Windows server 2012 Practice Test

Active Directory Domain Services (AD DS) is the role in Windows Server 2012 that primarily manages user access to resources. This service enables centralized management of user accounts, security, and access to resources within a domain.

AD DS provides features such as user authentication, authorization, and account management. By using AD DS, administrators can create and manage user accounts and groups, control access to resources such as files and applications, and enforce security policies across the network. This involves defining permissions and rights for users based on their roles within the organization, allowing for fine-grained control over who has access to specific resources.

In contrast, File and Storage Services supports file sharing and management but does not handle user access control directly; it's more about the management of storage itself. The Web Server (IIS) role is focused on hosting web applications and services, dealing primarily with web traffic rather than user account management. Remote Desktop Services allows remote access to desktop environments and applications but does not serve as a primary method for managing user access to resources on a network. Thus, the role of actively managing user access is best fulfilled by Active Directory Domain Services.
