An AWS Organization creates a new member account. A SysOps administrator needs to upgrade that account to AWS Business Support. Which steps should the administrator take? (Choose two.)

To upgrade the support plan for a new member account in AWS Organizations, the administrator first needs to create an IAM user with administrator privileges within that new account. This is a best practice for daily administrative tasks, as using the root user for routine operations is discouraged due to its unrestricted permissions. Once the IAM user is created and configured, the administrator can sign in to the new account using these IAM user credentials and then navigate to the AWS Support Center to change the support plan. Signing in with the account root user credentials directly to change the support plan is technically possible but not a recommended security practice. Calling the AWS Support API to change the support plan is not a standard or documented method for modifying support plans. Resetting the account root user's password is irrelevant to changing the support plan.
