WGU D415 SOFTWARE DEFINED NETWORKING
QUESTIONS AND ANSWERS
Network Functions Virtualization (NFV) - CORRECT ANSWER✅✅Moved network functions from stand-
alone appliances to software running on any server, reducing the time-to-market for products.
Software-Defined Networks (SDN) - CORRECT ANSWER✅✅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.
NFV Components - CORRECT ANSWER✅✅Virtual Network Functions (VNFs)
Network Functions Virtualization Infrastructure (NFVI)
NFV Management and Orchestration (NFV-MANO)
NFV Management and Orchestration (NFV-MANO) - CORRECT ANSWER✅✅Consists of all functional
blocks, data repositories, reference points, and interfaces that are used for managing and orchestrating
VNFs and the NFVI.
Network Functions Virtualization Infrastructure (NFVI) - CORRECT ANSWER✅✅Is the entirety of the
hardware and software components that build the environment where VNFs are deployed.
Virtual Network Functions (VNFs) - CORRECT ANSWER✅✅Are the software implementations of
network functions.
Open Platform for NFV (OPNFV) - CORRECT ANSWER✅✅Created by the Linux Foundation in 2014 and is
a collaborative open-source platform that seeks to develop NFV and shape its evolution.
OpenStack - CORRECT ANSWER✅✅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.
,Nova - CORRECT ANSWER✅✅OpenStack compute module, is used to create and delete compute
instances as required.
Glance - CORRECT ANSWER✅✅OpenStack module that synchronizes and maintains VM images across
the com pute cluster.
Keystone - CORRECT ANSWER✅✅Module that provides authentication for accessing all OpenStack
services.
Cinder - CORRECT ANSWER✅✅OpenStack module that provides block storage used as storage volumes
for VMs.
Swift - CORRECT ANSWER✅✅OpenStack module that provides object storage that is used to store large
amounts of static data in a cluster.
Neutron - CORRECT ANSWER✅✅or networking, OpenStack module that allows the different compute
instances and storage nodes to communicate with each other.
Horizon - CORRECT ANSWER✅✅OpenStack module provides a GUI dashboard, and is by far the most
widely deployed management module.
Heat - CORRECT ANSWER✅✅OpenStack module that helps expedite orchestration of applications
across multiple compute instances by using templates.
Celiometer - CORRECT ANSWER✅✅OpenStack module that monitors the NFVI and helps identify
bottlenecks and resource optimization opportunities.
Ironic - CORRECT ANSWER✅✅OpenStack module that is a provisioning tool for baremetal installation of
compute capabilities instead of VMs in OpenStack.
Congress - CORRECT ANSWER✅✅OpenStack module that is a policy management framework for the
OpenStack environment.
, Designate - CORRECT ANSWER✅✅OpenStack module that is used to point applications in the
OpenStack environment to a trusted DNS source.
Barbican - CORRECT ANSWER✅✅OpenStack module that works with Keystone authentication to
manage internal application security by behaving as a key manager.
Murano - CORRECT ANSWER✅✅OpenStack module that provides a white list repository of applications.
Trove - CORRECT ANSWER✅✅OpenStack module that provides a distributed database service and
enables users to deploy relational and non-relational database engines.
Sahara - CORRECT ANSWER✅✅OpenStack module formerly called Savanna, provides big data services
by providing Elastic MapReduce and ability to provision Hadoop.
Manila - CORRECT ANSWER✅✅Openstack module that provides Network Area Storage (NAS) solutions
for an OpenStack deployment.
Zaqar - CORRECT ANSWER✅✅OpenStack module that provides a multi-tenant cloud messaging service.
Magnum - CORRECT ANSWER✅✅OpenStack module that is an umbrella project that provides
containerization assistance. This module is still in development.
Dynamic Host Configuration Protocol (DHCP) - CORRECT ANSWER✅✅A network management protocol
used to dynamically assign an Internet Protocol (IP) address to any device, or node, on a network so they
can communicate using IP.
UDP port number 67 - CORRECT ANSWER✅✅Destination port of a DHCP server
UDP port number 68 - CORRECT ANSWER✅✅Destination port of a DHCP client
