Question#1

You have an Azure subscription that contains an Azure loT hub named Hubl and an Azure loT Edge device named Devicel.
You need to configure Device1 to operate in extended offline mode and to support modifying the configuration of modules deployed to Device1 while the device is offline.
Solution: From Azure Cloud Shell, you run the following Azure CLI command.
ai lot edge set-nodules --device-id Device1 --hub-nane Hub1 --content deployment.json
Does this meet the goal?

A. Yes
B. No

Question#2

What should you do to identify the cause of the connectivity issues?

A. Send cloud-to-device messages to the IoT devices.
B. Use the heartbeat pattern to send messages from the IoT devices to iothub1.
C. Monitor the connection status of the device twin by using an Azure function.
D. Enable the collection of the Connections diagnostics logs and set up alerts for the connected devices count metric.

Explanation:
Scenario: You discover connectivity issues between the IoT gateway devices and iothub1, which cause IoT devices to lose connectivity and messages.
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.
Step 1:

Question#3

You have an Azure loT hub that has 500 registered devices.
You need to send device twin change events to Azure Service Bus in real time
Which blade of the loT hub should you configure?

A. Events
B. Metrics
C. Message routing
D. Diagnostic settings

Question#4

You plan to deploy an Azure IoT hub.
The IoT hub must support the following:
✑ Three Azure IoT Edge devices 2,500 IoT devices
✑ Each IoT device will spend a 6 KB message every five seconds.
You need to size the IoT hub to support the devices. The solution must minimize costs.
What should you choose?

A. one unit of the S1 tier
B. one unit of the B2 tier
C. one unit of the B1 tier
D. one unit of the S3 tier

Explanation:
2500* 6 KB * 12 = 180,000 KB/minute = 180 MB/Minute.
B3, S3 can handle up to 814 MB/minute per unit. Incorrect Answers:
A, C: B1, S1 can only handle up to 1111 KB/minute per unit B: B2, S2 can only handle up to 16 MB/minute per unit.

Question#5

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.

A. Build and push the SampleModule code to the registry.
B. Create a deployment for a single device.
C. Upload to Azure Storage.
D. Build an loT Edge solution.
E. Generate a shared access signature (SAS) token for Device 1.

Explanation:
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.
