You have a deployment pipeline for a Power BI workspace. The workspace contains two datasets that use import storage mode.

A database administrator reports a drastic increase in the number of queries sent from the Power BI service to an Azure SQL database since the creation of the deployment pipeline.

An investigation into the issue identifies the following:

One of the datasets is larger than 1 GB and has a fact table that contains more than 500 million rows. When publishing dataset changes to development, test, or production pipelines, a refresh is triggered against the entire dataset.

You need to recommend a solution to reduce the size of the queries sent to the database when the dataset changes are published to development, test, or production.

What should you recommend?

A. From Capacity settings in the Power Bl Admin portal, reduce the Max Intermediate Row Set Count setting.

B. Configure the dataset to use a composite model that has a DirectQuery connection to the fact table.

C. Enable the large dataset storage format for workspace.

D. From Capacity settings in the Power Bl Admin portal, increase the Max Intermediate Row Set Count setting.

You use an Apache Spark notebook in Azure Synapse Analytics to filter and transform data.

You need to review statistics for a DataFrame that includes:

The column name The column type The number of distinct values Whether the column has missing values

Which function should you use?

A. displayHTML()

B. display(df, summary=true)

C. %%configure

D. display(df)

E. %%lsmagic

You have a Power BI Premium capacity.

From the Power BI Premium Capacity Metrics app, you discover the following:

There is insufficient CPU to execute dataset refreshes.

You need to recommend a solution to resolve the performance issues.

Solution: You move the datasets to a larger capacity.

Does this meet the goal?

A. Yes

B. No

You have a Power BI tenant and an Azure subscription named Sub1. The Power BI 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 BI 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.

A. Reader

B. Storage Blob Data Contributor

C. Contributor

D. Owner

E. Storage Blob Data Owner
