Question: In a Telecommunication Management context, using GDMO definitions, how are associations (except containment relations) between different object classes/instances typically modeled and accessed?
Option 1: Through specialized protocols for each relation type
Option 2: With dedicated pointers (relation role attributes) as normal object attributes, retrievable via getMoAttributes service operation
Option 3: By querying a centralized association registry using a unique identifier
Option 4: Exclusively through notification events like attributeValueChange
Explanation: In the context of Telecommunication Management and GDMO definitions, associations between different object classes or instances (excluding containment relations) are modeled using dedicated pointers. These pointers, known as relation role attributes, are treated as regular object attributes. The getMoAttributes service operation is utilized by managers to fetch the values of these association pointers, highlighting the practical application of attribute access in managing telecom network configurations.
