Question: What is the primary purpose of the Notify_HDMapDynamicInfo service operation in V2X Application Enabler (VAE) Services?
Option 1: To request static map data from the network for vehicle navigation.
Option 2: To establish a dedicated communication channel for Vehicle-to-Everything (V2X) services.
Option 3: To notify the dynamic information updates related to High-Definition (HD) maps.
Option 4: To manage the subscription of periodic location updates from User Equipment (UE).
Explanation: The correct answer, Option 3, aligns with the specified purpose of the Notify_HDMapDynamicInfo service operation, which is to notify updates related to HD map dynamic information. This is crucial in V2X contexts for ensuring vehicles have the most current spatial awareness, enhancing safety and efficiency. Options 1, 2, and 4 are incorrect as they describe unrelated procedures not directly associated with the primary function of Notify_HDMapDynamicInfo.
