Introduction to the physical structure of Active Directory
The physical structure of Active Directory refers to the use of sites and location of domain controllers, which are used to manage network traffic and conserve bandwidth.
By the end of this module, you will be able to:
The way you structure Active Directory physically determines where and when logon authentication traffic and directory replication traffic will occur.
This can have a profound effect on the performance of the network.
As you know, the physical structure is completely separate from the logical structure of the directory,
which consists of domains, trees, and forests organized on your network.
In the next lesson, we will start by discussing replication and the physical structure of Active Directory.
Define sites and site links
List reasons for creating Active Directory sites
Recognize the effect of replication traffic on a slow link
Define the relationship between sites and subnets
Define the replication components and the purpose of each
List two ways to create connection objects
Define the difference between intrasite and intersite replication
List the characteristics of site link costs
Monitor replication traffic
The Active Directory site topology is the map that describes the network connectivity, Active Directory replication guidelines, and locations for resources as they relate to the Active Directory forest.
The major components of this topology are
These are all Active Directory objects that are maintained in the forest's Configuration container; this allows the information
to be locally available on all domain controllers so the DCs can communicate properly.
- site links,
- site link bridges, and
- connection objects.
