Which server is used to store and manage information about resources on a network and application data in a distributed database?

• A. Dynamic Host Configuration Protocol
• B. Active Directory
• C. Web Server
• D. Proxy Server

Answer: (B)

Directory services that centrally store and manage information about resources and identities on a network are what Active Directory provides. Active Directory stores and organizes details about network objects—users, computers, groups, printers, permissions, and policies—and uses a distributed database (NTDS.DIT) mounted on domain controllers that is replicated across the domain. This structure enables centralized authentication, authorization, and policy enforcement across the network. The other options describe different roles: a DHCP server assigns IP addresses automatically, a Web Server hosts web content, and a Proxy Server mediates and filters traffic. None of those maintain a centralized directory of resources with a distributed database like Active Directory does.
