質問 68
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. From Capacity settings in the Power Bl Admin portal, increase the Max Intermediate Row Set Count setting.
- C. Enable the large dataset storage format for workspace.
- D. Configure the dataset to use a composite model that has a DirectQuery connection to the fact table.
正解: D
解説:
A composite model in Power BI means part of your model can be a DirectQuery connection to a data source (for example, SQL Server database), and another part as Import Data (for example, an Excel file). Previously, when you used DirectQuery, you couldn't even add another data source into the model.
DirectQuery and Import Data have different advantages.
Now the Composite Model combines the good things of both Import and DirectQuery into one model. Using the Composite Model, you can work with big data tables using DirectQuery, and still import smaller tables using Import Data.

質問 69
You develop a solution that uses a Power Bl Premium capacity. The capacity contains a dataset that is expected to consume 50 GB of memory.
Which two actions should you perform to ensure that you can publish the model successfully to the Power Bl service? Each correct answer presents part of the solution.
NOTE: Each correct selection is worth one point.
- A. Restart the capacity.
- B. Publish an initial dataset that is less than 10 GB.
- C. Invoke a refresh to load historical data based on the incremental refresh policy.
- D. Publish the complete dataset.
- E. Increase the Max Offline Dataset Size setting.
正解: C,D
解説:
Enable large datasets
Steps here describe enabling large datasets for a new model published to the service. For existing datasets, only step 3 is necessary.
Create a model in Power BI Desktop. If your dataset will become larger and progressively consume more memory, be sure to configure Incremental refresh.
Publish the model as a dataset to the service.
In the service > dataset > Settings, expand Large dataset storage format, set the slider to On, and then select Apply.
Enable large dataset slider
Invoke a refresh to load historical data based on the incremental refresh policy. The first refresh could take a while to load the history. Subsequent refreshes should be faster, depending on your incremental refresh policy.

You are optimizing a dataflow in a Power Bl Premium capacity. The dataflow performs multiple joins. You need to reduce the load time of the dataflow.
Which two actions should you perform? Each correct answer presents part of the solution. NOTE: Each correct selection is worth one point.
- A. Place the ingestion operations and transformation operations in a single dataflow.
- B. Execute non-foldable operations before foldable operations.
- C. Reduce the memory assigned to the dataflows.
- D. Place the ingestion operations and transformation operations in separate dataflows.
- E. Execute foldable operations before non-foldable operations.
正解: D,E
解説:
Using the compute engine to improve performance
Take the following steps to enable workloads trigger the compute engine, and always improve performance:
For computed and linked entities in the same workspace:
Ensure you perform the operations that fold, such as merges, joins, conversion, and others.
For ingestion focus on getting the data into the storage as fast as possible, using filters only if they reduce the overall dataset size. It's best practice to keep your transformation logic separate from this step, and allow the engine to focus on the initial gathering of ingredients. Next, separate your transformation and business logic into a separate dataflow in the same workspace, using linked or computed entities; doing so allows for the engine to activate and accelerate your computations. In our analogy, it's like food preparation in the kitchen: food preparation is typically a separate and distinct step from gathering your raw ingredients, and a pre-requisite for putting the food in the oven. Similarly, your logic needs to be prepared separately before it can take advantage of the compute engine.

NOTE: Each correct selection is worth one point.
- A. Change the report theme to monochromatic.
- B. Replace all the filters on the Filters pane with visual slicers on the report page.
- C. Replace the product category charts with a bar chart for sales and a hierarchy of Category and Sub Category on the axis.
- D. Replace the single-value cards with a multi-row card.
