Question 1 of 27
1. Question
1 pointsWhat is an example of an M2M connection in the IoT?Correct
Incorrect
Hint
The Internet of Things (IoT) connects devices that traditionally are not connected to the Internet, such as sensors and actuators. A machine-to-machine (M2M) connection is unique to the IoT in that devices are connected together and communicate with each other. These devices can send data to a server block in the cloud for analysis and further operation change. -

4. Question
1 pointsWhich three network models are described in the fog computing pillar of the Cisco IoT System? (Choose three.)Correct
Incorrect
Hint
The network models describe how data flows within a network. The network models described in the Fog computing pillar of the Cisco IoT System include: Client/Server model – Client devices request services of servers. Servers are often located locally and managed by the organization. Cloud computing model – a newer model where servers and services are dispersed globally in distributed data centers. Data is synchronized across multiple servers. Fog computing – This model identifies a distributed computing infrastructure closer to the network edge. It enables edge devices to run applications locally and make immediate decisions. -

Incorrect
Hint
Private clouds are used to provide services and applications to a specific organization and may be set up within the private network of the organization or managed by an outside organization. -
Question 12 of 27
12. Question
1 pointsHow does virtualization help with disaster recovery within a data center?Correct
Incorrect
Hint
Live migration allows moving of one virtual server to another virtual server that could be in a different location that is some distance from the original data center. -
Question 13 of 27
13. Question
1 pointsWhat is a difference between the functions of Cloud computing and virtualization?Correct
Incorrect
Hint
Cloud computing separates the application from the hardware. Virtualization separates the OS from the underlying hardware. Virtualization is a typical component within cloud computing. Virtualization is also widely used in data centers. Although the implementation of virtualization facilitates an easy server fault tolerance setup, it is not a fault tolerance technology by design. The Internet connection from a data center or service provider needs redundant physical WAN connections to ISPs. -
Question 14 of 27
14. Question
1 pointsWhich two business and technical challenges does implementing virtualization within a data center help businesses to overcome? (Choose two.)Correct
Incorrect
Hint
Traditionally, one server was built within one machine with one operating system. This server required power, a cool environment, and a method of backup. Virtualized servers require more robust hardware than a standard machine because a computer or server that is in a virtual machine commonly shares hardware with one or more servers and operating systems. By placing multiple servers within the same physical case, space is saved. Virtualized systems still need the proper licenses for operating systems or applications or both and still need the proper security applications and settings applied. -
Question 15 of 27
15. Question
1 pointsWhich statement describes the concept of cloud computing?Correct
Incorrect
Hint
Cloud computing is used to separate the application or service from hardware. Virtualization separates the operating system from the hardware. -

Hint
Type 2 hypervisors are hosted on an underlaying operating system and are best suited for consumer applications and those experimenting with virtualization. Unlike Type 1 hypervisors, Type 2 hypervisors do not require a management console and do not have direct access to hardware. -
Question 17 of 27
17. Question
1 pointsWhich is a characteristic of a Type 1 hypervisor?Correct
Incorrect
Hint
Type 1 hypervisors are installed directly on a server and are known as “bare metal” solutions giving direct access to hardware resources. They also require a management console and are best suited for enterprise environments. -
Question 18 of 27
18. Question
1 pointsHow is the control plane modified to operate with network virtualization?Correct
Incorrect
Hint
In network virtualization design, the control plane function is removed from each network device and is performed by a centralized controller. The centralized controller communicates control plane functions to each network device and each device focuses on forwarding data. -
Question 19 of 27
19. Question
1 pointsWhich technology virtualizes the network control plane and moves it to a centralized controller?Correct
Incorrect
Hint
Networking devices operate in two planes: the data plane and the control plane. The control plane maintains Layer 2 and Layer 3 forwarding mechanisms using the CPU. The data plane forwards traffic flows. SDN virtualizes the control plane and moves it to a centralized network controller. -
