D415 - Software Defined Networking Exam
Questions with 100% Verified Correct Answers
Software Defined Networking (SDN)
The use of a central control program separate from network devices to manage the flow of
data on a network
Virtual Network Functions (VNF)
The software implementations of network functions, used as modules that are deployed as the
building blocks of an NFV architecture.
Network Functions Virtualization Infrastructure (NVFI)
The entirety of the hardware and software components that make up the environment where
VNFs are deployed.
Management and Orchestration (MANO)
The framework that manages and orchestrates Virtualized Network Functions (VNFs) and
other software components. (The framework for properly deploying and interoperating VNF
in an efficient and meaningful way)
Virtualized Infrastructure Manager (VIM)
Responsible for managing and controlling NFVI hardware resources and virtual resources.
OpenFlow
The use of a central control program separate from network devices to manage the flow of
data on a network.
Open Platform for NFV (OPNFV)
,Created by the Linux foundation is 2014, this is a collaborative open-source platform that
seeks to develop NFV and shape it's evolution, with an overall objective of reducing the time-
to-market for NFV products and solutions.
OpenStack
An open-source cloud computing platform which includes a collection of interoperable
modules that are used to orchestrate large pools of compute, storage, and networking
resources.
OpenStack Core Modules
A group of OpenStack modules that are considered to be essential to operating an OpenStack
Infrastructure, which provide basic compute, networking, and storage capabilities along with
security provided by identity management.
Nova
An OpenStack core module that is used to create and delete compute instances as required.
Glance
An OpenStack core module that synchronizes and maintains VM images across the compute
cluster.
Keystone
An OpenStack core module that provides authentication for accessing all of OpenStack's
services.
Cinder
An OpenStack core module that provides block storage used as storage volumes for for VMs.
Swift
, An OpenStack core module that provides object storage that is used to store large amounts of
static data in a cluster.
Neutron
An OpenStack core module that allows the different compute instances and storage nodes to
communicate with each other.
OpenStack Management Modules
A group of OpenStack modules that enhance the MANO experience.
Horizons
An OpenStack management module that provides a GUI dashboard. By far the most widely
deployed OpenStack management module.
Heat
An OpenStack management module that helps expedite orchestration of applications across
multiple compute instances via the use of templates.
Celiometer
An OpenStack management module that monitors the NFVI and helps identify bottlenecks
and resource optimization opportunities.
Ironic
Congress
An OpenStack management module that is a policy management framework.
