You need to visualize Azure IoT Hub telemetry data by using Microsoft Power BI.
Which service should you connect to the IoT hub?
You can use Microsoft Power BI to visualize real-time sensor data that your Azure IoT hub receives. To do so, you configure an Azure Stream Analytics job to consume the data from IoT Hub and route it to a dataset in Power BI.
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?
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.
You have an Azure IoT solution that contains an Azure IoT hub and 100 IoT devices. The devices run Windows Server 2016.
You need to deploy the Azure Defender for IoT C#-based security agent to the devices.
What should you do first?
The IoT Edge security manager provides a safe framework for security service extensions through host-level modules. The IoT Edge security manager include
Ensure safe operation of client agents for services including Device Update for IoT Hub and Azure Defender for IoT.
You deploy an Azure Digital Twins instance.
You are developing client code that will modify digital twin data.
You run the client code and receive the following response for an Azure Digital Twins API.
You need to configure access control for the Azure Digital Twins instance to ensure that the client code can modify the data.
Which role should you assign?
Most often, this error indicates that your Azure role-based access control (Azure RBAC) permissions for the service aren't set up correctly. Many actions for an Azure Digital Twins instance require you to have the Azure Digital Twins Data Owner role on the instance you are trying to manage.
You have an Azure IoT solution.
You need to create a digital twin model.
Which language should you use?
Azure Digital Twins models are represented in the JSON-LD-based Digital Twin Definition Language (DTDL).
