Question: In the context of the Service Enabler Architecture Layer for Verticals (SEAL), what is the primary purpose of the `Notify_Location_Area_Monitoring_Events` API operation?
Option 1: To update UE subscription information in the network
Option 2: To manage Quality of Service (QoS) settings for specific UEs
Option 3: To inform the VAL server about UEs that have entered or left a monitored location area
Option 4: To initiate handover procedures between different RAN nodes
Explanation: The correct answer, Option 3, aligns with the described functionality of the `Notify_Location_Area_Monitoring_Events` API operation, which is specifically designed to notify the Vertical Application Layer (VAL) server about changes in the location of User Equipment (UEs), namely those moving into or out of a defined location area. This operation is crucial for vertical services that rely on location-based triggers or monitoring, ensuring the VAL server remains updated on UE locations relevant to its applications.
