Question

Which of the following is a server that responds to authentication requests and verifies users on computer networks?

• A. AD DS
• B. Client server
• C. Domain controller
• D. PowerShell

Hint:

A Domain Controller validates user logins and controls access to network resources in domain-based systems.

Answer 1

The Correct Option is C

A Domain Controller (DC) is a server within a network that manages authentication requests and performs user verification for resource access in a domain. It is integral to the Active Directory ecosystem.

• It maintains user account data and security parameters.
• It validates logins and enforces security policies across users and devices.
• In a domain network, centralized authentication and access management are impossible without a domain controller.

This establishes it as a fundamental element of enterprise IT infrastructure.
