AZ-220: Microsoft Azure IoT Developer Practice Test Original
With this exam you will be tested your working knowledge for Az-220. Below is the outline of the exam which you will be testedResponsibilities for an Azure IoT Developer include managing the device lifecycleset up, configuration, and maintenanceusing cloud services and other tools. You implement designs for Azure IoT solutions including device topology, connectivity, debugging, and security, as well as solutions to manage, monitor, and transform IoT-related data pipelines. You also deploy Azure IoT Edge components and configure device networking on the edge. An Azure IoT Developer works with data engineers and other stakeholders to ensure successful business integration. A candidate for this exam should have experience implementing the Azure services that form an IoT solution, including data storage options, data analysis, data processing, and platform-as-aservice options. This role should also be able to recognize Azure IoT service configuration settings within the code portion of an IoT solution and perform specific IoT coding tasks in at least one Azure-supported language, including C#, Node, C, or Python.
