Create a dedicated Active Directory site

Question

Is this possible to create a dedicated Active Directory site for Exchange Server 2007?

Answer 1

You can install Exchange Server 2007 directly in your organization’s existing Active Directory topology. For several organizations, deploying directly in the existing Active Directory topology greatly simplifies the entire management of Exchange 2007 deployment. But, given the extensive access into domain controllers as well as global catalog servers which is needed by Exchange 2007, you might decide to make dedicated sites for your organization. You may want a dedicated site when other applications in your organization should access Active Directory domain controllers and global catalog server.
