Which of the following is a benefit of using AWS Organizations?

Using AWS Organizations offers the significant benefit of enabling consolidated billing for multiple accounts under a single invoicing. This feature allows organizations to manage multiple AWS accounts more effectively by streamlining billing and cost management. With consolidated billing, all accounts within an organization can be linked, and the costs are rolled up to a central account, making it easier to monitor usage and expenses across the organization. This also enables organizations to take advantage of volume discounts, as the total usage is considered across all linked accounts.

This benefit is particularly useful for enterprises that operate multiple divisions or teams, allowing them to allocate costs accurately while simplifying their financial oversight of AWS resources. It enhances financial transparency and control, which is critical for managing budgets and expenditures within larger organizations.

The other options do not reflect the primary benefits provided by AWS Organizations. For example, while IAM roles are essential for managing permissions, they are not eliminated by using AWS Organizations. A single point of contact for all AWS services does not directly stem from using Organizations, as support and management are typically handled at the service level. Additionally, establishing a private network relates more to VPC configuration than to the organizational structure provided by AWS Organizations.
