Question: Which of the following is a primary purpose of the "Notify_ServiceAndQoSControlInfo" service operation initiated by a VAE Server towards a subscribed service consumer in a V2X communication context?
Option 1: To notify changes in Service Requirements and QoS Adaptation, ensuring alignment between the VAE Server and the service consumer (e.g., VASS).
Option 2: To request additional resources for enhancing network coverage in densely populated areas.
Option 3: To establish a new subscription for receiving periodic updates on available V2X services.
Option 4: To terminate an existing service agreement between the VAE Server and the service consumer due to non-compliance.
Explanation: The correct answer reflects the primary purpose of this operation, maintaining synchronization between the VAE Server and subscribed entities (like VASS) regarding adaptations in service requirements and Quality of Service (QoS), ensuring seamless and efficient V2X communication services.
