Question: In a Policy and Charging Control (PCC) scenario, for maximum bandwidth values higher than 2^32 bps, which of the following AVPs shall be present when the Extended-BW-NR feature is supported, to define total bandwidth usage for non-GBR QCIs at an APN?
Option 1: APN-Aggregate-Max-Bitrate-UL and APN-Aggregate-Max-Bitrate-DL
Option 2: Extended-APN-AMBR-UL and Extended-APN-AMBR-DL
Option 3: IP-CAN-Type and RAT-Type
Option 4: AVP Header: 2818 alone
Explanation: According to the specifications for Conditional-APN-Aggregate-Max-Bitrate, when maximum bandwidth values exceed 2^32 bps and the Extended-BW-NR feature is supported, the Extended-APN-AMBR-UL and Extended-APN-AMBR-DL AVPs must be present to define the total bandwidth usage in kbps for uplink and downlink directions of non-GBR QCIs at the APN, respectively. This ensures accurate policy enforcement for high-bandwidth scenarios.
