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

A.

IPSec

B.

Access Control List

C.

SSH

D.

X25

Which of the following statements about 5G Transport is incorrect?

A.

Widely diverse end to end services will require the ability to create a Transport Slice with guaranteed SLAs.

B.

Ultra Reliable Machine to Machine communication will require dependable low latency communication.

C.

Internet of things devices will require a massive increase in network connectivity.

D.

Explosive traffic growth will require statically defined manually configured end to end QoS based services.

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

A.

1,000 KM

B.

5,000 KM

C.

10,000 KM

D.

300 KM

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.

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.

What are the benefits of the stateless or state-efficient aspects of network functions?

A.

Avoid massive database corruption

B.

Provide real time access to the databases

C.

Enable scalability and extreme resiliency in the 5G Core

D.

Ensure the database integrity

What is the primary benefit of Edge Cloud?

A.

Lower latency

B.

Higher Availability

C.

Larger Bandwidth

D.

Lower Cost

In terms of scalability, flexibility, and capacity, which of the following would overcome 4G limitations?

A.

Service based architecture, stateless network functions, Cloud-ready network functions and modular network functions.

B.

Client/Server architecture, stateless network functions, Cloud-ready network functions and modular network functions.

C.

Client/Server architecture, Cloud-ready network functions, and modular network functions.

Which of the following is not a component of the 5G Flexible RAN architecture?

A.

Radio Unit

B.

Distributed Unit

C.

Centralized Unit

D.

Optical Unit

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 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.

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

(Select 3)

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.
