+These parameters and resource type can be used as part of a wider Resource Manager template to deploy a managed domain, as shown in the following section.

 ## Create a managed domain using sample template
 
 The following complete Resource Manager sample template creates an Azure AD DS managed domain and the supporting virtual network, subnet, and network security group rules. The network security group rules are required to secure the managed domain and make sure traffic can flow correctly.
