Show answer and explanation
Correct answer: C
Explanation
Reserved Instances (RIs) can provide cost savings for organizations by offering discounts on EC2 instance usage. In AWS Organizations, RIs can be shared across linked accounts to maximize these savings. However, RI sharing is not enabled by default and must be explicitly activated by configuring sharing settings at the organization level. This ensures that the purchasing organization's policies are respected and that RIs are utilized efficiently across multiple accounts.
- A. Incorrect.
Incorrect: Reserved Instances are not automatically shared. Sharing must be explicitly enabled within the organization.
- B. Incorrect.
Incorrect: Reserved Instances can be shared across accounts when sharing is enabled, not restricted to the purchasing account.
- C. Correct.
Correct: Reserved Instances can be shared across accounts in an AWS Organization, but this requires enabling RI sharing at the organization level.
- D. Incorrect.
Incorrect: Reserved Instances can indeed be shared across accounts if the proper configurations are in place.
