Which cloud service model is most appropriate for running a custom machine learning model on streaming IoT data with minimal infrastructure management?

Infrastructure as a Service (IaaS)

A company runs a large IoT deployment with unpredictable traffic. They are choosing between a serverless ingestion service and a provisioned cluster of virtual machines. Which consideration is most important for cost optimization?

Serverless always costs less than VMs

Provisioned VMs are always more cost-effective for unpredictable traffic

Serverless charges per invocation and scales to zero, while provisioned VMs incur costs even when idle

Cost is not a factor in cloud IoT deployments

A smart city project deploys thousands of parking sensors. The data ingestion rate varies dramatically: low at night, high during events. The city wants to avoid paying for idle capacity but also avoid throttling during peaks. Which cloud strategy best meets these needs?

Store all data on edge devices and never scale

Use a single large VM with autoscaling disabled

Use a serverless ingestion service that scales automatically with demand

Provision a fixed number of virtual machines to handle peak load

A city deploys smart traffic cameras that must trigger immediate emergency responses when an accident is detected. The network connection to the cloud is occasionally unreliable. The solution must minimize latency and continue functioning during cloud outages. Which architecture should be implemented?

Stream all video directly to the cloud for processing

Use a cellular connection with a backup satellite link to the cloud

Run an edge gateway that performs local detection and only sends aggregated data to the cloud

Store video locally and upload it to the cloud after the incident

What is the primary purpose of data lifecycle management in an IoT cloud storage context?

To automatically move or delete data based on age and access patterns to optimize cost and compliance

To provide real-time analytics on streaming data

To encrypt all data at rest and in transit

To ensure data is replicated across multiple regions for high availability

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.
