You need to analyze the real-time telemetry streams from the IoT devices in the Power BI dashboard. You create a new workspace. You also provision a Stream Analytics job under the name of “IoT stream job” in the Azure portal. 
Please select four steps you should take to give the “IoT stream job” access to the Power BI workspace?

Answer options:

A.Give a service principal access to the new workspace
B.Add a new job as the user in Microsoft 365 Admin Center
C.Allow service principals to use Power BI APIs in the Power BI Admin portal
D.Give a service principal access to My workspace
E.Create Power BI as new output for the job in the Azure portal
F.Create a service principal for the job in the Azure portal
G.Sign in to Power BI as a new user

Correct Answers: A, C, E and F 
Microsoft Managed Identity service for Azure eliminates the need to use passwords or other credentials explicitly to access Azure-based services. The Managed identity service manages credentials for you. You can use the Managed identities to access any Azure service. There are two types of managed identities: System assigned and User-assigned. The System assigned managed identity is a part of every Azure resource that stays with the resource. If the resource is removed, the identity is also removed. Users can create the User-assigned identity for any standalone Azure resource. It will survive resource after the resource deletion and can be assigned to another resource. You can remove the user-assigned identity only by deleting it directly. 
When you enable the System assigned identity for the Azure resource, Azure creates a service principal. The service principal is a resource that connects to the Azure AD managed identity information. The Power Platform products are based on Azure services, and you can use the service principal to access the Power BI. 
Suppose you need to stream data to the Power BI dashboard. In that case, you need to provision a Stream Analytics job in Azure and enable the “Use System-assigned Managed Identity” option (Number 2) in the “Managed Identity” section of the job’s blade (Number 1). The Azure Resource Manager generates the service principal ID (Number 3). 

Then you need to allow the service principal to use the Power BI APIs (Number 4). You can find this option in the Power BI admin portal (Number 1) in the “Tenant settings” (Number 2) under the “Developer settings” (Number 3). You can also limit the API access to the specific security group (Number 5). 

After that, you need to create a new workspace with a dashboard. You cannot use “My workspace.” Then, return to Azure and create an “IoT stream job” output by authorizing a connection to Power BI and supplying information about the Power BI workspace. 

And you need to enable the service principal access to the new Power BI workspace. You can click on the Access button on the workspace screen and add the job name. 
All other options are incorrect.
