D415 Software Defined Networking Study
Guide Questions with 100% Verified Correct
Answers
Which task can be performed by an administrator using a network's automation
software?
Configuring multiple wireless access points
Which network configuration automation tool is written using C++, Clojure, and Ruby?
Puppet
How does software-defined networking (SDN) affect information security?
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)
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.
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.
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.
How has network functions virtualization (NFV) changed network functions?
It has moved network functions from stand-alone appliances to software running on any
server.
Which networking task would benefit from the use of network automation tools?
Configuring multiple wireless access points
Which task can be performed by an administrator using a network's automation
software?
Add a firewall to the network.
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
What are the software applications within a network functions virtualization (NFV)
architecture that perform specific network tasks?
Virtual network functions (VNFs)
How are network functions virtualization (NFV) and software-defined networks (SDNs)
related?
