IoT Security

Correct Answer: Insufficient device configuration

The most probable cause of users receiving frequent false alarms from IoT security cameras is insufficient device configuration. Proper configuration of motion detection sensitivity, detection zones, and other settings is crucial to minimize false alarms. Incompatible power supply may cause the device to malfunction, but is less likely to specifically cause false alarms. Weak Wi-Fi signal could lead to intermittent connectivity issues, but again, this is less likely to be the direct cause of false alarms. Interference from other IoT devices might impact the camera's performance, but is also not the most likely reason for frequent false alarms. Therefore, insufficient device configuration is the best answer, as it addresses the specific issue of false alarms most directly.

Correct Answer: Incorrect data from moisture sensors

Incorrect data from moisture sensors may lead the system to overwater crops. Other answers, like pump controls and weather information, may perturb system operation, but moisture sensors directly dictate the amount of water required.

Correct Answer: Check the network for traffic congestion or interference

The most likely cause of IoT devices randomly losing network connection is network-related issues such as traffic congestion or interference. Checking the network for these problems should be the first step in troubleshooting. Testing device firmware for vulnerabilities, inspecting power sources, or adding more access points may help in certain situations, but they are less likely to be the root cause of random connection drops across multiple devices. Network congestion or interference can affect many devices simultaneously, making it the best initial focus for resolving the issue.
