A. By creating a new organization in AWS Organizations, you can establish a consolidated multi-account architecture. This allows you to create and manage multiple AWS accounts for different business units under a single organization. E. Setting up AWS IAM Identity Center (AWS Single Sign-On) within the organization enables you to integrate it with the company's corporate directory service. This integration allows for centralized authentication, where users can sign in using their corporate credentials and access the AWS accounts within the organization. Together, these actions create a centralized, multi-account architecture that leverages AWS Organizations for account management and AWS IAM Identity Center (AWS Single Sign-On) for authentication and access control.

A) Using AWS Organizations allows centralized management of multiple AWS accounts in a single organization. New accounts can easily be created within the organization. E) Integrating AWS IAM Identity Center (AWS SSO) with the company's corporate directory enables federated single sign-on. Users can log in once to access accounts and resources across AWS. Together, Organizations and IAM Identity Center provide consolidated management and authentication for multiple accounts using existing corporate credentials.
