What is at the top of the Active Directory structure and consists of one or more domain trees?

• A. Domain
• B. Tree
• C. Forest
• D. OU

Answer: (C)

Forest is the top-level structure in Active Directory. It defines the security boundary and can contain one or more domain trees. All domains within a forest share the same schema and configuration and can use a single global catalog. A domain is a discrete namespace containing objects like users and computers; a tree is a collection of domains that share a contiguous DNS namespace; an organizational unit is a container inside a domain used to organize objects. So, the element at the top that can encompass multiple domain trees is the forest. If there’s only one tree, you still have a forest—just with a single tree.
