Question: What is the primary purpose of the Config_PC5ProvisioningRequirement service operation in the context of V2X (Vehicle-to-Everything) communications, as facilitated by a VAE (V2X Application Enabler) server?
Option 1: To establish a UE (User Equipment) to VAE server connection for voice services.
Option 2: To manage the lifecycle of V2X application subscriptions.
Option 3: To retrieve real-time traffic updates from the network.
Option 4: To provide a V2X PC5 (Proximity-based Services using PC5) provisioning requirement to the VAE server for configuration.
Explanation: The correct answer reflects the service operation's defined purpose: to enable a service consumer to communicate its specific provisioning needs for PC5-based services to the VAE server, crucial for configuring seamless V2X communications over the PC5 interface for proximity-based services like vehicle-to-vehicle (V2V), vehicle-to-pedestrian (V2P), etc. The other options are incorrect as they relate to unrelated services.
