Question # 65

A company uses an organization in AWS Organizations to manage its AWS accounts. The company ' s DevOps team has developed an AWS Lambda function that calls the Organizations API to create new AWS accounts.

The Lambda function runs in the organization ' s management account. The DevOps team needs to move the Lambda function from the management account to a dedicated AWS account.
