Question: In a 5G network, when an Application Function (AF) influences SMF routeing decisions for User Plane traffic of PDU Sessions, what is the primary goal of this influence regarding user data traffic routing?
Option 1: To always prioritize traffic through a central Data Network for enhanced security
Option 2: To route user traffic according to the requirements specified by the application, potentially utilizing local access
Option 3: To bypass NEF for more direct communication between AF and UPF
Option 4: To exclusively use UPF (re)selection based on network congestion
Explanation: The correct answer reflects the key concept that AF's influence on SMF decisions aims to tailor User Plane traffic routing to meet specific application needs, which could involve directing traffic to a local access point for more efficient or context-aware handling, highlighting the importance of flexible traffic management in 5G networks to support diverse application requirements.
