The basic unit of administration in Active Directory is the domain.
4
Q
What is a domain?
A
A domain is a collection of network resources managed as a unit, sharing a common directory database and security policies.
5
Q
How are domains identified?
A
Domains are identified using DNS names, which can be either a common name or a distinguished name that includes the top-level domain.
6
Q
What is an organizational unit (OU)?
A
An OU is a container object used to subdivide and organize network resources within a domain.
7
Q
What are built-in containers?
