- Mandating the use of open-source software in IoT devices
GDPR primarily affects IoT devices by imposing strict data protection and privacy requirements. IoT devices often collect and process personal data, making GDPR compliance crucial.
What is the primary purpose of a secure boot in IoT devices?
- Enable remote control of the device
- Enhance battery life
- Improve device processing speed
- Protect the device from unauthorized firmware
Secure boot in IoT devices primarily aims to protect the device from unauthorized firmware, ensuring that only trusted code is executed during bootup. This helps safeguard against malicious software and unauthorized access.
What is the primary advantage of edge computing in IoT?
- Enhancing IoT device battery life.
- Increasing the range of Wi-Fi connectivity.
- Providing unlimited cloud storage for IoT devices.
- Reducing latency and processing data closer to the data source.
The primary advantage of edge computing in IoT is to reduce latency by processing data closer to the data source. This reduces the time it takes to analyze and act upon data, making it especially valuable in applications where real-time or near-real-time processing is critical.
In a typical IoT project lifecycle, post-deployment monitoring and maintenance fall under which phase?
- Deployment
- Development
- Operations
- Planning
Post-deployment monitoring and maintenance activities are part of the Operations phase in the IoT project lifecycle. This phase involves ensuring the continued functionality, security, and optimization of the deployed IoT system.
Why is 5G considered a game-changer for IoT applications?
- Limited Network Coverage
- Low Security and Privacy
- Ultra-High Data Transfer Speeds
- Widespread Compatibility
5G's ultra-high data transfer speeds are a game-changer for IoT, allowing the rapid exchange of data between devices, enabling new IoT applications.
A company is developing an IoT system for a smart city project where they need to ensure real-time communication with minimal bandwidth usage. Which protocol might they consider?
- CoAP
- HTTP
- MQTT
- WebSocket
In the context of real-time communication in IoT with minimal bandwidth usage, MQTT (Message Queuing Telemetry Transport) is a widely considered protocol. It is a lightweight publish-subscribe messaging protocol, designed for constrained devices and low bandwidth scenarios, making it a suitable choice for smart city projects.
When your smartwatch notifies you of a new message, this is an example of:
- H2M (Human-to-Machine) communication
- M2H (Machine-to-Human) communication
- M2M (Machine-to-Machine) communication
- P2P (Peer-to-Peer) communication
When your smartwatch notifies you of a new message, it's a classic example of M2H (Machine-to-Human) communication. The smartwatch (machine) is relaying information to you (human), indicating a message has arrived.
In a high-security facility, biometric devices are used for access control. To guarantee that these devices are running only authentic firmware, the facility should employ:
- Code Signing
- Firmware Updates
- Hardware Redundancy
- Intrusion Detection Systems
Code signing is essential to guarantee that biometric devices are running only authentic firmware. It verifies the authenticity and integrity of the firmware, preventing unauthorized changes. Firmware updates are important but don't guarantee authenticity. Hardware redundancy and intrusion detection systems focus on system reliability and security but not specifically firmware authenticity.
Which type of database is often preferred for IoT data storage due to its ability to handle large volumes of unstructured data?
- Flat file database
- Hierarchical database
- NoSQL database
- Relational database
NoSQL databases are often preferred for IoT data storage because they excel at handling large volumes of unstructured or semi-structured data. IoT devices generate a wide variety of data types, and NoSQL databases provide the flexibility and scalability required to store and query this data efficiently.
Which early technology played a significant role in the development of IoT concepts?
- Artificial Intelligence (AI)
- Blockchain
- Internet Protocol (IP)
- Radio Frequency Identification (RFID)
RFID technology played a significant role in the early development of IoT concepts. RFID tags and sensors allowed physical objects to be uniquely identified and tracked, which was a crucial foundation for the Internet of Things.
In which of the following applications would the M2M (Machine-to-Machine) communication model be most prevalent?
- E-commerce websites connecting customers and vendors.
- Healthcare devices monitoring patient vital signs.
- Home automation systems controlling lighting, heating, and security.
- Social media platforms for users to share photos and messages.
The M2M (Machine-to-Machine) communication model is most prevalent in applications such as home automation systems where machines (devices) communicate with each other to control various functions like lighting, heating, and security. This model is designed for seamless communication between machines to automate tasks and processes.
