A team is designing a system where a sensor must send a reading to a cloud server and receive an immediate acknowledgement that the data was received. The sensor is not battery-constrained but the network is unreliable. Which protocol and QoS setting is most appropriate?

CoAP with non-confirmable messages

A weather monitoring network generates 1 TB of raw sensor data per day. The data is used for real-time forecasting and climate research. The research team needs to query historical data for the past 10 years. The budget is constrained. Which data management strategy is most appropriate?

Store all data in object storage and query it directly

Store recent data in a time-series database and archive older data to object storage with lifecycle policies

Delete data older than one year to save costs

Store all data in a time-series database for 10 years

A manufacturing plant has 200 machines generating vibration data at 100 Hz. The plant has a reliable local network but a limited WAN link to the cloud. The goal is to run predictive maintenance models that require historical data from all machines. The models are updated monthly. The plant also needs real-time alerts for critical failures. Which architecture best balances latency, bandwidth, and model accuracy?

Perform edge analytics for real-time alerts and send only aggregated features to the cloud for model training

Send all raw vibration data to the cloud for both real-time alerts and model training

Run all analytics on the edge and never send data to the cloud

Use a batch upload of raw data every night and process alerts only during the day

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.
