- Risk Analysis
- Risk Assessment
- Risk Identification
- Risk Mitigation
In IoT projects, the phase where potential risks and challenges are identified is known as "Risk Identification." This process involves recognizing and documenting possible issues that could impact the project's success.
In the context of IoT healthcare applications, remote patient monitoring primarily employs which communication model?
- Peer-to-Peer Communication
- Cellular (3G/4G/5G) Communication
- Star Network Communication
- Satellites Communication
In IoT healthcare applications, remote patient monitoring primarily employs Cellular (3G/4G/5G) Communication. Cellular networks offer widespread coverage and reliable connectivity for transmitting patient data to healthcare providers, ensuring that critical health information can be monitored in real-time.
In a typical Wireless Sensor Network (WSN), the sensor nodes primarily:
- Collect and process data
- Power the network
- Receive data only
- Transmit data only
In a typical WSN, sensor nodes collect and process data. These nodes are responsible for sensing the environment, processing the collected data, and transmitting relevant information to the base station or other nodes in the network.
One of the primary reasons IoT devices use low-power modes is to ________.
- Achieve faster data transfer
- Conserve battery life
- Enhance device connectivity
- Improve data security
One of the primary reasons IoT devices employ low-power modes is to conserve battery life. IoT devices are often deployed in remote or inaccessible locations where changing batteries can be challenging, so optimizing power consumption is crucial.
Which technology primarily supports the vast amount of data generated by IoT devices?
- Bluetooth
- Cloud computing
- RFID
- Wi-Fi
Cloud computing is the technology that primarily supports the vast amount of data generated by IoT devices. IoT devices generate enormous quantities of data, and cloud platforms provide scalable and flexible infrastructure for storing, processing, and analyzing this data. Cloud computing also enables remote access and real-time monitoring of IoT devices.
A company discovered that their IoT devices were participating in a DDoS attack without their knowledge. This is likely due to:
- Inadequate firmware updates
- Lack of security measures
- Overuse of battery power
- Poor network connectivity
A company's IoT devices participating in a DDoS attack could be due to a lack of proper security measures. IoT devices, if not adequately secured, can be vulnerable to malicious actors who compromise their operation and use them as bots in a DDoS attack. Ensuring security measures like encryption, strong authentication, and regular security updates is crucial in such cases.
Which of the following is a common security threat to IoT devices?
- Data breaches
- Excessive battery usage
- High processing power
- Poor Wi-Fi connectivity
Data breaches are a common security threat in IoT, as unauthorized access to IoT data can have serious consequences, such as privacy violations and misuse of sensitive information.
AI algorithms that enable IoT devices to learn from data and improve over time are known as ________.
- Deep Learning
- Machine Learning
- Reinforcement Learning
- Self-Improving Algorithms
In the context of IoT, AI algorithms that enable devices to learn from data and enhance their performance over time are referred to as "Reinforcement Learning" algorithms. These algorithms learn by trial and error, which is valuable in IoT applications.
Wearable devices that provide feedback to users about their health metrics primarily use the ________ communication model.
- Bluetooth
- Feedback
- Internet
- Telepathic
Wearable devices primarily use the "Bluetooth" communication model to send health metrics and data to the user's smartphone or other devices. Bluetooth is a short-range wireless communication technology commonly used in wearables for connectivity.
Which sensor would be most appropriate for monitoring the shipment of perishable goods to ensure they remain within a safe temperature range?
- Light sensor
- Pressure sensor
- Proximity sensor
- Temperature sensor
A temperature sensor would be the most appropriate choice for monitoring the shipment of perishable goods. Temperature sensors, often referred to as thermometers or thermocouples, measure the temperature of their surroundings. In this context, they are crucial for ensuring that perishable items remain within a safe temperature range during transportation, such as in refrigerated trucks or containers.
