QUESTION NO: 2
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. B. NG-RAN marks the data packet with the proper DSCP value. C. UE maps the QoS Flow identifier to a data radio bearer based on QFI-to-DRB mapping received from NG-RAN. D. NG-RAN removes the QoS Flow identifier from the packet header and forwards the packet over the proper N3 GTP-U tunnel.

Correct Answer: A

QUESTION NO: 5
Which of the following actions is performed when an idle UE moves from 5GS to EPS and the N26 interface is used?

A. AMF selects an SGW to serve the UE, and then sets up the required S5-U and S5-C GTP tunnels on the selected SGW. B. AMF uses the EPS-GUTI derived from the UE 5G-GUTI to discover the MME, and then provides the UE context to the MME. C. UE initiates an Attach procedure and includes an EPS-GUTI derived from its 5G-GUTI. D. For any PDU session that supports interworking, the serving SMF provides an SM context that includes mapped EPS bearers to the AMF.

Correct Answer: A
