Nokia Bell Labs 5G Foundation BL0-100 Exam Questions

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

MU-MIMO and beamforming

Higher spectral efficiency

Network Slicing

Multi-connectivity per User Equipment

2. Which of the following is a valid NFV attack?

Hijack attack on hypervisor

DDoS attack on the SDN switches

Poor NFV implementation

Hypervisor resources leakage

3. Which of the following statements about Network Slicing are correct? (Choose three.)

Multiple slices create multiple virtual network instances.

Unique Quality of Service can be allocated to a given slice.

Specific resources can be allocated to a given slice.

Network Slicing is a way to physically partition the common network infrastructure.

4. What is the best solution for deploying an optimal network function distribution?

Using duplicated Virtual Network Functions

Using Virtual Network Functions to control the routing

Using Virtual Network Functions orchestrated across various Cloud Data Centers

Using Virtual Network Functions in Access

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

Avoid massive database corruption

Provide real time access to the databases

Enable scalability and extreme resiliency in the 5G Core

Ensure the database integrity

6. What is Unified Data Management (UDM)?

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.

This network function supports authentication for 3GPP and non-3GPP accesses.

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.

This network function provides registration and discovery functionality to enable other network functions/services to discover and communicate with each other.

7. Which of the following is not a part of an E2E Network Slice?

Cloud Slice

Core Slice

Access Slice

Transport Slice

8. What is the primary benefit of Edge Cloud?

Lower latency

Higher Availability

Larger Bandwidth

Lower Cost

9. What are the five key features of 5G Core?

Dynamic Control plane, Adaptive Architecture, Converged-Access-Network, Stateless
and Network Self- healing

Dynamic Control plane, Service Based Architecture, Multi-Access-Network, State-efficiency and Network Slicing

Dynamic Control plane, Adaptive Architecture, Multi-Access-Network, Stateless and Network Slicing

Control and User Planes Separation, Service Based Architecture, Multi-Access-Network, State-efficiency and Network Slicing

10. Which of the following drive 5G low latency? (Choose two.)

Support of up to 1 billion of IoT and sensors devices per km2

Lower Time Transmission Interval (TTI)

Higher spectral efficiency

Edge Clouds
