You have IoT devices that connect to an Azure IoT hub.
From IoT Hub, you create an Event subscription to be notified when devices are registered to IoT Hub. You select webhook endpoint as a handler for the Event subscription.
Which two types of Event Grid messages will be received by the webhook? Each correct answer presents a complete solution.
NOTE: Each correct selection is worth one point.
See the explanation below.
Microsoft.Devices.DeviceCreated: Published when a device is registered to an IoT hub.
The first thing you want to do is handle Microsoft.EventGrid.SubscriptionValidationEvent events. Every time someone subscribes to an event, Event Grid sends a validation event to the endpoint with a validationCode in the data payload.

You have an Azure IoT solution that includes an Azure IoT hub named hub1.
You plan to deploy an Azure Time Series Insights Gen 2 environment and connect the environment to hub1.
You need to use the device ID from hub1 as the Time Series ID.
What should you set as the Time Series ID when creating the environment?
See the explanation below.
Your Time Series ID property is iothub-connection-device-id, dt-subject.
As an IoT Plug and Play user, for your Time Series ID, specify a composite key that consists of iothub-connection-device-id and dt-subject. The IoT hub adds these system properties that contain your IoT Plug and Play device ID and your device component names, respectively.

You have an Azure IoT Edge module named SampleModule that runs on a device named Device1.
You make changes to the code of SampleModule by using Microsoft Visual Studio Code.
You need to push the code to the container registry and then deploy the module to Device1.
Which two actions should you perform from Visual Studio Code? Each correct answer presents part of the solution.
NOTE: Each correct selection is worth one point.
See the explanation below.
D: Once you create IoT Edge modules with your business logic, you want to deploy them to your devices to operate at the edge.
B: Configure a deployment manifest. A deployment manifest is a JSON document that describes which modules to deploy, how data flows between the modules, and desired properties of the module twins.
You deploy modules to your device by applying the deployment manifest that you configured with the module information.
In the Visual Studio Code explorer view, expand the Azure IoT Hub section, and then expand the Devices node.
To confirm that the device you've chosen is an IoT Edge device, select it to expand the list of modules and verify the presence of $edgeHub and $edgeAgent. Every IoT Edge device includes these two modules.
Select Create Deployment for Single Device.
Navigate to the deployment manifest JSON file that you want to use, and click Select Edge Deployment Manifest.

Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution that might meet the stated goals. Some question sets might have more than one correct solution, while others might not have a correct solution.
After you answer a question in this section, you will NOT be able to return to it. As a result, these questions will not appear in the review screen.
You have an Azure IoT solution that includes an Azure IoT hub and an Azure IoT Edge device.
You plan to deploy 10 Bluetooth sensors. The sensors do not support MQTT, AMQP, or HTTPS.
You need to ensure that all the sensors appear in the IoT hub as a single device.
Solution: You configure the IoT Edge device as an IoT Edge identity translation gateway. You configure the sensors to connect to the device.
Does this meet the goal?
See the explanation below.
In the protocol translation gateway pattern, only the IoT Edge gateway has an identity with IoT Hub. The translation module receives messages from downstream devices, translates them into a supported protocol, and then the IoT Edge device sends the messages on behalf of the downstream devices. All information looks like it is coming from one device, the gateway.

You plan to develop modules for an Azure IoT Edge solution.
You need to recommend a development tool that supports the following:
Node.js
Module templates
Development on Linux workstations
What should you recommend?
See the explanation below.
Use Visual Studio Code to develop Node.js code and deploy it to a device running Azure IoT Edge.
You can use IoT Edge modules with Linux containers to deploy code that implements your business logic directly to your IoT Edge devices.
