A team is designing a wireless soil moisture sensor that must operate for months on two AA batteries. The sensor reads data every hour and transmits it via LoRaWAN. The microcontroller spends most of its time idle. Which power management strategy is most effective for extending battery life?

Keep the CPU in active mode at all times to ensure fast response to sensor readings.

Disable all interrupts and use a polling loop to check for sensor data.

Increase the CPU clock speed to finish tasks faster and then return to idle.

Use a deep sleep mode between readings, waking only to take a measurement and transmit.

What is a System-on-Chip (SoC) in the context of IoT hardware?

A chip that integrates a CPU, memory, and peripherals into a single package

A chip that is used exclusively for wireless communication

A chip that only contains a CPU and requires external memory and peripherals

A chip that contains only non-volatile memory for firmware storage

Part of the IoT Hardware and Platforms domain, which makes up ~18% of our current practice bank. EC-Council does not publish an official question count, but from its 120-minute exam (~50–80 total, ~9–14 in this domain), expect 2–4 from this objective — we provide 48 practice questions to prepare you well beyond it.
