Instance benefits while maintaining separate resources. Option A is incorrect as it focuses on service control policies, which do not directly address billing centralization. Option C involves more complexity than necessary for billing purposes, and Option D, while possible, does not centralize billing effectively compared to the straightforward approach of Option B.
