A ride-sharing company has a fleet of vehicles that send location data every 10 seconds. The number of active vehicles varies by time of day and city events. Which cloud feature is most important to handle this variable load?

Fixed-capacity virtual machines

Elastic scaling of ingestion and processing services

Manual scaling based on historical data

Which cost optimization strategy can reduce IoT cloud expenses by processing data locally and sending only relevant information to the cloud?

Increasing data retention periods

Using more expensive instance types

Sending all raw data to the cloud

A small business wants to use a cloud-based IoT platform to manage their devices without investing in hardware or software maintenance. They need to access the platform via a web browser and pay a subscription fee. Which cloud service model does this describe?

Infrastructure as a Service (IaaS)

A remote oil pipeline monitoring system has sensors that generate 500 MB per day. The site has intermittent satellite connectivity with high latency. The company needs real-time alerts for pressure anomalies and also wants to run machine learning models on historical data. Which approach is most effective?

Run anomaly detection at the edge and send only alerts and periodic summaries to the cloud for ML training

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

Store all data locally and never send to the cloud

Use a satellite link to stream all data continuously

A smart agriculture company collects temperature and soil moisture readings from thousands of sensors every minute. The data is used for real-time alerts and historical trend analysis. The cloud architect must choose a storage solution that supports high-frequency time-series writes and efficient range queries for the last 30 days, while older data is archived. Which storage approach best meets these requirements?

Store data in a message queue and process it in real time only

Use a time-series database for recent data and move older data to object storage

Use object storage for all data and query it directly

Store all data in a relational database with indexes on timestamp

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.
