How does software-defined networking (SDN) affect
information security?
A single device can be configured for switching, routing, load
balancing, or security monitoring.
Each network function is handled by a separate, isolated
device.
With the complexity of software, carriers have little visibility
into security issues. Network information is now centralized on
one physical device. - ANSWER-A single device can be
configured for switching, routing, load balancing, or security
monitoring.
Which model involves moving services like load balancing,
firewalls, and intrusion prevention systems away from
dedicated hardware into a non-physical environment?
,Network functions virtualization (NFV)
Software as a service (SaaS)
Open systems interconnection (OSI)
Internet Engineering Task Force (IETF) - ANSWER-Network
functions virtualization (NFV)
A network utilizes virtualized environments with virtual
machines running delay-
sensitive applications. Which recommendation should be
used to protect the
virtual workload in accordance with NIST
800-125B?
Virtual firewalls should be deployed for traffic flow control
instead of physical firewalls.
Two identical bastion hosts should be used instead of one
primary host.
The logical network topology should be either a star topology
or a bus topology. - ANSWER-Virtual firewalls should be
deployed for traffic flow control instead of physical firewalls.
A virtualized network uses a subnet-level virtual firewall. Which
recommendation should be used to protect the virtual workload
in accordance with NIST 800-125B?
The firewall should be integrated with a virtualization
management platform.
,The firewall should be accessible only through a standalone
console.
The firewall should be located at the center of the network
topology.
The firewall should be reconfigured and optimized on a daily
basis. – ANSWER-The firewall should be integrated with a
virtualization management platform.
A network uses event logging for auditing purposes. How
should the audit
records be managed according to the recommendations in
NIST 800-53?
Generate time stamps for audit records.
Store audit records for a period of 36 months.
Use a designated local device for audit record storage.
Manually inspect audit records at specified intervals. -
ANSWER-Generate time stamps for audit records.
How has network functions virtualization (NFV) changed
network functions?
It has moved network functions from stand-alone appliances to
software running on any server.
It has moved network functions from software running on any
server to standalone appliances.
It has moved network functions from the network presentation
layer to the transport layer.
, It has moved network functions from the network transport
layer to the presentation layer. - ANSWER-It has moved
network functions from stand-alone appliances to software
running on any server.
Which financial benefit does network functions
virtualization (NFV) offer to
carriers?
The opportunity for pay-as-you-go services without a large up-
front investment
The opportunity to own specialized network hardware rather
than rent it
The opportunity to materially participate in and profit from
software development The opportunity for reduced complexity
and cost of network security methods - ANSWER-The
opportunity for pay-as-you-go services without a large up-front
investment
What are the software applications within a network
functions virtualization
(NFV) architecture that perform specific
network tasks?
Virtual network functions
(VNFs)
Application programming
interfaces (APIs)
