A startup is building a smart speaker that needs to process voice commands, connect to Wi-Fi, and drive a speaker amplifier. They want to minimize board space and component count. Which approach best satisfies these requirements?

Use a microcontroller with external SRAM and a separate Wi-Fi chip

Use an FPGA to implement the processor and peripherals

Use a System-on-Chip (SoC) that integrates an application processor, Wi-Fi, and audio codec on one die

Use a separate microcontroller, Wi-Fi module, and audio codec connected on a PCB

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.
