There is more data traffic flowing from virtual servers to clients.
There are significant data exchanges between virtual servers.
Data traffic from clients will be routed to multiple virtual servers.
More network control traffic is generated between virtual servers and clients.
Which component in a traditional infrastructure device provides Layer 2 and Layer 3 functions to create data paths within a network?
adjacency table
forwarding information base
data plane
control plane
Which network traffic management technology is a basic element in SDN implementations?
IEEE 802.1aq
OpenStack
OpenFlow
Interface to the Routing System
What are two reasons an organization might use cloud computing? (Choose two.)
enables connectivity between disparate networks
reduces the time needed for maintenance windows
increases corporate use of technology resources
enables global access to corporate data
provides power and physical plants capable of meeting increased requirements
Which Cloud computing service would be best for a new organization that cannot afford physical servers and networking equipment and must purchase network services on-demand?
SaaS
IaaS
ITaaS
PaaS
Which services are provided by a private cloud?
encrypted data storage in cloud computing
multiple internal IT services in an enterprise
secure communications between sensors and actuators

What is a characteristic of data flow processing in SDN?
The SDN controller routes a data flow first and the data plane will use policies to permit or deny the flow.
The SDN controller attaches an entry to each packet to identify the flow.
OpenStack is used to construct the entry in switches to facilitate data forwarding.
Each data flow through the network must be approved by the SDN controller first.

services
data
network
hardware

security
application policies
Which term describes the data exchanges between virtual servers in a data center?
backbone traffic
vertical traffic
north-south traffic
east-west traffic
How is the control plane modified to operate with network virtualization?
The control plane function is consolidated into a centralized controller.
A hypervisor is installed in each device to allow multiple instances of the control plane.
Control plane redundancy is added to each network device.
The control plane on each device is interconnected to a dedicated high-speed network.
Which Cloud computing service would be best for an organization that needs to collaboratively create applications and deliver them over the web?
PaaS
IaaS
ITaaS
SaaS
Which two technologies are core components of Cisco ACI architecture? (Choose two.)

version control
provisioning
automation
orchestration
Which web service API can use multiple data formats including JSON, XML, and YAML?
XML-RPC
JSON-RPC
SOAP
REST
What are two reasons that most RESTful APIs require a key in the request? (Choose two.)
to make sure that the query matches the service offered by the web application
to specify the data format expected from the response
to authenticate the requesting source
to gather information on the people using the API
to encrypt the query message in the API request
What is a difference between the XML and HTML data formats?
XML uses a self-descriptive data structure but HTML uses a standard document structure.
XML formats data in hexadecimal whereas HTML formats data in binary.
XML requires indentation for each key/value pair whereas HTML does not require indentation.
XML encloses data within a pair of tags whereas HTML uses a pair of quotation marks to enclose data.
