At ValidExamDumps, we consistently monitor updates to the Microsoft AZ-220 exam questions by Microsoft. Whenever our team identifies changes in the exam questions,exam objectives, exam focus areas or in exam requirements, We immediately update our exam questions for both PDF and online practice exams. This commitment ensures our customers always have access to the most current and accurate questions. By preparing with these actual questions, our customers can successfully pass the Microsoft Azure IoT Developer exam on their first attempt without needing additional materials or study guides.
Other certification materials providers often include outdated or removed questions by Microsoft in their Microsoft AZ-220 exam. These outdated questions lead to customers failing their Microsoft Azure IoT Developer exam. In contrast, we ensure our questions bank includes only precise and up-to-date questions, guaranteeing their presence in your actual exam. Our main priority is your success in the Microsoft AZ-220 exam, not profiting from selling obsolete exam questions in PDF or Online Practice Test.
You have an Azure IoT solution that includes an Azure IoT hub and 100 Azure IoT Edge devices.
You plan to deploy the IoT Edge devices to external networks. The firewalls of the external networks only allow traffic on port 80 and port 443.
You need to ensure that the devices can connect to the IoT hub. The solution must minimize costs. What should you do?
MQTT over WebSockets uses port 443.

You have an Azure loT Central solution
You need to verify that telemetry messages from devices arrive to loT Central.
What should you use?
You have 1,000 devices that connect to an Azure IoT hub.
You discover that some of the devices fail to send data to the IoT hub.
You need to ensure that you can use Azure Monitor to troubleshoot the device connectivity issues.
Which two actions should you perform? Each correct answer presents part of the solution.
NOTE: Each correct selection is worth one point.
The IoT Hub resource logs connections category emits operations and errors having to do with device connections. The following screenshot shows a diagnostic setting to route these logs to a Log Analytics workspace:
Note: Azure Monitor: Route connection events to logs:
IoT hub continuously emits resource logs for several categories of operations. To collect this log data, though, you need to create a diagnostic setting to route it to a destination where it can be analyzed or archived. One such destination is Azure Monitor Logs via a Log Analytics workspace, where you can analyze the data using Kusto queries.

You are building an Azure loT solution that will include an Azure loT hub and will process environmental data for a multi-story building by using Azure Stream Analytics. The loT devices for the solution will provide the following data:
* Temperature
* Building
* Room
* Floor
You need to identify which data formats the loT devices can use to send the data as an array. What should you identify?
You need to recommend a solution to keep device properties synced to IoT Hub. The solution must minimize data loss caused by the connectivity issues.
What should you include in the recommendation?
Scenario: You discover connectivity issues between the IoT gateway devices and iothub1, which cause IoT devices to lose connectivity and messages.
To synchronize state information between a device and an IoT hub, you use device twins. A device twin is a JSON document, associated with a specific device, and stored by IoT Hub in the cloud where you can query them. A device twin contains desired properties, reported properties, and tags.

This is a case study. Case studies are not timed separately. You can use as much exam time as you would like to complete each case. However, there may be additional case studies and sections on this exam. You must manage your time to ensure that you are able to complete all questions included on this exam in the time provided.
To answer the questions included in a case study, you will need to reference information that is provided in the case study. Case studies might contain exhibits and other resources that provide more information about the scenario that is described in the case study. Each question is independent of the other question on this case study.
At the end of this case study, a review screen will appear. This screen allows you to review your answers and to make changes before you move to the next sections of the exam. After you begin a new section, you cannot return to this section.
