Microsoft DP-500 Designing and Implementing Enterprise-Scale Analytics Solutions Using Microsoft Azure and Microsoft Power BI Exam Practice Test

You have a Power Bl tenant and an Azure subscription named Sub1. The Power Bl tenant and Sub1 are linked to a single Azure AD tenant.

In Sub1, you create a storage account named storage1.

You need to configure a Power Bl workspace to store dataflows in storage1. The solution must use the principle of least privilege.

Which three roles should you assign for storage1? Each correct answer presents part of the solution.

NOTE: Each correct selection is worth one point.

Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution that might meet the stated goals. Some question sets might have more than one correct solution, while others might not have a correct solution.

After you answer a question in this section, you will NOT be able to return to it. As a result, these questions will not appear in the review screen.

From Power Query Editor, you profile the data s

the following exhibit

The loT GUID and loT ID columns are unique to each row in the query.

You need to analyze loT events by the hour and day of the year. The solution must improve dataset performance.

Solution: You change the loT DateTime column to the date data type.

Does this meet the goal?

You have a Power Bl report that contains a bar chart. The bar chart displays sales by country.

You are using an Azure Synapse Analytics serverless SQL pool to query a collection of Apache Parquet files by using automatic schema inference. The files contain more than 40 million rows of UTF-8-encoded business names, survey names, and participant counts. The database is configured to use the default collation.

The queries use open row set and infer the schema shown in the following table.

You need to recommend changes to the queries to reduce I/O reads and tempdb usage.

Solution: You recommend defining an external table for the Parquet files and updating the query to use the table

Does this meet the goal?

You have a group of data scientists who must create machine learning models and run periodic experiments on a large dataset.

You need to recommend an Azure Synapse Analytics pool for the data scientists. The solution must minimize costs.

Which type of pool should you recommend?
