Explaining Associated Certification

Making efforts towards AZ-220 exam leads to earning the Microsoft Certified: Azure IoT Developer Specialty certification. It is an upper-level designation designed to impart in candidates best-in-class expertise in cloud development and edge components of an Azure IoT solution. The earners of this high-skilled certificate are also known to have unmatched expertise in device life cycle set-up, the configuration of cloud services, debugging the IoT issues, and the transformation of IoT-related data pipelines.

Exam Syllabus

This Microsoft exam measures specific technical skills. Therefore, you must develop competence in these technical areas to be able to achieve success in the certification test. The domains covered in the exam are highlighted below:

• Implementation of IoT Solution Infrastructures: 15-20%

  This topic shows that you are able to create and configure IoT Hub. Besides that, you must also demonstrate competence in registering a device, configuring a device twin, and IoT Hub tier & scaling. It also helps the candidates develop their skills in building communication and device messaging as well as configuring substantial IoT devices.

• Security Implementation: 15-20%

  This objective requires that the individuals demonstrate their expertise in the implementation of device authentication within IoT Hub, implementation of device security with the use of DPS, as well as implementation of Azure Defender for IoT.

• Implementation of Edges: 15-20%

  The potential candidates for the Microsoft AZ-220 exam should possess the capability to deploy IoT Edge devices, set up them, and develop modules. They will be required to demonstrate their skills in creating device identity with IoT Hub, deploying production certificates, securing Internet of Things Edge solutions, and provisioning IoT Edge devices with the use of DPS. The questions from this section will also measure their skills in configuring IoT Edge devices, including selecting and deploying the relevant gateway pattern, implementing module-to-module communications, and configuring offline support.

• Monitoring, Optimization, and Troubleshooting of Internet of Things Solutions: 15-20%

  The questions from this area will measure the skills of the test takers in the configuration of health monitoring, troubleshooting of specific device communications, and execution of end-to-end solution diagnostics and testing.

• Data Processing & Management: 15-20%

  This part focuses on the examinees’ skills in configuring routing within Azure Internet of Things Hub. It also covers their ability to configure stream processing, and configure the IoT solution for TSI. The applicants should know how to create stream processing for IoT data and ASA for data. They should also be able to implement solutions for handling time-stamped and telemetry data.

• Provisioning & Management of Devices: 20-25%

  In the framework of this subject area, one’s skills in implementing DPS, managing device lifecycle, and using IoT devices with the help of IoT Hub will be evaluated. The learners need to possess the expertise required to develop a solution with the use of IoT Central. This covers the skills in defining an operator’s view, monitoring devices, and monitoring an application’s health with metrics. You should also have some expertise in configuring actions and rules in Azure IoT Central and defining device types in it.
