Sites can be explained as physical locations that contain various AD objects. We should be able to describe these objects using their boundaries. As an example, users, computers, and network devices located in an office location in London can be treated as a site, and these can be identified as unique from similar objects located in the Seattle office. The AD site topology can be divided into four different main designs:
- Single domain-single sites: This is the most common setup for small- and medium-sized businesses. In this setup, there is one site and one domain. When we set up the first domain controller in the infrastructure, it is set up as a single domain-single site by default. This is easy to maintain.
- Single domain-multiple sites: In this setup, the infrastructure has only one domain, and it's extended to multiple sites. It can be based on different buildings...
