CCNA 4 Chapter 7 V6.0 Answers

1. 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.

 

2. The exhibit is not required to answer the question. The exhibit shows a fog covering trees on the side of a mountain.What statement describes Fog computing?

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

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 supports larger networks than Cloud computing does.

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

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.

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

 

14. Which statement describes the concept of cloud computing?

separation of management plane from control plane

separation of operating system from hardware

separation of application from hardware

separation of control plane from data plane

server hardware needs

operating system license requirements

physical footprint

virus and spyware attacks

power and air conditioning

 

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

does not require management console software

has direct access to server hardware resources

installs directly on hardware

best suited for enterprise environments

 

17. What is an example of an M2M connection in the IoT?

Sensors in a warehouse communicate with each other and send data to a server block in the cloud.

A user sends an email over the Internet to a friend.

An automated alarm system in a campus sends fire alarm messages to all students and staff.

Redundant servers communicate with each other to determine which server should be active or standby.

 

18. What is the term for the extension of the existing Internet structure to billions of connected devices?

IoT

SCADA

digitization

M2M

 

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

Cloud computing requires hypervisor technology whereas virtualization is a fault tolerance technology.

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

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

Cloud computing separates the application from the hardware whereas virtualization separates the OS from the underlying hardware.
