A company has an organization in AWS Organizations.

SCPs are a type of organization policy that you can use to manage permissions in your organization. SCPs offer central control over the maximum available permissions for all accounts in your organization. SCPs help you to ensure your accounts stay within your organization’s access control guidelines1.

To apply an SCP to a specific set of accounts, you need to create an OU for those accounts and attach the SCP to the OU. This way, the SCP affects only the member accounts in that OU and not the other accounts in the organization. If you attach the SCP to the root OU, it will apply to all accounts in the organization, including the production account, which is not the desired outcome. If you attach the SCP to the management account, it will have no effect, as SCPs do not affect users or roles in the management account1.

Therefore, the best solutions to deploy the SCP are B and E. Option B attaches the SCP directly to the three nonproduction accounts, while option E creates a separate OU for the nonproductionaccounts and attaches the SCP to the OU. Both options will achieve the same result of restricting the EC2instance types in the nonproduction accounts, but option E might be more scalable and manageable if there are more accounts or policies to be applied in the future2.
