Question: Which of the following APIs is NOT supported by the Vs interface between the V2X application specific server and the VAE Server, but is instead supported by the VAE-E interface between VAE Servers?
Option 1: VAE_MessageDelivery
Option 2: VAE_ServiceAndQoSControlInfo
Option 3: VAE_ServiceContinuity
Option 4: VAE_V2VConfigRequirement
Explanation: The Vs interface supports various APIs for accessing services and capabilities provided by the VAE Server to the V2X application specific server, including message delivery, file distribution, and application requirements. In contrast, the VAE-E interface, which is between VAE Servers, supports APIs related to service continuity among others. VAE_ServiceContinuity is specifically mentioned as part of the VAE-E interface's supported APIs, indicating its role in ensuring continuous service between VAE Servers, rather than being directly involved with application-specific servers via the Vs interface.
