Question: In 3GPP's object-oriented modeling approach for information models, what is the term for the instantiation of a managed object class that represents a single entity within the object tree?
Option 1: Managed Object Class
Option 2: Managed Object Instance (or simply Managed Object)
Option 3: Information Element Attribute
Option 4: Unified Modeling Language (UML) Entity
Explanation: According to the object-oriented modeling approach adopted by 3GPP for designing information models, a managed object class serves as a template. The instantiation of this template to represent a specific entity within the system is referred to as a 'Managed Object Instance', or more succinctly, a 'Managed Object'. This distinction is crucial in understanding how abstract models are realized into concrete, manageable parts of an object tree in telecom management contexts.
