Which term is defined as a set of rules that defines the classes of objects and attributes?

• A. Schema
• B. Forest
• C. Domain
• D. Organizational Unit

Answer: (A)

The main concept here is that a schema defines the rules for what objects can exist and what attributes they can have. In directory services and databases, the schema specifies object classes (types of objects like user, group, device) and the attributes those objects may possess, along with constraints such as which attributes are required and the data types or syntax allowed. This blueprint ensures consistency when creating or updating objects across the system. For example, a user object class might require a login name and a display name, and it might define attributes like email, department, and phone number. The other terms describe organizational structures rather than the rules for objects: a forest is the collection of domains sharing a schema; a domain is a security/namespace boundary; an Organizational Unit is a container used to organize objects within a domain. So the term that fits is the schema.
