Question: In a V2X (Vehicle-to-Everything) application scenario, as per 3GPP specifications, what is the requirement for using HTTP/1.1 versus HTTP/2 over TLS?
Option 1: Support of both HTTP/1.1 and HTTP/2 is mandatory over TLS.
Option 2: Support of HTTP/1.1 over TLS is mandatory, while support of HTTP/2 is recommended.
Option 3: Support of HTTP/2 over TLS is mandatory for all V2X application servers.
Option 4: The use of HTTP/1.1 or HTTP/2 over TLS is optional for V2X applications.
Explanation: This answer reflects the nuanced understanding of the specifications, highlighting that while there's a baseline requirement (HTTP/1.1 over TLS being mandatory), there's also flexibility and future-proofing with the recommendation of HTTP/2, which may offer performance enhancements but isn't yet universally required for all V2X application servers.
