Microsoft domains can be organized into trees, and trees can be organized into forests.

• A. FALSE
• B. Depends on forest functional level
• C. Not applicable
• D. TRUE

Answer: (D)

In Active Directory, domains are the basic administrative units that hold resources and policies. When several domains share a contiguous DNS namespace and are connected by trusts, they form a single tree. Multiple trees can exist, and those trees can be grouped together under one forest, which is the top-level container that provides a shared schema and global catalog across all trees. Within a forest, trusts are transitive, enabling seamless authentication and resource access across the domains in that forest. This hierarchical organization—domains into trees, trees into forests—is how Microsoft domains are structured, so the statement is true.
