Which component contains a partial replica of all objects from every domain to facilitate searching?

• A. Domain
• B. Site
• C. Organizational Unit
• D. Global Catalog

Answer: (D)

The Global Catalog is the component that holds a partial replica of all objects from every domain to speed up searching. It stores all object classes but only a subset of attributes for each object, enough to perform fast searches across the entire forest. This allows you to locate users, groups, printers, and other resources without querying each domain controller separately, and it also supports cross-domain lookups and universal group membership resolution. In contrast, a domain contains only objects within that domain, a site relates to network topology and replication, and an Organizational Unit is just a administrative container within a domain.
