Question: What enforcement actions can a Traffic Detection Function (TDF) perform on detected application traffic for solicited application reporting, as requested by the Policy and Charging Rules Function (PCRF)?
Option 1: Only Usage Monitoring and Application-Based Charging
Option 2: Gating, Redirection, and Bandwidth Limitation, but not Usage Monitoring
Option 3: Gating, Redirection, Bandwidth Limitation, and additionally supports Usage Monitoring and Application-Based Charging
Option 4: None of the above; TDF only performs application detection for solicited reporting
Explanation: For solicited application reporting, a TDF performs enforcement actions like Gating, Redirection, and Bandwidth Limitation as requested by the PCRF. Additionally, it supports Usage Monitoring and Application-Based Charging, making Option 3 the comprehensive correct answer, highlighting the TDF's role in controlling and monitoring application traffic.
