Question: In the CORBA Solution Set for Bulk CM IRP, what determines the maximum number of events transmitted in a single invocation of the `push_structured_events` method?
Option 1: The size of the `EventBatch` data type defined in the OMG CosNotification module.
Option 2: A fixed value specified in the standard for all implementations.
Option 3: An IRPAgent-wide configuration parameter that controls the batch size.
Option 4: The number of Structured Events queued since the last invocation.
Explanation: The maximum number of events transmitted within a single invocation of the `push_structured_events` operation is controlled by an IRPAgent-wide configuration parameter, indicating that the batch size is dynamically configurable on the IRPAgent side.
