Which of the following is a key benefit of using an SoC in an IoT device?

Reduced physical size and power consumption due to integration

Higher performance than any multi-chip design

Simpler replacement of individual components if one fails

Easier to upgrade the processor without changing the board

A company is designing a smart speaker that must process voice commands, stream audio, and connect to Wi-Fi. They are evaluating two SoCs: one with an integrated DSP and one without. The device is AC-powered. Which factor is most important in choosing the SoC with the integrated DSP?

The DSP provides Wi-Fi connectivity, eliminating the need for a separate radio.

The DSP offloads audio processing from the CPU, improving voice recognition performance.

The DSP increases the clock speed of the CPU, enabling faster streaming.

The DSP reduces the need for external RAM, lowering cost.

A company is developing a fleet of autonomous delivery robots that navigate indoors. Each robot needs to process camera data for obstacle detection, run a navigation algorithm, and communicate with a central server over Wi-Fi. The robots are battery-powered and need to operate for 8 hours per charge. Which processor architecture is most appropriate?

ARM Cortex-A series application processor with a GPU

RISC-V microcontroller with hardware acceleration

ARM Cortex-M series microcontroller

x86 processor with a discrete GPU

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.
