Question: In a `changeMOIs` operation for managing objects in a telecom network, what is the primary purpose of the "baseObjectInstance" parameter?
Option 1: To specify the offset from the root object to the target object for each sub-operation.
Option 2: To identify the root of the object tree where changes (create, delete, update) can be made across all sub-operations.
Option 3: To define the operation type (e.g., replace, add, remove) for sub-operations within the request.
Option 4: To provide the value for attribute or attribute field modifications in sub-operations.
Explanation: The "baseObjectInstance" parameter serves as a common reference point for all sub-operations within a `changeMOIs` request, indicating the top-level object from which all changes (whether creations, deletions, or updates) are relative. This ensures that all modifications are applied within the correct context of the object tree, maintaining data integrity and adherence to model constraints.
