AWS Certified SysOps Administrator – Associate (legacy) — Question 599

A SysOps Administrator is analyzing how Reserved Instance discounts are allocated to Amazon EC2 instances across accounts in the company's consolidated bill.
Which AWS tool will provide the details necessary to understand the billing charges?

Answer options

• A. AWS Budgets
• B. AWS Cost and Usage report
• C. AWS Trusted Advisor
• D. AWS Organizations

Correct answer: D

Explanation

AWS Organizations enables consolidated billing, which is the foundational service used to consolidate payment and manage how Reserved Instance (RI) discount sharing is applied across multiple member accounts. While reports show individual line items, AWS Organizations manages the account hierarchy and billing preferences necessary to understand consolidated charges and RI allocation. Other options like AWS Budgets and AWS Trusted Advisor are used for cost alerts and best-practice recommendations, rather than managing consolidated billing structures.
