Question: In a VAE (V2X Application Enabler) service utilizing CAPIF (Common API Framework), which of the following is NOT a mandatory support requirement for the VAE server when interacting with CAPIF, specifically in a centralized deployment scenario?
Option 1: Exposing APIs over CAPIF-2/2e and CAPIF-3/3e reference points
Option 2: Publishing APIs over CAPIF-4/4e reference point
Option 3: Utilizing at least one security method for authentication and authorization
Option 4: Mandatory use of CAPIF-3/3e, CAPIF-4/4e, and CAPIF-5/5e reference points for interactions between co-located CAPIF core function and API provider domain functions
Explanation: In a centralized deployment where the CAPIF core function and API provider domain functions are co-located, the interactions between these components may be independent of CAPIF-3/3e, CAPIF-4/4e, and CAPIF-5/5e reference points. This implies that strict adherence to these reference points is not mandatory in such a setup for these specific internal interactions, making Option 4 the correct answer as it incorrectly suggests a mandatory requirement that does not apply universally across all deployment scenarios.
