新しい質問65
You have an Azure Stream Analytics job that connects to an Azure IoT hub named Hub1445 as a streaming data source. Hub1445 is configured as shown in the exhibit. (Click the Exhibit tab.)

The Stream Analytics job fails to receive any messages from the IoT hub. What should you do to resolve the issue?

Change the Route1 route query to true.

Enable the Route3 route.

Disable the Route2 route.

Enable the fallback route.

説明
The device telemetry is usually passed as JSON from the device through the IoT Hub – this is handled nicely by Azure Streaming Analytics queries.
The IoT Hub message routing should be configured as follows: Data source: Device Telemetry Messages Routing query: true (as the routing query is an expression that evaluates to true or false for each received message, the simplest way to send all messages to the endpoint is to just supply true as the query).

After you answer a question in this question, you will NOT be able to return to it. As a result, these questions will not appear in the review screen.
You have devices that connect to an Azure IoT hub. Each device has a fixed GPS location that includes latitude and longitude.
You discover that a device entry in the identity registry of the IoT hub is missing the GPS location.
You need to configure the GPS location for the device entry. The solution must prevent the changes from being propagated to the physical device.
Solution: You add the desired properties to the device twin. Does the solution meet the goal?

はい

いいえ

Device Twins are used to synchronize state between an IoT solution’s cloud service and its devices. Each device’s twin exposes a set of desired properties and reported properties. The cloud service populates the desired properties with values it wishes to send to the device. When a device connects it requests and/or subscribes for its desired properties and acts on them.

Existing Environment. Current State of Development
Contoso produces a set of Bluetooth sensors that read the temperature and humidity. The sensors connect to IoT gateway devices that relay the data.
All the IoT gateway devices connect to an Azure IoT hub named iothub1.
Existing Environment. Device Twin
You plan to implement device twins by using the following JSON sample.

Existing Environment. Azure Stream Analytics
Each room will have between three to five sensors that will generate readings that are sent to a single IoT gateway device. The IoT gateway device will forward all the readings to iothub1 at intervals of between 10 and 60 seconds.
You plan to use a gateway pattern so that each IoT gateway device will have its own IoT Hub device identity.
You draft the following query, which is missing the GROUP BY clause.
SELECT
AVG(temperature),
System.TimeStamp() AS AsaTime
FROM
Iothub
You plan to use a 30-second period to calculate the average temperature reading of the sensors.
You plan to minimize latency between the condition reported by the sensors and the corresponding alert issued by the Stream Analytics job.
Existing Environment. Device Messages
The IoT gateway devices will send messages that contain the following JSON data whenever the temperature exceeds a specified threshold.

The level property will be used to route the messages to an Azure Service Bus queue endpoint named criticalep.
Existing Environment. Issues
You discover connectivity issues between the IoT gateway devices and iothub1, which cause IoT devices to lose connectivity and messages.
Requirements. Planning Changes
Contoso plans to make the following changes:
* Use Stream Analytics to process and view data.
* Use Azure Time Series Insights to visualize data.
* Implement a system to sync device statuses and required settings.
* Add extra information to messages by using message enrichment.
* Create a notification system to send an alert if a condition exceeds a specified threshold.
* Implement a system to identify what causes the intermittent connection issues and lost messages.
Requirements. Technical Requirements
Contoso must meet the following requirements:
* Use the built-in functions of IoT Hub whenever possible.
* Minimize hardware and software costs whenever possible.
* Minimize administrative effort to provision devices at scale.
* Implement a system to trace message flow to and from iothub1.
* Minimize the amount of custom coding required to implement the planned changes.
* Prevent read operations from being negatively affected when you implement additional services.

You have an Azure IoT Central application that includes a Device Provisioning Service instance.
You need to connect IoT devices to the application without first registering the devices.
In which order should you perform the actions? To answer, move all actions from the list of actions to the answer area and arrange them in the correct order.

説明する：
Step: With DPS (Device Provisioning Service) you can generate device credentials and configure the devices offline without registering the devices through IoT Central UI.
Connect devices that use SAS tokens without registering
1. Copy the IoT Central application’s group primary key
2. Use the dps-keygen tool to generate the device SAS keys. Use the group primary key from the previous step. The device IDs must be lower-case:
dps-keygen -mk:<group primary key> -di:<device ID>
3. The OEM flashes each device with a device ID, a generated device SAS key, and the application ID scope value.
4. When you switch on a device, it first connects to DPS to retrieve its IoT Central registration information.
The device initially has a device status Unassociated on the Devices page and isn’t assigned to a device template. On the Devices page, Migrate the device to the appropriate device template. Device provisioning is now complete, the device status is now Provisioned, and the device can start sending data.
On the Administration > Device connection page, the Auto approve option controls whether you need to manually approve the device before it can start sending data.

You need to install the Azure IoT Edge runtime on a new device that runs Windows 10 IoT Enterprise.
順番に実行すべき4つのアクションはどれでしょう？答えるには、アクションのリストから適切なアクションを解答エリアに移動し、正しい順番に並べます。

説明

説明する：
Step 1: From Azure IoT Hub, create an IoT Edge Device
Step 2: Deploy-IoTEdge
The Deploy-IoTEdge command checks that your Windows machine is on a supported version, turns on the containers feature, and then downloads the moby runtime and the IoT Edge runtime. The command defaults to using Windows containers.
{Invoke-WebRequest -useb https://aka.ms/iotedge-win} | Invoke-Expression; ` Deploy-IoTEdge Step 3: Initialize-IoTEdge The Initialize-IoTEdge command configures the IoT Edge runtime on your machine. The command defaults to manual provisioning with Windows containers.
{Invoke-WebRequest -useb https://aka.ms/iotedge
Step 4: Enter the IoT Edge device connection string.
When prompted, provide the device connection string that you retrieved in step 1. The device connection string associates the physical device with a device ID in IoT Hub.

You have an Azure subscription that contains an Azure IoT hub and two Azure IoT Edge devices named Device1 and Device2.
You need to ensure that the IoT hub only accepts connections from Device1 and Device2.
What should you configure?

a private endpoint connection

Azure API Management

Azure Active Directory (Azure AD) Identity Protection

a gateway device

Ingress connectivity to IoT Hub using Azure Private Link.
A private endpoint is a private IP address allocated inside a customer-owned VNet via which an Azure resource is reachable. Through Azure Private Link, you can set up a private endpoint for your IoT hub to allow services inside your VNet to reach IoT Hub without requiring traffic to be sent to IoT Hub’s public endpoint. Similarly, your on-premises devices can use Virtual Private Network (VPN) or ExpressRoute peering to gain connectivity to your VNet and your IoT Hub (via its private endpoint). As a result, you can restrict or completely block off connectivity to your IoT hub’s public endpoints by using IoT Hub IP filter or the public network access toggle. This approach keeps connectivity to your Hub using the private endpoint for devices.
