What is Unified Data Management (UDM)?

A.

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.

B.

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

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

A.

Path Correlation Engine

B.

Alternative Route Finding

C.

Alternative Path Computing

D.

Path Computation Engine

Imagine that you are defining the 5G network requirements for the Industrial Automation of a port, what is the set of 5G technology enablers and horizontal applications that makes sense?

A.

Automation of cargo handling and integration with the logistics chain is an Autonomous Container Transport vehicles that requires 5G NR, Edge cloud and High SLA slices.

B.

Automation of cargo handling and integration with shorter ship turnaround times through improved predictability of operations is a video inspection system of important large infrastructure that requires 5G NR, FWA and High SLA slices.

C.

Automation of cargo handling and integration with the logistics chain is an Autonomous Container Transport vehicles that requires 5G NR, central cloud and FWA.

D.

Automation of cargo handling and integration with shorter ship turnaround times through improved predictability of operations is a video inspection system of important large infrastructure that requires 5G NR and central cloud.

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.

The network of the future is the key to supporting the digitization and automation of many industries. This network should support diverse requirements from different applications using it. To do that, the network should have a new architecture. Which of the following best describe the elements of the new 5G end-to-end network architecture?

A.

Wireless Access, Optical Transport, and a dedicated Core Network for wireless access running in a Central Cloud.

B.

Multiple access types (not only wireless), Optical Transport, Multi-cloud, and dedicated Core for every type of access.

C.

Public sector element, a smart city element, a health element, a transport and logistics element, and an industrial element.

D.

Massive Scale Access combining many wireless and wired access types, Smart Network Fabric as transport (combining optical and IP network elements, controlled by SDN), a Universal Adaptive Core network supporting all access types, a Multi-cloud system including central, regional, edge, public, private, and hybrid cloud, and Automation and Analytics providing flexibility in the network to serve different applications.
