Total questions: 27
Worksheet time: 15mins
A company uses a cloud-based payroll system. Which cloud computing technology is this company using?
infrastructure as a service (IaaS)
wireless as a service (WaaS)
software as a service (SaaS)
browser as a service (BaaS)
For a data center, what is the difference in the server virtualization data traffic compared with the traditional client-server model?
There is more data traffic flowing from virtual servers to clients.
Data traffic from clients will be routed to multiple virtual servers.
There are significant data exchanges between 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?
forwarding information base
control plane
adjacency table
data plane
Which network traffic management technology is a basic element in SDN implementations?
OpenStack
OpenFlow
Interface to the Routing System
IEEE 802.1aq
Which two technologies are core components of Cisco ACI architecture? (Choose two.)
Application Network Profile
Application Policy Infrastructure Controller
OpenFlow enabled switches
Interface to the Routing System
Transparent Interconnection of Lots of Links
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?
ITaaS
PaaS
IaaS
SaaS
Which services are provided by a private cloud?
encrypted data storage in cloud computing
secure communications between sensors and actuators
online services to trusted vendors
multiple internal IT services in an enterprise
What are two reasons an organization might use cloud computing? (Choose two.)
enables global access to corporate data
provides power and physical plants capable of meeting increased requirements
enables connectivity between disparate networks
reduces the time needed for maintenance windows
increases corporate use of technology resources
What is a characteristic of data flow processing in SDN?
The SDN controller attaches an entry to each packet to identify the flow.
The SDN controller routes a data flow first and the data plane will use policies to permit or deny the flow.
Each data flow through the network must be approved by the SDN controller first.
OpenStack is used to construct the entry in switches to facilitate data forwarding
What are three abstraction layers of a computer system? (Choose three.)
firmware
network
hardware
services
data
In software defined network architecture, what function is removed from network devices and performed by an SDN controller?
control plane
security
data plane
application policies
Which term describes the data exchanges between virtual servers in a data center?
backbone traffic
north-south traffic
vertical traffic
east-west traffic
How is the control plane modified to operate with network virtualization?
The control plane on each device is interconnected to a dedicated high- speed network.
A hypervisor is installed in each device to allow multiple instances of the control plane.
The control plane function is consolidated into a centralized controller.
Control plane redundancy is added to each network device.
Which Cloud computing service would be best for an organization that needs to collaboratively create applications and deliver them over the web?
SaaS
IaaS
ITaaS
PaaS
Which of the following is the term for the extension of the internet structure to billions of connected devices?
BYOD
Digitization
IoT
M2M
Which cloud computing service would provide the use of network hardware such as routers and switches for a particular company?
Browser as a service (BaaS)
Infrastructure as a service (IaaS)
Software as a service (SaaS)
Wireless as a service (WaaS)
What technology allows users to access data anywhere and at any time?
cloud computing
data analytics
micromarketing
virtualization
Which cloud model provides services for a specific organization or entity?
community cloud
hybrid cloud
private cloud
public cloud
What is a benefit of virtualization?
guarantee of power
improvement of business practices
supply of consistent air flow
support of live migration
Which of the following applies to a Type 2 hypervisor?
best suited for enterprise environments
does not require management console software
has direct access to server hardware resources
installs directly on hardware
What is a difference between the functions of cloud computing and virtualization?
Cloud computing provides services on web-based access, whereas virtualization provides services on
data access through virtualized internet connections.
Cloud computing requires hypervisor technology, whereas virtualization is a fault-tolerance technology.
Cloud computing separates the application from the hardware, whereas virtualization separates the OS
from the underlying hardware.
Cloud computing utilizes data center technology, whereas virtualization is not used in data centers.
Which is a characteristic of a Type 1 hypervisor?
best suited for consumers and not for an enterprise environment
does not require management console software
installed directly on a server
installed on an existing operating system
Which technology virtualizes the control plane and moves it to a centralized controller?
cloud computing
fog computing
IaaS
SDN
Which two layers of the OSI model are associated with SDN network control plane functions that
make forwarding decisions? (Choose two.)
Layer 1
Layer 2
Layer 3
Layer 4
Layer 5
Which type of hypervisor would most likely be used in a data center?
Nexus 9000 switch
Oracle VM VirtualBox
Type 1
Type 2
Which type of hypervisor would most likely be used by a consumer?
Nexus 9000 switch
Oracle VM VirtualBox
Type 1
Type 2
What component is considered the brains of the ACI architecture and translates application policies?
Application Network Profile endpoints
Application Policy Infrastructure Controller
hypervisor
Nexus 9000 switch
