This is part 1 of a series of posts to help you pass the AZ-220 Azure IoT Developer specialty exam. 10-15% of the AZ-220 exam will measure your ability to setup the IoT solution infrastructure.
The Microsoft Global Partner Solutions (GPS) Technical Team, IoT Product Group, IoT Advocates, and Microsoft Worldwide Learning have collaborated to create this guide to help you prepare for the Microsoft Azure IoT Developer exam!
Skills Measured: Setup the Azure IoT Solution Infrastructure
Create and configure an IoT hub
Build device messaging and communication
- Build messaging solutions by using SDKs (device and service)
- Implement device-to-cloud communication
- Implement cloud-to-device communication
- Configure file upload for devices
- Optimize message size and scaling for IoT Hub
- Connect to IoT Hub by using Transport Layer Security (TLS) server certificates
Configure physical IoT devices
- Recommend an appropriate protocol or gateway based on device specifications
- Configure device networking, topology, and connectivity
- Add IoT Plug and Play capabilities to a device in a model-driven solution
NOTE: In most cases, exams do NOT cover preview features, and some features will only be added to an exam when they are GA (General Availability).
