Questions with Verified 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.

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.

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
ioctl interface - CORRECT ANSWER Linux Bridge Configuration offers an interface
that can be used to create and destroy bridges in the operating system, and it can
