Which statement best describes the Global Catalog's scope?

• A. It is a writable copy of all AD DS objects
• B. It is a partial, read-only, searchable copy of all objects in the forest
• C. It stores only user accounts
• D. It is a backup of the AD DS

Answer: (B)

Global Catalog provides a forest-wide index that enables fast searching for directory objects across domains. It holds a partial replica of every object's attributes from the entire AD DS forest, designed to include just enough information to locate objects and to resolve universal group memberships. This replica is read-only on domain controllers that host the GC role, and it is not the full set of all attributes for every object. Because it covers all objects in the forest, it allows cross-domain searches without contacting every domain controller, and it is not a backup or limited to user accounts. This description matches the idea of a partial, read-only, searchable copy of all objects in the forest.
