What is typically true about a Forest in the hierarchy of domains?

In the context of Active Directory and its hierarchy, a Forest is an overarching structure that can encompass multiple domains. This aggregation allows for a unified namespace and facilitates centralized management and security policies across all the domains contained within that Forest. Each domain within a Forest can have its own set of users, groups, and policies while still being able to share resources and information with other domains in the Forest.

The Forest serves as the highest level of organization within Active Directory, as it includes the schema and configuration that governs the linked domains. This collective structure supports trust relationships, allowing for resource sharing and security boundary definitions among the included domains. Therefore, understanding that a Forest can indeed contain multiple domains is crucial for managing and networking in an Active Directory environment.
