Show answer and explanation
Correct answer: B
Explanation
In an AWS Organization using consolidated billing, Reserved Instance discounts are automatically applied to the instance usage that matches the RI specifications, regardless of which account in the organization purchased the RI. This ensures cost optimization across the organization, as the discount is applied to the most relevant usage within the organization.
- A. Incorrect.
This is incorrect. While RIs are purchased in a specific account, the discount can be applied across accounts in the AWS Organization under consolidated billing.
- B. Correct.
This is correct. Reserved Instance discounts are applied to the account that uses the instance, even if it is a different account from the one that purchased the RI, provided they are part of the same AWS Organization.
- C. Incorrect.
This is incorrect. The discount is not evenly distributed; it is applied based on actual instance usage across accounts under consolidated billing.
- D. Incorrect.
This is incorrect. The RI discount is not applied to all instances indiscriminately; it is applied specifically to matching instance usage within the organization.
