Question: What is the primary purpose of the `requestGranted` operation in the context of Delta Synchronization Integration Reference Point (IRP)?
Option 1: To initiate a full synchronization of management data between IRPManager and IRPAgent.
Option 2: To notify the IRPAgent of changes in the IRPManager's capabilities.
Option 3: To retrieve information about synchronization points for which delta sync data can be requested from the IRPAgent.
Option 4: To cancel an ongoing delta synchronization process between the IRPManager and IRPAgent.
Explanation: The `requestGranted` operation allows the IRPManager to request information about synchronization points for delta sync data from the IRPAgent, enabling targeted updates and reducing bandwidth and processing requirements for efficient telecom network management.
