NEW QUESTION 62
You have a 2-GB Power Bl dataset.
You need to ensure that you can redeploy the dataset by using Tabular Editor. The solution must minimize how long it will take to apply changes to the dataset from powerbi.com.
Which two actions should you perform in powerbi.com? Each correct answer presents part of the solution.
NOTE: Each correct selection is worth one point
- A. Enable XMLA read-write.
- B. Connect the target workspace to an Azure Data Lake Storage Gen2 account.
- C. Turn on Large dataset storage format.
- D. Enable service principal authentication for read-only admin APIs.
Answer: A,C
Explanation:
Optimize datasets for write operations by enabling large models
When using the XMLA endpoint for dataset management with write operations, it's recommended you enable the dataset for large models. This reduces the overhead of write operations, which can make them considerably faster. For datasets over 1 GB in size (after compression), the difference can be significant.
Tabular Editor supports Azure Analysis Services and Power BI Premium Datasets through XMLA read/write.
Note: Tabular Editor - An open-source tool for creating, maintaining, and managing tabular models using an intuitive, lightweight editor. A hierarchical view shows all objects in your tabular model. Objects are organized by display folders with support for multi-select property editing and DAX syntax highlighting. XMLA read-only is required for query operations. Read-write is required for metadata operations.

NEW QUESTION 63
You have a Power Bl data model.
You need to refresh the data from the source every 15 minutes.
What should you do first?
- A. Enable the XMLA endpoint.
- B. Change the storage mode of the dataset.
- C. Define an incremental refresh policy.
- D. Configure a scheduled refresh.

NEW QUESTION 64
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.
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 a data source and view for the Parquet files. You recommend updating the query to use the view.
Does this meet the goal?
- A. Yes
- B. No
Answer: B
Explanation:
Solution: You recommend using OPENROWSET WITH to explicitly specify the maximum length for businessName and surveyName.
The size of the varchar(8000) columns are too big. Better reduce their size.
A SELECT...FROM OPENROWSET(BULK...) statement queries the data in a file directly, without importing the data into a table. SELECT...FROM OPENROWSET(BULK...) statements can also list bulk-column aliases by using a format file to specify column names, and also data types.
NEW QUESTION 65

- A. Replace long text with abbreviations and acronyms.
- B. Configure a distinct color for each series.
- C. Configure a unique marker for each series.
- D. Move important information to a tooltip.
Answer: B
Explanation:

Certain color combinations are particularly difficult for users with color vision deficiencies to distinguish. These include the following combinations:
green and red
green and brown
blue and purple
green and blue
light green and yellow
blue and grey
green and grey
green and black
Avoid using these colors together in a chart, or on the same report page.

You need to recommend a solution to reduce the load times of the reports.
Solution: You recommend denormalizing the data model.
Does this meet the goal?
- A. Yes
- B. No

Topic 2, Contoso, Ltd
Overview
Contoso, Ltd. is a company that sells enriched financial data to a variety of external customers.
Contoso has a main office in Los Angeles and two branch offices in New York and Seattle.
Data Infrastructure
Contoso has a 50-TB data warehouse that uses an instance of SQL Server on Azure Virtual Machines.
The data warehouse populates an Azure Synapse Analytics workspace that is accessed by the external
customers. Currently, the customers can access alt the data.
Contoso has one Power Bl workspace named FinData that contains a single dataset. The dataset contains
financial data from around the world. The workspace is used by 10 internal users and one external customer.
The dataset has the following two data sources: the data warehouse and the Synapse Analytics serverless SQL
pool.
Users frequently query the Synapse Analytics workspace by using Transact-SQL.
User Problems
Contoso identifies the following user issues:
* Some users indicate that the visuals in Power Bl reports are slow to render when making filter selections.
* Users indicate that queries against the serverless SQL pool fail occasionally because the size of tempdb has
been exceeded.
* Users indicate that the data in Power Bl reports is stale. You discover that the refresh process of the Power Bl
model occasionally times out
Planned Changes
Contoso plans to implement the following changes:
* Into the existing Power Bl dataset, integrate an external data source that is accessible by using the REST
API.
* Build a new dataset in the FinData workspace by using data from the Synapse Analytics dedicated SQL pool.
* Provide all the customers with their own Power Bl workspace to create their own reports. Each workspace
will use the new dataset in the FinData workspace.
* Implement subscription levels for the customers. Each subscription level will provide access to specific rows
of financial data.
* Deploy prebuilt datasets to Power Bl to simplify the query experience of the customers.
* Provide internal users with the ability to incorporate machine learning models loaded to the dedicated SQL
pool.
NEW QUESTION 74
You have a Power Bi workspace named Workspacel in a Premium capacity. Workspacel contains a dataset.
During a scheduled refresh, you receive the following error message: "Unable to save the changes since the
new dataset size of 11,354 MB exceeds the limit of 10,240 MB."
You need to ensure that you can refresh the dataset.
What should you do?
- A. Change License mode to Premium per user.
- B. Change the location of the Premium capacity.
- C. Turn on Large dataset storage format.
- D. Connect Workspace1 to an Azure Data Lake Storage Gen2 account
Answer: C
NEW QUESTION 75
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. Increase the Max Offline Dataset Size setting.
- B. Invoke a refresh to load historical data based on the incremental refresh policy.
- C. Publish an initial dataset that is less than 10 GB.
- D. Restart the capacity.
- E. Publish the complete dataset.
Answer: B,E
Explanation:
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.
NEW QUESTION 76
You have a Power Bl dataset that contains the following measures:
* Budget
* Actuals
* Forecast
You create a report that contains 10 visuals.
You need provide users with the ability to use a slicer to switch between the measures in two visuals only.
You create a dedicated measure named cg Measure switch.
How should you complete the DAX expression for the Actuals measure? To answer, drag the appropriate values to the targets. Each value may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.
