• Question 24:

  Which of the following technologies drive 5G increased throughput capacity? (Choose three.)

  A. MU-MIMO and beamforming

  B. Higher spectral efficiency

  C. Network Slicing

  D. Multi-connectivity per User Equipment

  Correct Answer: ABC

• Question 25:

  What is the purpose of the secondary authentication feature?

  A. To improve authentication between the User Equipment and the 5G Core.

  B. To improve authentication when connecting to different network slices.

  C. To authenticate the User Equipment coming from an untrusted non-3GPP access (N3IWF).

  D. To authenticate the User Equipment with an external data network.

  Correct Answer: A

• Question 26:

  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.

  Correct Answer: B

• Question 27:

  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

  Correct Answer: D

• Question 28:

  What does the acronym SOAR stand for?

  A. Security Orchestration Automation and Recovery

  B. Security Optimization Accountability Recovery

  C. Security Orchestration Automation and Response

  D. Securitization, Optimization, Access Control, and Resiliency

• Question 29:

  Which one of the following requires a network service package defined in a catalog?

  A. Cloud software platform

  B. Cloud infrastructure software

  C. Cloud orchestration

  D. Software defined network

  Correct Answer: C

• Question 30:

  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.

  Correct Answer: C
