Create an AD Connector in AWS Directory Service within the WorkSpaces VPC using the service account to communicate with the on- premisesActive Directory Use the AD Connector as the directory for WorkSpaces. D.Create an AWS Directory Service for Microsoft Active Directory (AWS Managed Microsoft AD) directory in the AWS Directory Service within the WorkSpaces VPC.
