The answer is AWS Organizations with consolidated billing. This service aggregates usage and payments across all member accounts, enabling Reserved Instance discounts and Savings Plans to be shared automatically so that unused capacity from one account offsets costs in another. On the AWS Certified Cloud Practitioner CLF-C02 exam, this question tests your understanding of how consolidated billing maximizes cost savings across multiple accounts, often appearing as a scenario where a company wants to share reserved instance discounts across accounts without manual transfers. A common trap is confusing this with individual account billing or separate discount management, but remember that consolidated billing is the key enabler. Memory tip: think of consolidated billing as a “cost-sharing pool” where all accounts dip into the same bucket of reserved capacity, ensuring no discount goes to waste.
CLF-C02 Billing, Pricing, and Support Practice Question
This CLF-C02 practice question tests your understanding of billing, pricing, and support. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A company uses multiple AWS accounts managed under AWS Organizations. Which service allows them to share Reserved Instance discounts and Savings Plans across all accounts in the organization?
Why wrong: Cost Explorer visualizes and analyzes costs but doesn't enable sharing of RI discounts across accounts.
B
AWS Budgets
Why wrong: Budgets set cost and usage thresholds and alerts but don't enable discount sharing across accounts.
C
AWS Organizations with consolidated billing
Consolidated billing in Organizations automatically shares RI and Savings Plans discounts across all member accounts, maximizing discount utilization at the organization level.
D
AWS Cost and Usage Report
Why wrong: The Cost and Usage Report provides detailed billing data but doesn't enable discount sharing.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
AWS Organizations with consolidated billing
AWS Organizations with consolidated billing enables you to aggregate usage across all member accounts, allowing Reserved Instance (RI) discounts and Savings Plans to be shared. This means that unused capacity from one account can be applied to reduce costs in another account within the same organization, maximizing overall savings.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may confuse AWS Cost Explorer or AWS Budgets with cost management features that actually share discounts, but only consolidated billing within AWS Organizations provides the aggregation needed for discount sharing.
Detailed technical explanation
How to think about this question
Under the hood, consolidated billing aggregates all usage across member accounts into a single payer account, which then applies RI and Savings Plan benefits at the organization level. The sharing is automatic for most instance families, but note that regional and instance size flexibility can affect how discounts are applied; for example, a Standard RI in one account can cover usage in another account if the instance attributes match. A real-world scenario is when a development account has unused EC2 capacity from a purchased RI, and a production account in the same organization can use that discount to reduce its costs, optimizing overall spend.

Real-world example
How this comes up in practice
A startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.
