In IoT architecture, the component that facilitates communication between the device layer and the processing layer is called ________.

  • Bridge
  • Broker
  • Gateway
  • Hub
In IoT architecture, the component that facilitates communication between the device layer and the processing layer is called a Broker. Brokers are responsible for routing and managing messages between IoT devices and other parts of the IoT infrastructure. They play a critical role in ensuring efficient communication and data flow within an IoT system.

The integration of AI in IoT is paving the way for:

  • Energy-efficient devices
  • Enhanced data analytics

The integration of AI in IoT is enabling enhanced data analytics, allowing IoT devices to make intelligent decisions based on vast amounts of data. This includes real-time data analysis, predictive maintenance, and more, making it a transformative aspect of IoT.

A company is developing a system where factory workers can input data about machine operations, and the machines adjust accordingly. This is an example of:

  • Artificial Intelligence
  • Augmented Reality
  • Industrial Automation
  • IoT (Internet of Things)
This scenario involves the use of sensors and data exchange to enable machines to adapt based on real-time data. It fits the category of IoT, as it involves connecting physical objects (machines) to the internet to collect and exchange data, allowing for remote monitoring and control.

When considering resource-constrained IoT devices, which programming language might be preferred due to its low-level capabilities?

  • C++
  • Java
  • JavaScript
  • Python
C++ is often preferred for resource-constrained IoT devices due to its low-level capabilities, which allow for efficient memory and resource management. Python, Java, and JavaScript are higher-level languages.

Which cloud platform provides a fully managed service to connect, process, and store data from IoT devices?

  • Amazon Web Services (AWS)
  • Google Cloud Platform (GCP)
  • Microsoft Azure
  • Microsoft IoT Hub
Microsoft IoT Hub is a fully managed service in Azure that enables secure and scalable connectivity between IoT applications and the devices it manages.

With the rapid growth of IoT devices, IPv6's ________ bit address length becomes increasingly important.

  • 128
  • 256
  • 32
  • 64
With the growth of IoT devices, IPv6's 128-bit address length is essential. This vast address space accommodates the multitude of IoT devices, preventing address exhaustion.

Which algorithm is commonly employed in predictive maintenance scenarios in IoT?

  • AES
  • Bluetooth
  • Ping
  • Random Forest
Random Forest is commonly employed in predictive maintenance scenarios in IoT. It is a machine learning algorithm used to analyze sensor data and predict when equipment or devices may fail. By monitoring the data from IoT devices, this algorithm can help in proactively addressing maintenance issues, reducing downtime, and saving costs.

A smart city initiative is planning to deploy thousands of sensors for real-time monitoring of traffic, pollution, and energy usage. The best combination of technologies for this application would be:

  • Blockchain and Artificial Intelligence
  • IoT (Internet of Things) and 5G
  • Machine Learning and Cloud Computing
  • Virtual Reality and Augmented Reality
IoT (Internet of Things) and 5G are the most suitable technologies for real-time monitoring of sensors in a smart city. IoT allows for sensor connectivity and data collection, while 5G ensures high-speed, low-latency communication. Blockchain, AI, VR, AR, Machine Learning, and Cloud Computing are important but serve different purposes in this context.

Secure boot ensures that:

  • The device boots up with trusted code
  • The device connects to the internet automatically
  • The device has a long-lasting battery
  • The device starts up quickly
Secure boot ensures that the device boots up with trusted code, protecting it from unauthorized or malicious firmware. It doesn't directly impact the device's startup speed, internet connectivity, or battery life.
