True
False

Question 3) True or false: Open Service Assurance addresses the service assurance barrier in the path to adoption of NFV and required service enhancements

True
False

SDN Overview

Question 1) Read the description below, then select the term that matches the description.

An architectural approach where one separates out the application layer from the control layer and also from the infrastructure layer. It’s not fixed-function logic and interfaces are all open and vendor neutral.

Software Defined Infrastructure
Network Function Virtualization
Software Defined Network

Question 2) Read the description below, then select the term that matches the description.

Takes similar concepts and broadens them to do more than just networking such as storage and compute. This type tries to achieve better efficiencies by having defining things through a software approach rather than fixed function hardware.

Software Defined Network
Software Defined Infrastructure
Network Function Virtualization

Communication Service Provider
Cloud Service Providers
Enterprises

Question 6) What are the benefits of SDN? (Select all that apply.)

Centrally managed
Agile
Directly programmable
Open standards-based and vendor neutral
Programmatically configured

Network Slicing

Question 1) True or false: One challenge of network slicing is that multiple applications and different end-to-end requirements make it difficult to implement separate networks.

True
False
