What is the Network Repository Function (NRF)?

• 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 is part of data repositories in the Common Data Layer. It stores 3GPP standardized data.
• 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 provides registration and discovery functionality to enable other network functions/services to discover and communicate with each other.

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

• Low latency characteristics in the range of 5 to 10 ms for High Speed Discrete Automation Applications.
• Low latency characteristics in the range of 0.1 to 1 ms for Video Monitoring and AR.
• Low latency characteristics in the range of 100 to 200 ms for Remote Control Tele-operation Applications.
• Low latency characteristics in the range of 50 to 100 ms for Discrete and Process Automation Applications.

Is it possible for a User Equipment to connect simultaneously to multiple slices in 5G?

• No
• Yes

What is the Authentication Server Function (AUSF)?

• This network function is part of data repositories in the Common Data Layer. It stores 3GPP standardized data.
• This network function supports authentication for 3GPP and non-3GPP accesses.
• 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).
• 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.

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

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.

When considering Cloud and Transport orchestration, evaluate whether the following statement is true or false: NFVO is to Cloud what SDN is to Transport.

• False
• True

Which one of the following solutions best reduces latency?

• Using redundant NFV resources.
• Centralizing packet switching.
• Putting applications in a centralized data center.
• Putting the application and user plane functions to the Edge or Far-Edge of the network.

Which of the following is not a 5G Transport challenge?

• Dynamic & elastic traffic patterns
• High Density and Flexible X-haul
• Explosive traffic growth
• End-to-End TDM Synchronization

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

• Path Correlation Engine
• Alternative Route Finding
• Alternative Path Computing
• Path Computation Engine
