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: You delete the enrollment group from the Device Provisioning Service. Does the solution meet the goal?

• A.Yes
• B.No

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.

• A.From the Diagnostics settings of the IoT hub, select Archive to a storage account.
• B.Collect the DeviceTelemetry, Connections, and Routes logs.
• C.Collect all metrics.
• D.From the Diagnostics settings of the IoT hub, select Send to Log Analytic.
• E.Collect the JobsOperations, DeviceStreams, and FileUploadOperations logs.

Correct Answer: B,D

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.
