data analytics

Cloud computing*



9. What statement describes Fog computing?

It supports larger networks than Cloud computing does.

It creates a distributed computing infrastructure that provides services close to the network edge.*

It requires Cloud computing services to support non-IP enabled sensors and controllers.

It utilizes a centralized computing infrastructure that stores and manipulates big data in one very secure data center.

10. 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?





11. Which cloud model provides services for a specific organization or entity?

a hybrid cloud

a community cloud

a public cloud

a private cloud*

12. How does virtualization help with disaster recovery within a data center?

guarantee of power

support of live migration*

supply of consistent air flow

improvement of business practices

13. What is a difference between the functions of Cloud computing and virtualization?

Cloud computing utilizes data center technology whereas virtualization is not used in data centers.

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 provides services on web-based access whereas virtualization provides services on data access through virtualized Internet connections.

14. Which two business and technical challenges does implementing virtualization within a data center help businesses to overcome? (Choose two.)

server hardware needs

physical footprint*

power and air conditioning*

operating system license requirements

virus and spyware attacks

15. Which statement describes the concept of cloud computing?

separation of application from hardware*

separation of operating system from hardware

separation of control plane from data plane

separation of management plane from control plane

16. Which is a characteristic of a Type 2 hypervisor?​

best suited for enterprise environments

installs directly on hardware

has direct access to server hardware resources

does not require management console software*

17. Which is a characteristic of a Type 1 hypervisor?​

does not require management console software

installed directly on a server​*

installed on an existing operating system​

best suited for consumers and not for an enterprise environment

18. How is the control plane modified to operate with network virtualization?

Control plane redundancy is added to each network device.

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.

The control plane on each device is interconnected to a dedicated high-speed network.

19. Which technology virtualizes the network control plane and moves it to a centralized controller?​



cloud computing

fog computing

20. 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

21. What pre-populates the FIB on Cisco devices that use CEF to process packets?

the routing table*

the ARP table

the DSP

the adjacency table

22. Which type of hypervisor would most likely be used in a data center?

Type 1*

Type 2



23. What component is considered the brains of the ACI architecture and translates application policies​?

the Nexus 9000 switch

the Application Policy Infrastructure Controller*

the Application Network Profile endpoints

the hypervisor​

24. Fill in the blank.

In an IoT implementation, devices will be connected to a “converged” network to share the same infrastructure and to facilitate communications, analytics, and management.

25. Fill in the blank.

In a scenario where a user with a laptop running the Mac OS installs a Windows virtual OS instance, the user is implementing a Type “2” hypervisor.
