Question: What is the primary protocol to which GUP (Generic User Profile) messages are mapped for conveyance, as recommended by the 3GPP specification?
Option 1: SOAP (Simple Object Access Protocol)
Option 2: HTTP (Hypertext Transfer Protocol)
Option 3: FTP (File Transfer Protocol)
Option 4: SMTP (Simple Mail Transfer Protocol)
Explanation: The correct answer is SOAP because the specification defines and recommends a specific binding of GUP messages to the SOAP protocol for conveyance, aligning with Liberty Alliance specifications for handling message exchange within the SOAP header part.
