Question: What happens to packets of a detected application's traffic when the corresponding uplink and/or downlink Gate Function is closed in a Policy and Charging Control (PCC) environment?
Option 1: They are buffered for later forwarding.
Option 2: They are redirected to a different network path.
Option 3: They undergo additional inspection before being forwarded.
Option 4: They are dropped and not forwarded.
Explanation: In the context of Policy and Charging Control (PCC), when the uplink and/or downlink gate for a detected application's traffic is closed, the system prevents passage of such traffic by dropping all packets belonging to the affected flow, ensuring no data is forwarded while the gate remains closed, enforcing policy decisions related to traffic management and control in telecom networks.
