A smart agriculture system uses a mesh of battery-powered sensors that communicate over 6LoWPAN. The sensors run a lightweight RTOS. Which networking feature is essential for the OS to support?

A full IPv6 stack with 6LoWPAN adaptation and mesh routing

A proprietary point-to-point radio protocol

A Bluetooth Low Energy stack only

A traditional IPv4 stack with NAT

An IoT device runs an RTOS with a memory protection unit (MPU). A developer wants to ensure that a buffer overflow in one task cannot corrupt the memory of another task. Which OS feature is most directly responsible for this?

The MPU configured to enforce per-task memory regions

A secure boot process with signed firmware

A real-time scheduler with priority inheritance

A dynamic memory allocator with garbage collection

An industrial controller runs an RTOS with three tasks: a safety-critical task that must run every 10 ms, a data-logging task that can tolerate delays, and a communication task that should run regularly but not at the expense of safety. The developer needs to assign priorities. What is the correct priority assignment?

Data-logging task: highest priority; safety-critical task: medium; communication task: lowest

Safety-critical task: highest priority; communication task: medium; data-logging task: lowest

Communication task: highest priority; safety-critical task: medium; data-logging task: lowest

All tasks at the same priority with round-robin scheduling

A smart-home hub must support Wi-Fi, Bluetooth Low Energy (BLE), and Zigbee devices, and also provide a web interface for local configuration. The hub has 512 MB of RAM and a dual-core ARM Cortex-A processor. Which operating system is most appropriate for this device?

A lightweight RTOS with a custom TCP/IP stack

A general-purpose embedded Linux distribution with support for multiple network stacks

A bare-metal firmware that directly drives each radio

A real-time OS with no networking stack

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 44 practice questions to prepare you well beyond it.
