Microsoft Certified: Azure IoT Developer Specialty (AZ-220) Practice Test

The primary focus of an Azure IoT solution is to collect data from connected devices. This data can include telemetry such as temperature readings, humidity levels, and other sensor data generated by IoT devices. By aggregating this data, organizations can gain actionable insights that inform decision-making and improve operational efficiencies. The ability to analyze this data is critical for monitoring performance, predicting maintenance needs, and even automating responses to certain conditions.

In contrast, human feedback, market trends, and web traffic do not represent the core function of Azure IoT solutions. While these elements can be important in other contexts, they are not the main sources of data that IoT solutions aim to gather and analyze. Instead, the emphasis is on leveraging the rich streams of information coming from devices to create real-time insights and enable advanced analytics, which are fundamental to the IoT landscape.
