A healthcare IoT solution transmits patient vital signs from wearable devices to a cloud platform. The devices use MQTT over TLS. The security team requires that each device be authenticated individually and that data be encrypted end-to-end. Which additional measure is most important to meet these requirements?

Use a shared username and password for all devices

Issue a unique X.509 certificate to each device and use it for TLS mutual authentication

Encrypt the data at the application layer before sending over MQTT

Rely on the cloud platform's firewall to restrict access

A fleet of delivery drones sends telemetry data to a cloud platform. The drones occasionally lose connectivity and need to buffer data locally until the connection is restored. The protocol must support message queuing and delivery acknowledgments. Which protocol is most suitable?

UDP without any reliability layer

A manufacturing plant has 200 machines with sensors that generate 1 GB of data per hour. The plant has a reliable but limited internet connection. The operations team needs real-time anomaly detection to stop machines immediately, but also wants to retain all raw data for long-term analysis. Which architecture best balances these requirements?

Store all data locally and never send to the cloud

Deploy edge gateways that run real-time anomaly detection and send only alerts plus summarized data to the cloud

Send all raw data to the cloud and run real-time analytics there

Use a hybrid cloud with on-premises storage and cloud batch processing

A retail chain uses IoT sensors to track foot traffic in stores. The marketing team wants to analyze customer behavior patterns over the past year. The data is stored in a cloud data lake. Which cloud service is best suited for this analysis?

A big data analytics service that can run SQL queries on the data lake

What is the primary purpose of horizontal scaling in an IoT cloud deployment?

To add more servers or instances to distribute the load

To increase the processing power of a single server

To reduce the number of devices connected

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.
