Sites overview
Sites in AD DS represent the physical structure, ortopology, of your network. AD DS uses network topology
information, which is stored in the directory as site, subnet, and site link objects, to build the most efficient
replication topology. The replication topology itself consists of the set of connection objects that enable inbound
replication from a source domain controller to the destination domain controller that stores the connection
object. The Knowledge Consistency Checker (KCC) creates these connection objects automatically on each
domain controller. http://technet.microsoft.com/en-us/library/cc754697.aspx
********************************************************************************
You need to recommend changes to the Active Directory site topology to support on the company’s planned
changes.
Planned Changes
The company plans to implement the following changes:
· Create a child domain named sales.contoso.com. Only the domain controllers in sales.contoso.com willhost a
zone for the sales.contoso.com domain. The domain controllers in sales.contoso.com will run Windows Server
2012. The client computers in sales.contoso.com will use the sales.contoso.com domain controllers as their
DNS servers.
· Implement two servers in the Amsterdam office andtwo servers in the Paris office to replace PA1 andAMI.
These new servers will run Windows Server 2012 and will not have shared storage.
· Decommission the research.contoso.com domain. Allof the users and the Group Policy objects (GPOs) in
research.contoso.com will be migrated to contoso.com.
· Migrate the existing print queues to virtualized instances of Windows Server 2012.
· Migrate the file servers to new servers that run Windows Server 2012.
· Implement RADIUS authentication for VPN connections.
· Deploy Windows Server 2012 to all new servers.
