You have 1,000 devices that connect to an Azure IoT hub.You are performing a scheduled check of deployed IoT devices.You plan to run the following command from the Azure CLI prompt. az iot hub query --hub-name hub1 --query-command "SELECT * FROM devices WHERE connectionState = 'Disconnected'"What does the command return?
You have an Azure IoT solution that includes several Azure IoT hubs.A new alerting feature was recently added to the IoT devices. The feature uses a new device twin reported property named alertCondition.You need to send alerts to an Azure Service Bus queue named MessageAlerts. The alerts must include alertCondition and the name of the IoT hub.Which two actions should you perform? Each correct answer presents part of the solution.NOTE: Each correct selection is worth one point.
DRAG DROP -You have 100 devices that connect to an Azure IoT hub.You need to be notified about failed local logins to a subset of the devices.Which three actions should you perform in sequence? To answer, move the appropriate actions from the list of actions to the answer area and arrange them in the correct order.Select and Place:
You have an Azure IoT solution that includes a basic tier Azure IoT hub named Hub1 and a Raspberry Pi device named Device1. Device1 connects to Hub1.You back up Device1 and restore the backup to a new Raspberry Pi device.When you start the new Raspberry Pi device, you receive the following error message in the diagnostic logs of Hub1: "409002 LinkCreationConflict."You need to ensure that Device1 and the new Raspberry Pi device can run simultaneously without error.Which two actions should you perform? Each correct answer presents part of the solution.NOTE: Each correct selection is worth one point.
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.
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, a Device Provisioning Service instance, and 1,000 connected IoT devices.All the IoT devices are provisioned automatically by using one enrollment group.You need to temporarily disable the IoT devices from the connecting to the IoT hub.Solution: From the Device Provisioning Service, you disable the enrollment group, and you disable device entries in the identity registry of the IoT hub to which theIoT devices are provisioned.Does the solution meet the goal?
