A rental car company wants to offer a service to their clients where the renter can leave a self-driving car wherever they want when the rental period is up. A company operator will then remotely drive the left vehicles back to the rental location. Where should the application for remote car control and driving reside and why?

A.

It should run in the central cloud as latency is not very important here. Reliability is guaranteed by the central cloud.

B.

The application should run in the central cloud, with very high access throughput to support low latency.

C.

It should be installed locally on the car computer and the company operator should remotely connect to it. This approach is more secure.

D.

It should be running in the edge cloud because latency is very important for the remote control of vehicles in motion and also for reliability purposes.

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

A.

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

B.

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

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 50 to 100 ms for Discrete and Process Automation Applications.

Many 5G use cases require the network to provide very high capacity in the order of 10 Gb/s. What are the 3 different methods that can be used to increase capacity in the wireless interface?

A.

more cells

bigger cells

more spectrum

B.

more cells

high energy

more antennas

C.

more spectrum

high spectral efficiency

higher cell density

D.

use higher spectrum bands

restrict number of devices connected wirelessly

bigger cells

What functionality is applied by SDN to find an alternative path in case of failure in the Transport Network?

A.

Path Correlation Engine

B.

Alternative Route Finding

C.

Alternative Path Computing

D.

Path Computation Engine

Which standards organization defines the EAP protocol?

A.

IETF

B.

ITU

C.

ETSI

D.

3GPP

Which of the following are the elements that drive Access capacity growth? (Choose three.)

A.

Support of wireless backhauling

B.

Integration of 4G and Wi-Fi radio in 5G access

C.

More micro, small and ultra-small cells

D.

5G Home box can provide 5G wireless access

What is the Unstructured Data Storage Function (UDSF)?

A.

This network function exposes 5G Core Network functionalities available to 3rd parties, so that 3rd party capabilities and events may be securely exposed by the Network Exposure Function (NEF).

B.

This network function is part of data repositories in the Common Data Layer. It stores 3GPP standardized data.

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.

Your manager started a brainstorming session during a meeting on how automation can be driven in the network. He asks what tools can be used to increase automated services in the network. What would you answer be?

A.

We need to find a software company that will write software to automate the network services.

B.

We can create rule-based automation. We can also use Artificial Intelligence and Machine Learning to automate all network services.

C.

We can write scripts that will be executed at certain times when a specific event happens and the service will be automated in this way.

D.

We can use big data. It is the main tool that should be used for network automation.

New virtual machines are deployed to support higher leak load for an existing VNF. What is this type of scaling called?

A.

Spatial

B.

Data Center

C.

Vertical

D.

Horizontal

You have a trainee at your company and you are mentoring him. The trainee came across the term "Network Slicing”. He asks you what is "Network Slicing" and why do we need it?

A.

Network Slicing is just like the OSI model. It is the division of the network into layers horizontally from the physical to the application. It is needed to specify which layer a service resides.

B.

Network Slicing is a technology that allows the network to serve applications with different sets of requirements in terms of latency, reliability, capacity, density, and such. Every application has a set of requirements different from others. With network slicing, we give every application what it needs from the network.

C.

Network Slicing is an end-to-end “virtual private service”, extending across access, transport, core, and cloud. It is a general term used to define in which piece of the network we are.

D.

Network slicing is a new technology to divide the network among users. It is needed for confidentiality purposes.

How is a slice identified in the network?

A.

By the single network slice assistance information (S-NSSAI).

B.

By the QoS class ID (QCI).

C.

By the assigned customer and the slice IDs (CU-S-ID).

D.

By the customer ID (CU-ID).

Which deployment option is used by initially deployed 5G non-standalone networks?

A.

Option 4

B.

Option 2

C.

Option 3x

D.

Option 7

What does 5G bring to Industry 4.0? (Choose two.)

A.

5G will generate a huge amount of data and Information Technology will provide the computing platform with analytics and AI.

B.

5G provides the connectivity (bandwidth, latency and reliability) needed to exchange data for OT and IT functionality.

C.

5G brings nothing to Industry 4.0.

D.

5G will generate a huge amount of data with mMTC and IT platforms are expected to suffer from this.

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

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.
