You have an Azure IoT hub that uses a Device Provisioning Service instance to automate the deployment of Azure IoT Edge devices.The IoT Edge devices have a Trusted Platform Module (TPM) 2.0 chip.From the Azure portal, you plan to add an individual enrollment to the Device Provisioning Service that will use the TPM of the IoT Edge devices as the attestation mechanism.Which detail should you obtain before you can create the enrollment.

• the scope ID and the Device Provisioning Service endpoint
• the primary key of the Device Provisioning Service shared access policy and the global device endpoint
• the X.509 device certificate and the certificate chain
• the endorsement key and the registration ID

You need to visualize Azure IoT Hub telemetry data by using Microsoft Power BI.Which service should you connect to the IoT hub?

• Azure Event Grid
• SendGrid
• Azure Stream Analytics
• Azure Notification Hubs

You need to store the real-time alerts generated by Stream Analytics to meet the technical requirements.Which type of Stream Analytics output should you configure?

• Azure Blob storage
• Microsoft Power BI
• Azure Cosmos DB
• Azure SQL Database

You have an Azure IoT Edge device.You need to modify the credentials used to access the container registry. What should you modify?

• the @edgeHub module twin
• the IoT Edge module
• the $edgeAgent module twin
• the Azure IoT Hub device twin

You have an Azure IoT hub.You plan to implement IoT Hub events by using Azure Event Grid.You need to send an email when the following events occur:Device CreatedDevice DeletedDevice ConnectedDevice DisconnectedWhich two actions should you perform? Each correct answer presents part of the solution.NOTE: Each correct selection is worth one point.

• From the IoT hub, configure an event subscription that has API management as the Endpoint Type.
• From the IoT hub, configure an event subscription that has Web Hook as the Endpoint Type.
• Create an Azure logic app that has a Request trigger.
• From the IoT hub, configure an event subscription that has Service Bus Queue as the Endpoint Type.

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 a Standard tier Azure IoT hub and a fleet of IoT devices.The devices connect to the IoT hub by using either Message Queuing Telemetry Transport (MQTT) or Advanced Message Queuing Protocol (AMQP).You need to send data to the IoT devices and each device must respond. Each device will require three minutes to process the data and respond.Solution: You schedule an IoT Hub job to update the twin tags and you query for job progress.Does this meet the goal?

• yes
• No

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?

• device-id
• connection-device-id
• iothub-connection-device-id
• deviceId

You have an Azure loT solution that includes an Azure loT hub named Hub1.You plan to provision an loT device named Device! that will run Azure RTOS and the Azure loT middleware for Azure RTOS. Device1 will be deployed to a remote network that contains a firewall named FW1.You need to ensure that FW1 will allow Device1 to communicate with Hub1.Which port should you open on FW1?

• 5671
• 5683
• 8080
• 8883

You need to design a module deployment strategy that meets the device requirements. What should you create?
