50 billion

Which statement describes a characteristic of a converged network?

A single network that delivers voice, video, and data to a variety of devices.

What computing platform was designed to help a beginner create interactive objects that receive input from sensors and use that input to control lights, motors, and other physical objects?

Arduino

What statement describes Fog computing?

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

What is meant by the term "Big Data"?

It describes the collection and analysis of vast stores of data for insights that can help empower decision makers.

Why is a default gateway address required in the configuration of an IP-enabled intelligent sensor?

It enables the sensor to send data to a server in a remote network.

Which statement describes the Cisco IoT System?

It is an infrastructure to manage large scale systems of very different endpoints and platforms.

What is the IoE?

It is an interconnection between people, data, process, and things to provide value.

Why is Cloud computing necessary for the management of data in the Internet of Everything?

It provides applications and services distributed over the globe.

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

Which scenario is an example of an M2M interaction in a retail IoE solution?

When a customer removes an item from the shelf, the RFID tag sends an inventory update message to the ordering management system.

What is an example of a computer program that could be coded with the JavaScript scripting language?

a mortgage monthly payment calculator on a web page

What is the Internet?

a network of networks

An employee has an idea for a product and decides to make a functioning demonstration version of the new product to show management. What is the student creating with the demonstration version?

a prototype

Which three network models are described in the fog computing pillar of the Cisco IoT System? (Choose three.)

client server, fog computing, cloud computing

In a new smart home, the refrigerator has a sensor that detects that the milk container is almost empty. To what device would this sensor send this data so that eventually a text message is sent to the home owner?

controller

Which devices collect data from sensors?

controllers

Refer to the exhibit. It shows how data can help make decisions that inform our actions. These actions create data that in turn informs the actions of devices. This is an example of a

feedback loop

The exchange of data that is generated by connected devices and causes something to change is called a

feedback loop

is software that is embedded into the read-only memory of devices such as watches and cell phones. This limited functionality software is often used to boot the device.

firmware

A few days ago, a person was browsing a website that sells sporting goods. After some time, this person receives an email from the same website about a sale on a similar item. What kind of business practice is this?​

micromarketing

Which pillar in the Cisco IoT System describes embedded networks that include compact form factor switch and router cards running Cisco IOS Software to provide secure data, voice, and video communications?

network connectivity

As IoE connections are evolving, which component will change to get the right information to the right place at the right time more efficiency?

process

Which network device maintains information on where to forward data packets to reach remote destinations?

router

Which type of device will be most responsible for the explosive growth of the IoT?

sensors

Why is a common protocol suite necessary for transmission of data over remote networks?

to ensure the interoperability of devices from various vendors

A company that uses customer feedback posted on the Internet to guide the revision of support policies is an example of a company being agile.

true

RFID tags are types of wireless sensors.

true

A data center has recently updated a physical server to host multiple operating systems on a single CPU. The data center can now provide each customer with a separate web server without having to allocate an actual discrete server for each customer. What is the networking trend that is being implemented by the data center in this situation?

virtualization
