Updates to the exam
Our exams are updated periodically to reflect skills that are required to perform a role. We have included two versions of the Skills Measured objectives depending on when you are taking the exam.
We always update the English language version of the exam first. Some exams are localized into other languages, and those are updated approximately eight weeks after the English version is updated. Other available languages are listed in the Schedule Exam section of the Exam Details webpage. If the exam isn't available in your preferred language, you can request an additional 30 minutes to complete the exam.
Note
The bullets that follow each of the skills measured are intended to illustrate how we are assessing that skill. Related topics may be covered in the exam.
Note
Most questions cover features that are general availability (GA). The exam may contain questions on Preview features if those features are commonly used.
Skills measured as of January 30, 2023
Audience profile
Candidates for this exam are Azure IoT developers with subject matter expertise in creating and maintaining the cloud and device portions of an IoT solution. In addition to configuring and maintaining the devices by using cloud services, they also set up the physical devices. They are responsible for maintaining and troubleshooting the configuration of the devices throughout the lifecycle.
Azure IoT developers implement design specifications for IoT solutions, including device topology, connectivity, diagnostics and monitoring, and security. They develop the code that enables two-way communication between the device and the cloud. They also develop and deploy modules and configure device networking for the Azure IoT Edge portion of the solution. Professionals in this role implement designs for solutions to manage data streams, including monitoring and data transformation as they relate to IoT. The Azure IoT developer works with architects, device developers, data engineers, and other stakeholders to help ensure successful business integration.
Candidates for this exam should have a general understanding of device types and Azure services, including data storage options, data analysis, data processing, AI, and other platform as a service (PaaS) options. They must be able to program in at least one Azure IoT software development kit–supported (SDK-supported) language.
