Exam PL-300 topic 1 question 34 discussion

I think it is B because this link - has this point - Select Get Data > Online Services, Azure DevOps (Boards only) for cloud services or select Azure DevOps Server (Boards only) for on-premises. Then select Connect. Analytics views only support queries against work items and test cases. I am assuming this is about DevOps on the cloud

Use Analytics Views: Analytics views in Azure DevOps are exposed via OData, which allows querying data from the cloud using structured formats. The OData Feed connector in Power BI is designed to connect to OData endpoints, such as Azure DevOps Analytics views. Filter Data from the Cloud: The OData Feed connector allows you to apply filters and queries to fetch only the required data from Azure DevOps in the cloud.

To meet the requirements of using Analytics views and filtering data from the cloud, you should use the **Azure DevOps (Boards only)** connector. This connector is specifically designed to work with Analytics views in Azure DevOps and supports cloud-based data filtering (https://learn.microsoft.com/en-us/azure/devops/report/powerbi/data-connector-connect?view=azure-devops).

A over D because it is odata querie is more streamilned and efficent

D. OData Feed Azure DevOps Analytics views expose data through OData feeds. Using the OData Feed connector allows Power BI to pull data from Azure DevOps Analytics while leveraging its built-in filtering capabilities. Why not the other options? A. OData Queries: While this is a generic term, Power BI uses the "OData Feed" connector to interact with OData sources. B. Azure DevOps (Boards only): This connector is designed specifically for Azure Boards data but doesn't support Analytics views or advanced filtering. C. Azure DevOps Server (Boards only): This connector is for on-premises Azure DevOps Server and not the cloud version.

While B seem to be the correct option, the question says you need to authenticate for the Azure service. That step is done in Odata feed. Option B has analytics view but you do not authenticate for the Azure service (the step doesnt exist). Ref: https://learn.microsoft.com/en-us/azure/devops/report/powerbi/data-connector-connect?view=azure-devops. Therefore the answer should be D.

To authenticate to Azure DevOps, use the OData queries connector in Power BI Desktop, as it supports accessing and filtering Analytics views from the cloud.

B - See https://learn.microsoft.com/en-us/azure/devops/report/powerbi/create-quick-report?view=azure-devops

OData Feed is the connector designed for retrieving data from OData services, which Azure DevOps provides for Analytics views

A. OData queries: This is a method for querying OData but not the actual connector you need to use in Power BI. B. Azure DevOps (Boards only): This connector is specifically for Boards (work items) and does not support Analytics views or advanced filtering. C. Azure DevOps Server (Boards only): This is for on-premises Azure DevOps Server, not the cloud version, which you are using. So the answer is D

The correct answer is: D. OData Feed Why Not the Other Options?: A. OData Queries: While related, this is not a specific connector option in Power BI Desktop. B. Azure DevOps (Boards only): This connector is limited to Azure Boards and does not integrate with Analytics Views. C. Azure DevOps Server (Boards only): This is for on-premises Azure DevOps Server, not Azure DevOps Services (cloud).

OData Feed allows you to connect directly to Azure DevOps Analytics views, which are accessible via the OData protocol. Analytics Views in Azure DevOps are specifically designed to simplify querying and visualizing data from Azure DevOps services, and OData Feed is the connector that supports accessing these views. Filtering data from the cloud is supported by OData feeds, as you can apply filters within the OData query before importing the data into Power BI.

I think D, https://learn.microsoft.com/en-us/azure/devops/report/powerbi/overview?view=azure-devops

In the link shared by f3ecb98 below, I understand to connect to Azure DevOps data an OData connector is needed. I've checked in Power BI Desktop available "OData connector" is presented as "ODat Feed" (once connected, an OData code must be written to set the OData queries retrieving data, but these are not connectors) so I would vote for Answer D

A. OData queries: While this refers to querying OData, Power BI does not have a specific connector called "OData queries." Instead, it uses the OData Feed connector. B. Azure DevOps (Boards only): This connector is used for Board-related data but does not support Analytics views or OData.
