What kind of PoE device can be used to power a non-PoE connected object assuming PoE power is provided on the Ethernet cable?

  1. PoE midspan injector
  2. PoE endspan switch
  3. PoE coupler
  4. PoE splitter

Answer(s): D

Explanation:

PoE Splitter: A PoE splitter separates power and data from a PoE-enabled Ethernet cable, allowing the powering of non-PoE devices.
Other PoE Devices:
PoE Injector: Adds power to non-PoE Ethernet cable.
PoE Switch: Provides power directly through its ports.



What is a common characteristic of Industrial IoT (IIoT) devices that is not a characteristic of all IoT devices?

  1. Ruggedized devices constructed for operating in harsh environments
  2. Use of standardized protocols
  3. Transmission of small amounts of data throughout the day
  4. Use of proprietary protocols

Answer(s): A

Explanation:

IIoT Environments: Industrial IoT (IIoT) often involves deployment in harsh environments (factories, plants, outdoor sites) with:
Extreme temperatures
Dust & Vibrations
Exposure to chemicals or moisture
Ruggedization: IIoT devices are designed to withstand these conditions, ensuring reliability and longevity.


Reference:

IIoT: https://en.wikipedia.org/wiki/Industrial_Internet_of_things Rugged Devices: Articles on ruggedized electronics will emphasize their importance in industrial settings.



A Wi-Fi enabled weight scale is an example of what kind of health IoT device?

  1. implantable
  2. wearable
  3. non-wearable
  4. injectable

Answer(s): C

Explanation:

Health IoT Device Categories:
Wearable: Devices worn on the body (smartwatches, fitness trackers). Non-wearable: Devices used without being worn (smart scales, connected medical equipment). Implantable: Surgically inserted devices (pacemakers, glucose monitors).


Reference:

Health IoT: Resources on healthcare + IoT will illustrate device types.



In the simplified three-layer model for wireless IoT, what is the universal primary function of the Perception layer?

  1. Gathering and transmitting data to be used for actions, analysis or reporting
  2. Analyzing data for actions and reporting using AI and ML
  3. Decrypting local data to send across the unencrypted IoT network
  4. Providing the network across which data can be transmitted to the cloud

Answer(s): A

Explanation:

Perception Layer: The foundation of an IoT system, it consists of sensors and actuators that:
Sense: Collect data about the environment or object being monitored. Actuate: Potentially make changes based on commands (e.g., a smart valve opening/closing). Transmit: Send gathered data to upper layers for processing.
