Question 1

What is an important feature of the PHP scripting language?

AIt only works on Linux systems

BIt only works embedded in web applications

CIt only works from the command line

DIt works in web applications and at the command line

Answer : D

PHP's Cross-Platform Nature:PHP originated for server-side web development, but also has a command-line interface (CLI) enabling its use for scripts and automation tasks.

Other Options:

Somelanguages are OS-specific (but less frequent with modern scripting languages) .

Many languages work in weborcommand line, notbothlike PHP.

Question 2

Which one of the following location tracking technologies is most energy efficient in typical implementations?

ABLE Beacons

BCellular

CGPS

DWi-Fi

Answer : A

BLE Beacon Power Efficiency:Bluetooth Low Energy (BLE) beacons are designed for low power consumption.Their primary function is to periodically broadcast short data packets (advertising their presence).

Other Technologies:

Cellular:More power-hungry due to long-range communication and complex protocols.

GPS:Power intensive,especially when actively tracking location.

Wi-Fi:

Question 3

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

AGathering and transmitting data to be used for actions, analysis or reporting

BAnalyzing data for actions and reporting using AI and ML

CDecrypting local data to send across the unencrypted IoT network

DProviding the network across which data can be transmitted to the cloud

Answer : A

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.

Question 4

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

Aimplantable

Bwearable

Cnon-wearable

Dinjectable

Answer : C

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).

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

Question 5

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

ARuggedized devices constructed for operating in harsh environments

BUse of standardized protocols

CTransmission of small amounts of data throughout the day

DUse of proprietary protocols

Answer : A

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.

Question 6

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

APoE midspan injector

BPoE endspan switch

CPoE coupler

DPoE splitter

Answer : D

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.

Question 7

What is most often used to track livestock on large farms and identify each animal Individually?

APhotodiode sensors

BRFID tags

C802.11 wireless radios

DThermistor sensors

Answer : B

RFID for Livestock:Radio Frequency Identification (RFID) tags are the most widely used technology for livestock tracking and individual identification on large farms.

Benefits:

Unique ID:Each RFID tag has a unique code.

Data Storage:Some tags store information about the animal.

Durability:Tags withstand outdoor conditions.

Automated Reading:Tags can be scanned quickly.
