Nokia Bell Labs 5G Foundation - BL0-100 Exam Practice Test

Question 1

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. 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.

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. 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.

Correct Answer: D

Question 2

What is Unified Data Management (UDM)?

A. This network function provides registration and discovery functionality to enable other network functions/ services to discover and communicate with each other.

B. This network function supports authentication for 3GPP and non-3GPP accesses.

C. 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.

D. 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.

Correct Answer: B

Question 3

What is the maximum distance of an Edge Cloud from end-user?

A. 5,000 KM

B. 1,000 KM

C. 300 KM

D. 10,000 KM

Correct Answer: B

Question 6

What will 5G bring in terms of supporting requirements of industry automation? (Choose three.)

A. Low latency characteristics in the range of 50 to 100 ms for Discrete and Process Automation Applications.

B. Low latency characteristics in the range of 5 to 10 ms for High Speed Discrete Automation Applications.

C. Low latency characteristics in the range of 100 to 200 ms for Remote Control Tele-operation Applications.

D. Low latency characteristics in the range of 0.1 to 1 ms for Video Monitoring and AR.

Correct Answer: A,B,C

Question 7

Which of the following defines a vertical Network Slice?

A. When it serves a given common purpose, for a use case with a defined QoS (eg a use case in transportation, in energy).

B. When it operates on the same layer of the ISO/OSI model.

C. When it serves a given customer for a specific purpose, such as a national energy network.

D. When it cross all the network layers from the radio up to the core.
