Question: What is the significance of the Application-ID value (16777303) for the Sd Application in Diameter protocol, as per 3GPP specifications?
Option 1: It identifies the UE's (User Equipment) supported wireless network technologies.
Option 2: It specifies the QoS (Quality of Service) parameters for a particular bearer service.
Option 3: It determines the security protocol used for encrypting Sd Application messages.
Option 4: It uniquely identifies the Sd Application in the Diameter command header and AVPs, distinguishing it from other applications.
Explanation: The correct answer is Option 4 because, according to 3GPP specifications, the Application-ID (16777303) is crucial for identifying the Sd Application within the Diameter protocol framework. This unique identifier ensures that commands and AVPs are correctly associated with the Sd Application, facilitating proper communication and policy control in telecom networks.
