Question # 5

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.
