You have an Azure subscription that contains an Azure IoT hub and two IoT devices named Device1 and Device2.
You plan to deploy an Azure IoT Edge gateway device named Gateway1.
You need to ensure that all device-to-cloud messages and twin change notifications from Device1 and Device2 to the IoT hub are routed by using Gateway1.
What tasks should you perform to configure the devices? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.

Box 1: Device1 and Device2
Connection strings for downstream devices need the following components:
* The gateway device that the device connects through. Provide the hostname value from the IoT Edge gateway device's config file: GatewayHostName={gateway hostname} Box 2: Gateway1 To deploy the IoT Edge hub module and configure it with routes to handle incoming messages from downstream devices, follow these steps:
* In the Azure portal, navigate to your IoT hub.
* Go to IoT Edge and select your IoT Edge device that you want to use as a gateway.
* Select Set Modules.
* On the Modules page, you can add any modules you want to deploy to the gateway device.
* Select Next: Routes.
* On the Routes page, make sure that there is a route to handle messages coming from downstream devices. For example:A route that sends all messages, whether from a module or from a downstream device, to IoT Hub:
Name: allMessagesToHub Value: FROM /messages/* INTO $upstream
Box 3: FROM /messages/* INTO $upstream

You are troubleshooting an Azure IoT hub.
You discover that some telemetry messages are dropped before they reach downstream processing. You suspect that IoT Hub throttling is the root cause.
Which log in the Diagnostics settings of the IoT hub should you use to capture the throttling error events?

• A.Routes
• B.DeviceTelemetry
• C.Connections
• D.C2DCommands

You have 20 devices that connect to an Azure IoT hub.
You open Azure Monitor as shown in the exhibit. (Click the Exhibit tab.)

You discover that telemetry is not being received from five IoT devices.
You need to identify the names of the devices that are not generating telemetry and visualize the dat a. What should you do first?

• A.Add the Number of throttling errors metric and archive the logs to an Azure storage account.
• B.Configure diagnostics for Routes and stream the logs to Azure Event Hubs.
• C.Add the Telemetry messages sent metric and archieve the logs to an Azure Storage account.
• D.Configure diagnostics for Connections and send the logs to Azure Log Analytics.

Correct Answer: D

To log device connection events and errors, turn on diagnostics for IoT Hub. We recommend turning on these logs as early as possible, because if diagnostic logs aren't enabled, when device disconnects occur, you won't have any information to troubleshoot the problem with.
Sign in to the Azure portal.
Browse to your IoT hub.
Select Diagnostics settings.
Select Turn on diagnostics.
Enable Connections logs to be collected.
For easier analysis, turn on Send to Log Analytics
