WGU D415 - Software Defined
Networking Exam Questions AND
Correct Answers
\Q\.Network Functions Virtualization (NFV) - ANSWERS✔-Moved network functions from stand-
alone appliances to software running on any server, reducing the time-to-market for products.
\Q\.Software-Defined Networks (SDN) - ANSWERS✔-This architecture decouples the network
control and forwarding functions enabling the network control to become directly
programmable and the underlying infrastructure to be abstracted for applications and network
services.
\Q\.NFV Components - ANSWERS✔-Virtual Network Functions (VNFs)
Network Functions Virtualization Infrastructure (NFVI)
NFV Management and Orchestration (NFV-MANO)
\Q\.NFV Management and Orchestration (NFV-MANO) - ANSWERS✔-Consists of all functional
blocks, data repositories, reference points, and interfaces that are used for managing and
orchestrating VNFs and the NFVI.
\Q\.Network Functions Virtualization Infrastructure (NFVI) - ANSWERS✔-Is the entirety of the
hardware and software components that build the environment where VNFs are deployed.
\Q\.Virtual Network Functions (VNFs) - ANSWERS✔-Are the software implementations of
network functions.
,\Q\.Open Platform for NFV (OPNFV) - ANSWERS✔-Created by the Linux Foundation in 2014 and
is a collaborative open-source platform that seeks to develop NFV and shape its evolution.
\Q\.OpenStack - ANSWERS✔-An open-source cloud computing platform that has high market
penetration that includes a collection of interoperable modules that are used to orchestrate
large pools of compute, storage, and networking resources.
\Q\.Nova - ANSWERS✔-OpenStack compute module, is used to create and delete compute
instances as required.
\Q\.Glance - ANSWERS✔-OpenStack module that synchronizes and maintains VM images across
the com pute cluster.
\Q\.Keystone - ANSWERS✔-Module that provides authentication for accessing all OpenStack
services.
\Q\.Cinder - ANSWERS✔-OpenStack module that provides block storage used as storage
volumes for VMs.
\Q\.Swift - ANSWERS✔-OpenStack module that provides object storage that is used to store
large amounts of static data in a cluster.
\Q\.Neutron - ANSWERS✔-or networking, OpenStack module that allows the different compute
instances and storage nodes to communicate with each other.
\Q\.Horizon - ANSWERS✔-OpenStack module provides a GUI dashboard, and is by far the most
widely deployed management module.
, \Q\.Heat - ANSWERS✔-OpenStack module that helps expedite orchestration of applications
across multiple compute instances by using templates.
\Q\.Celiometer - ANSWERS✔-OpenStack module that monitors the NFVI and helps identify
bottlenecks and resource optimization opportunities.
\Q\.Ironic - ANSWERS✔-OpenStack module that is a provisioning tool for baremetal installation
of compute capabilities instead of VMs in OpenStack.
\Q\.Congress - ANSWERS✔-OpenStack module that is a policy management framework for the
OpenStack environment.
\Q\.Designate - ANSWERS✔-OpenStack module that is used to point applications in the
OpenStack environment to a trusted DNS source.
\Q\.Barbican - ANSWERS✔-OpenStack module that works with Keystone authentication to
manage internal application security by behaving as a key manager.
\Q\.Murano - ANSWERS✔-OpenStack module that provides a white list repository of
applications.
\Q\.Trove - ANSWERS✔-OpenStack module that provides a distributed database service and
enables users to deploy relational and non-relational database engines.
\Q\.Sahara - ANSWERS✔-OpenStack module formerly called Savanna, provides big data services
by providing Elastic MapReduce and ability to provision Hadoop.
