Which of the following statements about Option 3X dual connectivity is FALSE?

  1. VoLTE traffic is handled by the LTE network.
  2. Dual connectivity is used for high throughput services such as eMB
  3. When NR radio quality becomes sub-optimal, gNB decides to split the bearer.
  4. Both eNB and gNB are connected with S1-U interfaces to SGW.

Answer(s): A



Which of the following statements about QoS profiles used in 5G is FALSE?

  1. SMF derives the QoS profile of a QoS Flow from a PCC rule and sends it to NG-RAN.
  2. NG-RAN uses the QoS profiles to create mapping between QoS Flow IDs and data radio bearers.
  3. NG-RAN sends the QoS profiles and corresponding QoS Flow IDs to the UE.
  4. Each QoS profile includes a 5G QoS Identifier (5QI) and an Allocation and Retention Priority (ARP).

Answer(s): C



Which of the following statements about network slice selection assistance information (NSSAI) is FALSE?

  1. Allowed NSSAI is a set of slices provided to UE by AMF during UE registration procedure.
  2. Requested NSSAI is a set of slices provided by UE to the network and contains values from serving PLMN.
  3. Subscribed NSSAI is a set of slices specified in the UE subscription data and contains only home PLMN values.
  4. Configured NSSAI is a set of slices configured on the AMF and contains slices supported per tracking area.

Answer(s): A



Which of the following statements regarding the 5G security components is FALSE?

  1. The authentication credential repository and processing function (ARPF) selects the authentication method to use for the UE.
  2. The authentication server function (AUSF) handles authentication requests for both 3GPP and non-3GPP access.
  3. The security anchor function (SEAF) makes the final decision on UE authentication.
  4. The security identifier de-concealing function (SIDF) decrypts the UE's SUCI to obtain its corresponding SUPI.

Answer(s): D

Which of the following statements about N2-based handover in 5GS is FALSE?

  1. Handover signaling messages are exchanged between source and target NG-RAN nodes through AMF.
  2. The serving AMF determines if it can continue to serve the UE and select a target AMF when required.
  3. The serving SMF determines if the UPF terminating N3 can continue to serve the UE and selects a target I- UPF when required.
  4. The SMF decides whether a direct or indirect downlink data forwarding path is to be used.

Answer(s): C
