Welcome to Day 24 of #JulyOT!!
This is part 2 of a series of posts to help you pass the AZ-220 Azure IoT Developer specialty exam. 15-20% of the AZ-220 exam will measure your ability to provision and manage devices.
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: Provision and Manage Devices
Set up the device provisioning service
- Create a device provisioning service
- Create a new enrollment in the device provisioning service
- Link an IoT hub to the device provisioning service
Manage the device lifecycle
- Provision a device by using the device provisioning service
- Deprovision an auto-enrollment
- Decommission (disenroll) a device
Manage IoT devices by using IoT Hub
- Manage devices list in the IoT Hub device registry
- Modify device twin tags and properties
- Specify a set of devices to manage by using IoT Hub Automatic Device Management
- Implement and manage configuration on a set of devices by using IoT Hub Automatic Device Management
- Control access to device functionality by using module identities and module twins
Manage IoT devices by using Azure IoT Central
- Create and manage device templates by using Azure IoT Central and Digital Twins Definition Language (DTDL)
- Configure rules, actions, and commands in Azure IoT Central
- Add, enroll, and manage devices by using Azure IoT Central
- Manage Azure IoT Central applications, including security, tenants, customization, and visualizations
- Manage data integration, including data ingress, data export, and data transformation
- Configure and manage Azure IoT Central jobs
- Manage Azure IoT Central by using APIs
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).
