Nokia 5G Packet Core Architecture 認定 4A0-M10 試験問題:
1. Which of the following statements about the protection of service-based interfaces (SBIs) is FALSE?
A) The OAuth 2.0 framework is used to secure the communication between network functions within a PLMN at the network layer.
B) The network domain security/Internet protocol (NDS/IP) provides confidentiality and data integrity between network functions within a PLMN.
C) The transport layer security (TLS) performs certification-based authentication, providing connection security 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.
2. Which of the following statements about 5GS PDU sessions is FALSE?
A) A PDU session contains one single dedicated radio bearer and one or more N3 GTP-U tunnels.
B) A PDU session has one default QoS flow and can have multiple non-default QoS flows.
C) A PDU session has one or more UPFs acting as PDU session anchors.
D) A PDU session allows for the exchange of PDUs between UE and a data network.
3. Which of the following statements regarding the 5G security components is FALSE?
A) The security anchor function (SEAF) makes the final decision on UE authentication.
B) The security identifier de-concealing function (SIDF) decrypts the UE's SUCI to obtain its corresponding SUPI.
C) The authentication credential repository and processing function (ARPF) selects the authentication method to use for the UE.
D) The authentication server function (AUSF) handles authentication requests for both 3GPP and non-3GPP access.
4. Which of the following statements about 5G QoS Flows is FALSE?
A) A QoS Flow is the finest granularity of QoS differentiation within a PDU session.
B) A PDU session has one or more QoS Flows.
C) Each QoS Flow is served by a dedicated data radio bearer.
D) All QoS Flows of a PDU session are served by a single N3 GTP-U tunnel.
5. Which of the following statements about N2-based handover in 5GS is FALSE?
A) Handover signaling messages are exchanged between source and target NG-RAN nodes through AMF.
B) The SMF decides whether a direct or indirect downlink data forwarding path is to be used.
C) The serving SMF determines if the UPF terminating N3 can continue to serve the UE and selects a target I-UPF when required.
D) The serving AMF determines if it can continue to serve the UE and select a target AMF when required.
