Which statement best describes the benefit of using Active Directory Domain Services in a client-server network?

• A. Increases duplicated user credentials
• B. Requires per-machine local accounts for each user
• C. Eliminates all security concerns
• D. Enables consistent authentication across resources using a directory service

Answer: (D)

Centralized identity management and consistent authentication across network resources is what Active Directory Domain Services delivers. AD DS stores user accounts, passwords, and permission data in a central directory, so when a user logs in to any domain-joined device, authentication is handled against that directory. That means the same credentials and access policies apply across file shares, applications, and services, providing a unified sign-on experience and consistent security controls. Administrators can manage accounts, passwords, and group policies from one place, which reduces fragmentation and simplifies enforcement. Other statements don’t fit because AD DS is not about duplicating credentials or forcing local machine accounts for every user; rather, it reduces local-account proliferation and centralizes credential management. And while it improves security through centralized controls, it does not eliminate all security concerns.
