Question: What are the primary procedures supported by the "Subscribe_VRUZoneManagement" service operation in the context of VAE Services?
Option 1: Only VRU Zone Management Subscription Creation for new VASS instances.
Option 2: Solely VRU Zone Management Subscription Deletion for terminating services.
Option 3: VRU Zone Management Subscription Creation, Update, and Deletion collectively.
Option 4: Just VRU Zone Management Subscription Update for existing subscriptions.
Explanation: The correct answer is Option 3 because the "Subscribe_VRUZoneManagement" service operation is designed to handle multiple lifecycle aspects of a VRU Zone Management Subscription. This includes creating new subscriptions (to onboard new services or areas), updating existing ones (to reflect changes in service needs or geographical boundaries), and deleting them (when services are no longer required). Supporting all three procedures (Creation, Update, and Deletion) ensures flexibility and comprehensive management of VRU Zones within the VAE Server for various service consumers like VASS.
