In a network two topologies are there:

  1. Physical Topology: It represents the structure of the network which includes network topologies, hardware placements, IP address allocations.
  2. Logical Topology: represents the security boundaries of said network, network services etc.

In AD, the Domain represents the logical topology while Sites and Subnets represent the physical topology.

A site can be defined as a physical location or network that can be a separate building, a separate city or a separate country.

This Step-By-Step process below will provide example of configuration of sites and subnets. Here two sites, Site A and Site B will be created.

In the, SRV1 server is located in Corp. office which is situated in a different location.
