2. What information is conveyed by the SSID that is configured on an IoT device?

  • the registration server
  • the wireless network
  • the home gateway
  • the default gateway

Explanation: Refer to curriculum topic: 1.2.2
The SSID is used to identify the name of the wireless network which a device can join.

3. Which type of network is used to connect a company located in one area of a city to another location in a city far away?

  • MAN
  • PAN
  • WAN
  • LAN

Explanation: Refer to curriculum topic: 1.1.2
Wide-area networks (WANs) provide inter-LAN connectivity between sites.

4. True or False?
The Internet of Things will connect inanimate objects to the network with intelligent sensors.

  • false
  • true

Explanation: Refer to curriculum topic: 1.2.1

5. Which command is used to test network connectivity and provide a response to each packet received by the remote host?

  • ping
  • tracert
  • connect
  • text

Explanation: Refer to curriculum topic: 1.1.2
The ping and tracert commands are both used to test connectivity. The ping command is used to test connectivity from one network device to another network device. The tracert command is used to trace a route from the source network device to another network device.

6. What is needed in a smart home to connect sensors and smart devices to a network?

  • internet connection
  • Packet Tracer
  • Bluetooth
  • home gateway

Explanation: Refer to curriculum topic: 1.2.1
In a smart home, IoT devices connect to the network through a home gateway device.

7. Which type of wireless network is used to connect devices within a city to create a metropolitan-area network (MAN)?

  • WiMAX
  • LTE
  • ZigBee
  • Bluetooth

Explanation: Refer to curriculum topic: 1.1.2
WiMAX uses the IEEE 802.15 standard to create a metropolitan-area network (MAN) within a city. Bluetooth and ZigBee are used to create a personal-area network (PAN) and LTE is used in a cellular network.

8. Which tool allows a user to simulate real networks?

  • Packet Tracer
  • artificial intelligence
  • internet
  • PAN

Explanation: Refer to curriculum topic: 1.1.1
Packet Tracer is a free network simulation and visualization tool.

9. What type of device could allow a refrigerator to place a replacement order for an item contained within it?

  • digital network
  • sensor
  • generator
  • smart phone

Explanation: Refer to curriculum topic: 1.1.1
Sensors can be used to detect motion, water levels, light levels, temperature, and other measurements such as the weight of the milk carton within a smart refrigerator that could place a replacement order for the milk.

10. What allows digital devices to interconnect and transmit data?

  • a global positioning sensor
  • a network
  • a smart phone
  • a sensor

Explanation: Refer to curriculum topic: 1.1.1
A network connects people and devices through wired or wireless means.

11. What is comprised of millions of smart devices and sensors connected to the internet?

  • the data center
  • the fog
  • the cloud
  • the Internet of Things

Explanation: Refer to curriculum topic: 1.2.1
The Internet of Things (IoT) consists of millions of smart devices and sensors connected to the Internet. The devices and sensors in the IoT collect and share data for use by business, cities, governments, hospitals and individuals.

12. What is a sensor?

  • anything that stores data
  • a device that detects or measures an event or physical property
  • something that provides products and services to customers through an internet connection
  • the foundation of the digitized world

Explanation: Refer to curriculum topic: 1.1.1
Sensors detect or measure and send that data to be processed and analyzed. Sensors can detect motion, water levels, light levels, temperature, and color.

13. What is the core component of Intent-Based Networking?

  • the internet
  • artificial intelligence
  • the cloud
  • fog computing

Explanation: Refer to curriculum topic: 1.2.2
Artificial intelligence will allow Intent-Based Networking to automatically configure network device across the network to fulfill network requirements based on the intent of those requirements.

The Internet of Things can help organizations improve the efficiency and productivity of manufacturing processes and operations.

  • true
  • false

Explanation: Refer to curriculum topic: 1.2.1

15. True or False?
Once connected to the home gateway, smart devices can be controlled from a smartphone, tablet, or PC.

  • false
  • true

Explanation: Refer to curriculum topic: 1.2.2
