A company is connecting industrial sensors to a cloud IoT platform. They need to ensure that data transmitted from sensors to the cloud is protected from eavesdropping and tampering. Which practice is essential?

Store data in a public cloud bucket

Use MQTT without encryption for lower latency

Use TLS for all device-to-cloud communication

Use HTTP with plain text payloads

An IoT platform receives messages from devices via MQTT, validates them, and stores them for analysis. The platform also needs to trigger alerts when certain thresholds are exceeded. Which sequence of cloud components best represents this architecture?

Device gateway → message broker → stream processor → time-series database

Stream processor → device gateway → object storage

Time-series database → message broker → device gateway

Message broker → time-series database → device gateway

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.
