Nokia Bell Labs End-to-End 5G Foundation Certification Sample Questions:

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

A) MU-MIMO and beamforming
B) Multi-connectivity per User Equipment
C) Network Slicing
D) Higher spectral efficiency

2. 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) Increasing the access throughput might be worthwhile but applications that support a higher bit rate should also be a consideration.
C) Increasing the throughput is enough. There is no need to change the network end-to-end.
D) 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.

3. 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 can create rule-based automation. We can also use Artificial Intelligence and Machine Learning to automate all network services.
B) We need to find a software company that will write software to automate the 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.

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

A) Provide real time access to the databases
B) Avoid massive database corruption
C) Ensure the database integrity
D) Enable scalability and extreme resiliency in the 5G Core

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

A) Explosive traffic growth will require statically defined manually configured end to end QoS based services.
B) Widely diverse end to end services will require the ability to create a Transport Slice with guaranteed SLAs.
C) Ultra Reliable Machine to Machine communication will require dependable low latency communication.
D) Internet of things devices will require a massive increase in network connectivity.
