Question: In 3GPP Management Service Template, what is the data type of the NRM class naming attribute 'id' and where is it typically mapped?
Option 1: Integer, mapped to an optional property of the class object
Option 2: String, mapped to a required property of the class object
Option 3: Boolean, carried as part of an 'attributes' object
Option 4: Enumerated, mapped to a standalone element in the class definition
Explanation: According to telecom management NRM specifications, the naming attribute 'id' is defined as a string type, uniquely identifying network resources. As a required property, every class object must have a defined 'id', essential for management and orchestration operations.
