Nokia Bell Labs End-to-End 5G Foundation Certification Sample Questions:

1. 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.

2. A company is planning to offer services to different cities worldwide so drones can be used to scan disaster areas to help identify victims' locations quickly, organize evacuations efficiently, and save lives. Drones will be connected to a 5G network. The company is planning to offer two applications running in the cloud - one to manage drones through remote control while the other offers live video streaming to drone operators. As a 5G professional, you are asked what are the network requirements for those two applications?

A) The drone control application should run through a central cloud. The video streaming application should run in the edge cloud because it carries much data, and that is expensive to run through the central cloud.
B) The drone control application needs low latency and high reliability from the network and should run in the edge cloud. The video application needs higher throughput but it is not sensitive from the latency and reliability point of view. It can run in a central cloud.
C) The drone control application needs very low latency to maneuver around obstacles, while the video application would need less latency. Both applications would be running in the central cloud.
D) Both applications should run in the edge cloud because the drone control and video applications both require low latency and high reliability from the network.

3. What is Unified Data Management (UDM)?

A) This network function is part of data repositories in the Common Data Layer and in opposition to the UDR, it stores non-standardized unstructured data.
B) This network function provides registration and discovery functionality to enable other network functions/ services to discover and communicate with each other.
C) This network function stores or retrieves subscriptions, profiles and authentication data to or from the data repositories. It offers services to the AMF, SMF, NEF and AUSF using the Service Based Interface.
D) This network function supports authentication for 3GPP and non-3GPP accesses.

4. Which of the following drive 5G low latency? (Choose two.)

A) Higher spectral efficiency
B) Lower Time Transmission Interval (TTI)
C) Edge Clouds
D) Support of up to 1 billion of IoT and sensors devices per km2

5. In a 5G Transport network, the encryption protection of the user and control plane are provided by which of the following?

A) X25
B) Access Control List
C) IPSec
D) SSH
