D. SMF provides N9 tunnel info of I-UPF to UPF PSA.

Which of the following statements about session aggregate maximum bit rate (session-AMBR) is FALSE?

A. Session-AMBR limits the aggregate bit rate provided across all non-GBR QoS Flows of a PDU session.

B. SMF calculates the session-AMBR value to be enforced.

C. The UPF that terminates the N6 interface enforces the session-AMBR value in the downlink direction.

Which of the following statements about the downlink user plane data flow in Option 3X is FALSE?

A. Data packets of bearers that do not use dual connectivity are sent from EPC to UE through eNB.

B. When NR coverage is good, data packets of bearers that use dual connectivity are sent from EPC to UE using secondary cell group bearers.

C. When NR coverage degrades, the gNB decides when to use split bearers and send some of the packets received from the core through eNB.

D. When NR coverage is poor, data packets of bearers that use dual connectivity are sent to the UE through eNB.

Which of the following actions is NOT performed when handling an uplink data packet?

A. UE maps the uplink data packet to a QoS Flow based on QoS rules received from SMF.

C. NG-RAN marks the data packet with the proper DSCP value.

D. NG-RAN removes the QoS Flow identifier from the packet header and forwards the packet over the proper N3 GTP-U tunnel.
