Internet of Things (IoT) Practice Exam 2025 – Comprehensive Prep Resource

Gateways can indeed perform pre-processing of data from sensors, making this statement true. This functionality is crucial in Internet of Things (IoT) systems, where data generated by numerous sensors can be voluminous and complex. By implementing pre-processing at the gateway level, unnecessary data transfer to the cloud or central servers can be minimized, thereby saving bandwidth and reducing latency.

Pre-processing may involve filtering out noise, aggregating data, or even conducting initial analyses to ensure that only valuable or relevant information is sent for further processing or storage. This capability enhances overall system efficiency and ensures that the cloud isn't overwhelmed with raw data that could be processed at the edge.

Other options suggest limited scenarios for data processing that do not fully encapsulate the flexibility and utility of gateways in an IoT architecture. The first option accurately reflects the versatile role of gateways within IoT systems, empowering them to efficiently manage and streamline data flow right from the point of origin.
