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 in a computer network that handles authentication requests and verifies users trying to access resources within a domain. It is a key component of the Active Directory environment.

• It stores user account information and security details.
• It authenticates logins and enforces security policies for users and computers.
• Without a domain controller, centralized authentication and access control are not possible in a domain-based network.

This makes it a core part of enterprise IT infrastructure.
