Question 1

An organization recently set up an IoT network with various devices such as smart lights and thermostats. A team member noticed that unauthorized personnel have been accessing and controlling the devices. What should be done to prevent this?

Correct Answer: Implement proper authentication and authorization for IoT devices

Implementing proper authentication and authorization for IoT devices is the best approach to prevent unauthorized access and control. This involves setting up secure login credentials, access controls, and permissions for each device and user. Disconnecting all IoT devices would disrupt the intended functionality and benefits of the IoT network. Limiting the number of connected devices does not directly address the issue of unauthorized access. Replacing IoT devices with non-IoT devices would defeat the purpose of having an IoT network in the first place. Therefore, implementing strong authentication and authorization measures is the most effective way to secure the IoT network while maintaining its intended capabilities.

Question 2

A technician deployed an IoT-based monitoring system to measure temperature and humidity in an office building. After a week, the technician noticed inconsistent and inaccurate readings. What is the most likely cause and solution?

Correct Answer: Sensor calibration issues; recalibrate the sensors

The most likely cause of inconsistent and inaccurate readings in an IoT-based monitoring system is sensor calibration issues. Over time, sensors can drift out of calibration, leading to inaccurate measurements. The best solution is to recalibrate the sensors to ensure they provide accurate readings. Network latency would not typically cause inconsistent or inaccurate sensor readings, but rather delayed data transmission. While low battery levels could cause sensors to fail, it's unlikely all sensors would experience battery issues simultaneously after just one week of deployment. Faulty IoT devices are possible but less likely than calibration issues, especially if the problem appears across multiple sensors.

Question 3

A company has implemented IoT-based smart locks for their offices. Recently, several employees have complained about the delay in unlocking the doors. What is the most appropriate solution?

Correct Answer: Review network infrastructure and optimize its performance

Delays in unlocking doors may be caused by network performance issues. Reviewing network infrastructure and optimizing its performance will help to address this. Replacing locks, disconnecting devices, or imposing restrictions on device connections are not effective solutions. Repeatedly restarting the smart locks or requiring manual key entry is not practical.
