Question 1 of 33

2. Which of the following statements about SUCI is correct?

SUCI is a temporary identifier used to hide SUPI. Under UDM contracts, it is normally a fixed identifier.

SUCI is a temporary identifier used to hide SUPI. AMF is responsible for deriving SUPI from SUCI.

Because SUCI is a temporary identifier, AMF cannot address UDM based on SUCI, so a dedicated NF must be deployed in the network to address the UDM corresponding to SUCI.

SUCI is a temporary identifier used to hide SUPI, and the corresponding SUPI is derived by UDM.

25. If the existing network is a cloud-based EPC (Engineering, Procurement, and Construction) system, and the goal is to expand into the home broadband market as quickly as possible while minimizing investment, which of the following analyses is the best choice for 5G network deployment strategy?

To avoid impacting the existing network and facilitate rapid service deployment, a new cloud-based EPC+ network will be built, with standalone networking supporting Option 3x; 5G will use a separate PLMN, making it easier for 5G terminals to select the EPC+ core network.

Upgrade the existing EPC network to an EPC+ network, and upgrade and expand the customer base of the user plane gateway. Option 3x networking is recommended, with 5G and 4G sharing a PLMN.

Upgrade the existing network to SA architecture and upgrade LTE to LTE using Opton4 network, which can quickly support 5G services.

Directly upgrade EPC to SA architecture, using Option 2 networking, to support all 5G services in one step.
