Nokia Bell Labs 5G Foundation Questions and Answers

Question 1

You are working in a logistics company. Your manager is telling you that automation is very important to create more opportunities for the company. His idea is to deliver parcels using drones. With this in mind, he asks you if a 4G network provides good connectivity for controlling the delivery drones. How would you answer him and why?

Options:

A.

Yes, 4G provides a connectivity network but, it is quite expensive. WIFI may be a preferable option.

B.

No, a 4G network is not a good choice for drone control because big operators (with whom we cannot deal) mainly deliver it.

C.

No, a 4G network cannot deliver the required connectivity. It is not able to guarantee the latency and reliability required for drone control.

D.

Yes, the drone control application can be hosted in the cloud and the 4G network can provide the speed needed to reach the application and control the drones.

Question 2

Which of the following statements are applicable to the technology of massive MIMO?

(Select 3)

Options:

A.

Several data flows are sent at the same time on the same frequency.

B.

The signals on each antenna are made orthogonal.

C.

The data flows are sent at the same time on different frequencies.

D.

Transmit diversity is used in case of poor radio conditions.

Question 3

Imagine that you are defining the 5G network requirements for the Industrial Automation of a port, what is the set of 5G technology enablers and horizontal applications that makes sense?

Options:

A.

Automation of cargo handling and integration with the logistics chain is an Autonomous Container Transport vehicles that requires 5G NR, Edge cloud and High SLA slices.

B.

Automation of cargo handling and integration with shorter ship turnaround times through improved predictability of operations is a video inspection system of important large infrastructure that requires 5G NR, FWA and High SLA slices.

C.

Automation of cargo handling and integration with the logistics chain is an Autonomous Container Transport vehicles that requires 5G NR, central cloud and FWA.

D.

Automation of cargo handling and integration with shorter ship turnaround times through improved predictability of operations is a video inspection system of important large infrastructure that requires 5G NR and central cloud.

Question 4

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?

Options:

A.

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.

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.

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.

D.

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.

Question 5

What is the best way to ensure robust slicing isolation?

Options:

A.

By implementing resource isolation and security isolation on the network slice

B.

By implementing virtual firewall on the network slice

C.

By implementing traffic isolation on the network slice

D.

By implementing user and control planes separation on the network slice

Question 6

Which function best helps reduce Edge Cloud management costs?

Options:

A.

Smart Metering

B.

Containers

C.

Orchestration

D.

Hardware acceleration

Question 7

Resource elasticity in Cloud enables which of the following actions? (Choose two.)

Options:

A.

Relocate VMs between data centers when a fault is detected.

B.

Deploy VMs across data centers when a new slice is needed.

C.

Add resources to existing VMs when traffic is high.

D.

Add VMs when traffic is high.

Question 8

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?

Options:

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.

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.

C.

Increasing the access throughput might be worthwhile but applications that support a higher bit rate should also be a consideration.

D.

Increasing the throughput is enough. There is no need to change the network end-to-end.

Question 9

In terms of universal access requirements, which of the following would overcome 4G limitations?

Options:

A.

Unified access across 3GPP and non-3GPP technologies, Multi-Access and Wireline-Wireless convergence.

B.

Universal database with unstructured data repository and Wireline-Wireless convergence.

C.

Multi-Access and Point-to-point APIs.

D.

Universal database with unstructured data repository and Wireline-Wireless convergence.
