How many objects can you add to an Active Directory domain?

Active Directory is designed to handle a vast number of objects, encompassing users, groups, computers, and other types of resources. The correct choice indicates that there is no defined limit on the number of objects that can be added to an Active Directory domain. In practice, the maximum number of objects is primarily constrained by the performance of the server and the underlying hardware capabilities rather than a software-imposed limit.

Active Directory utilizes a hierarchical structure, allowing for a scalable design that can accommodate millions of objects across various domains in a forest. While some considerations exist, such as the performance of the domain controllers and the available resources, the architecture itself does not enforce a strict cap on the number of objects. This flexibility is one of the reasons Active Directory is widely employed in organizations of all sizes.

Therefore, while other choices specify limitations, the reality is that as long as the physical server resources can support additional objects, the Active Directory can grow substantially without an inherent limit.
