A domain is a set of computers that the network recognizes; it is created when you install what?

• A. Active Directory
• B. DNS Server
• C. DHCP Server
• D. Windows Defender

Answer: (A)

A domain is created through a centralized directory service that manages identities and resources across many computers. In Windows environments, that service is Active Directory Domain Services (AD DS). When you install Active Directory on a server and promote it to a domain controller, you establish a domain that computers can join and that admins can manage with user accounts, groups, and policies. DNS supports AD by providing name resolution and locating services, but it isn’t what creates the domain by itself. DHCP Server assigns IP addresses, and Windows Defender is antivirus software, neither of which creates a domain.
