C. AMF retrieves the UE AM (access and mobility) and SM (session management) data from UDM.

D. AMF allocates a 5G-GUTI and includes it in the Registration Accept message sent to UE.

Which of the following actions is NOT performed during an Xn-based Inter NG-RAN Handover with I-UPF Insertion procedure?

A. AMF determines that a new I-UPF needs to be added for a PDU session.

B. SMF provides N3 tunnel info of I-UPF to target gNB via AMF.

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

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.

D. NG-RAN enforces the session-AMBR in the uplink direction.

Which of the following best describes the Secondary Node Addition procedure?

A. Used to transfer bearer contexts from the master eNB to the secondary gNB.

B. Used to establish a UE context at the gNB for a UE that supports option 3X.

C. Used to establish connectivity from the gNB to the EPC.

D. Used to establish an X2 connection between the eNB and gNB.

A. Nnrf_NFManagement_NFUpdate Request

B. Nnrf_NFDiscovery_NFDiscover Request

C. Nnrf_NFManagement_NFStatusSubscribe Request

B. A PDU session has one or more QoS Flows.

C. All QoS Flows of a PDU session are served by a single N3 GTP-U tunnel.

D. Each QoS Flow is served by a dedicated data radio bearer.

Which of the following statements most accurately describes the SDF templates used in 5G?

A. SDF templates are used by UE to map uplink traffic to QoS Flows.

B. SDF templates are used by NG-RAN to map QoS Flows to data radio bearers.

C. SDF templates are used by NG-RAN to map QoS Flows to N3 GTP-U tunnels.

D. SDF templates are used by UPF to map downlink traffic to QoS Flows.

Which of the following is NOT an advantage of the 5GS service-based architecture?

A. Application programming interfaces (APIs) are used to invoke services.

B. Service-based interfaces are point-to-point.

C. The service-based architecture enables flexible addition of new network functions and services.

D. Service producers are not aware of service consumers.

Which of the following statements about the protection of service-based interfaces (SBIs) is FALSE?

A. The transport layer security (TLS) performs certification-based authentication, providing connection security between network functions within a PLMN.

B. The OAuth 2.0 framework is used to secure the communication between network functions within a PLMN at the network layer.

C. The network domain security/Internet protocol (NDS/IP) provides confidentiality and data integrity between network functions within a PLMN.

D. The security edge protection proxy (SEPP) handles the security of inter-domain SBIs and protects the interaction between network functions in different PLMNs.
