A smart factory collects machine vibration data to predict equipment failures. The data is stored in a time-series database. The team wants to build a model that predicts failures based on historical patterns. Which cloud service would they use?

Machine learning service (e.g., Azure ML, SageMaker)

Which cloud service model provides a customer with virtualized hardware resources, such as virtual machines, storage, and networking, while the customer manages the operating system and applications?

Infrastructure as a Service (IaaS)

What is a key cost consideration when choosing a serverless IoT backend versus a dedicated virtual machine?

Serverless may incur charges per invocation, while a VM incurs charges for the time it is running

Serverless always costs more than a VM

A developer wants to use a cloud IoT platform that provides built-in device shadows, a rules engine, and integration with other cloud services. Which platform feature is most relevant?

Device registry and shadow service

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 52 practice questions to prepare you well beyond it.
