What is the purpose of the secondary authentication feature?

• A.To authenticate the User Equipment coming from an untrusted non-3GPP access (N3IWF).
• B.To improve authentication when connecting to different network slices.
• C.To improve authentication between the User Equipment and the 5G Core.
• D.To authenticate the User Equipment with an external data network.

You and a colleague are discussing the challenges to be resolved in order to make digitization and automation a reality in all industries. He is arguing that the solution is to have faster access connectivity, but you don't agree. You are trying to convince him of the need for an end-to-end solution. The new 5G network should be built end-to-end to enable industries' quest for value. What arguments can you provide to support your position?

• A.Increasing throughput is not enough. A faster and automated transport network, a distributed cloud where applications would run depending on their latency and reliability requirements, a core network that automatically handles any type of access, and a security framework to guarantee the security in every layer of the network are also needed.
• B.Increasing the throughput is enough. There is no need to change the network end-to-end.
• C.Increasing the access throughput might be worthwhile but applications that support a higher bit rate should also be a consideration.
• D.The network consists of many layers that include access, transport, core, cloud, and all of the applications running in the cloud. Increasing throughput in access is not enough. The bit rate needs to be increased in all of the other layers as well.
