A company is planning to deploy IoT devices across its infrastructure. Before doing so, it seeks certification from a recognized body to ensure the devices meet security standards. They are likely seeking certification from:
- Federal Communications Commission (FCC)
- IEEE Standards Association
- ISO/IEC 27001
- Wi-Fi Alliance
ISO/IEC 27001 is a widely recognized standard for information security management systems. Seeking certification from this body indicates a commitment to maintaining high-security standards for IoT devices.
The primary distinction between IoT security standards and regulatory compliance is:
- Focus on implementation details
- Legal requirements vs. best practices
- Network architecture vs. data integrity
- Technical specifications vs. encryption
IoT security standards primarily involve best practices and technical specifications for securing IoT devices and data, while regulatory compliance pertains to legal requirements set by authorities.
A smart city is deploying sensors throughout its infrastructure. To process data in real-time and make immediate decisions, they should consider using:
- Cloud-based servers
- Fog computing
- Traditional data centers
- Edge computing
In a smart city scenario, real-time data processing is crucial for making immediate decisions. Edge computing, which processes data closer to the data source (the sensors in this case), is the most suitable option. It reduces latency and enables quick responses, making it ideal for applications like smart cities.
A challenge in IoT device management is ensuring firmware is consistently ________ across all devices.
- Secure
- Uniform
- Updated
- Varied
In the context of IoT device management, ensuring firmware is consistently uniform across all devices is crucial. This uniformity ensures that all devices are running the same firmware version, reducing compatibility issues, vulnerabilities, and enhancing security and functionality.
LoRa technology is most suitable for:
- Long-range wireless communication
- Satellite communication
- Short-range wireless communication
- Wired communication
LoRa (Long Range) technology is ideal for long-range wireless communication. It's designed to provide low-power, long-range communication for IoT devices, making it suitable for applications where devices need to send data over considerable distances.
The use of hardcoded credentials in IoT devices can lead to:
- Better user experience
- Enhanced security
- Improved device management
- Security vulnerabilities
Hardcoded credentials, such as default usernames and passwords, can lead to serious security vulnerabilities. Attackers can easily guess or find these credentials, potentially compromising the IoT device and the network it's connected to.
What does predictive analytics in IoT primarily focus on?
- Analyzing historical data to make informed future predictions
- Collecting and storing data from IoT devices
- Monitoring real-time data for immediate action
- Securing IoT devices from cyber threats
Predictive analytics in IoT primarily focuses on analyzing historical data from IoT devices to make informed future predictions. By examining past data, IoT systems can forecast future trends, troubleshoot issues, and optimize operations.
When developing an IoT application for data-intensive tasks, which programming language offers significant advantages due to its data handling capabilities?
- C
- Python
- R
- Swift
Python is favored for data-intensive IoT applications due to its extensive libraries for data processing and analysis. It's versatile and has a large community, making it suitable for a wide range of data-related tasks in IoT. While C, R, and Swift have their strengths, Python stands out in this context.
Which technology is vital for real-time analytics in IoT deployments?
- Big data analytics
- Machine learning
- Artificial intelligence
- Stream processing
Real-time analytics in IoT deployments relies on stream processing technology. Stream processing allows IoT systems to process data as it arrives, enabling real-time analysis, monitoring, and decision-making. It is essential for handling high-velocity data from IoT devices effectively.
Early IoT was primarily focused on:
- Home automation
- Industrial automation
- Social media
- Weather forecasting
In its early stages, the Internet of Things (IoT) was primarily focused on industrial automation. It aimed to improve efficiency and monitoring in various industries by connecting machines and sensors to the internet, enabling remote monitoring and control.
