What defines a logical organization of resources in Active Directory?

A logical organization of resources in Active Directory is defined by an organizational unit (OU). OUs are used to group users, computers, and other resources into a hierarchical structure that reflects the organization's structure and business needs. This organizational setup allows for the delegation of administrative responsibilities and the application of group policies at different levels within the hierarchy.

For example, you might create OUs for different departments such as Sales, HR, and IT, allowing you to manage permissions and policies specific to each department without affecting others. This level of organization provides flexibility and control in managing resources within the broader context of a domain. In contrast, domains, forests, and trees represent broader structural components within Active Directory, serving as containers for OUs but not defining the logical organization itself in the same way.
