Internet of Things (IoT) Practice Exam

Which of the following is a method to manage power in IoT devices effectively?

1. Using high-power components

2. Implementing low-power protocols

3. Reducing battery size

4. Eliminating connectivity options

The correct answer is: Implementing low-power protocols

Implementing low-power protocols is a crucial method for effectively managing power in IoT devices. These protocols are specifically designed to minimize power consumption during communication between devices. By utilizing low-power communication techniques, IoT devices can remain active longer without depleting their power sources quickly. Low-power protocols often involve strategies like sleep modes, where devices can enter a low-energy state when not actively transmitting data, and efficient data transmission techniques that require less energy. This can significantly extend the lifetime of batteries, which is essential for many IoT applications that rely on battery power and are deployed in remote or hard-to-access locations. In contrast, using high-power components directly contradicts the goal of power management, while reducing battery size might compromise the overall energy capacity and longevity. Eliminating connectivity options may conserve energy but significantly limits the functionality of IoT devices, which rely on connectivity to perform their tasks efficiently. Therefore, the implementation of low-power protocols stands out as a sustainable and effective approach to managing power in IoT systems.
