Which term refers to a system running a version of Windows Server with the Active Directory Domain Services role installed?

• A. Domain Controller
• B. DNS
• C. Forest
• D. Global Catalog Server

Answer: (A)

When Windows Server is running Active Directory Domain Services, that server becomes a Domain Controller for the domain. A Domain Controller stores the directory data (users, computers, groups), handles authentication and authorization, and enforces security policies for the domain. The other options describe related but distinct concepts: DNS is a separate service that AD DS relies on for name resolution, a forest is a collection of domains that share a schema and configuration, and the Global Catalog Server is a Domain Controller that holds a partial replica of all objects in the forest to speed up searches and logons. The server with the AD DS role installed is the Domain Controller because that role enables all the domain-specific directory and auth functions.
