Select only one answer. In Power BI Desktop, create a role. In Power BI Desktop, define filter parameters. Deploy the report to the Power BI service. Upgrade the Power BI workspace to the Premium SKU.
In Power BI Desktop, create a role. To use row-level security to ensure that, once the report is published, employees in each department can only see the sales data for that department, you first need to create a role and a corresponding DAX expression. Filter parameters are used for other purposes, such as incremental refresh policy, not row-level security. Deploying the report to the Power BI service is required for the row-level security to take effect, so it takes place after creating the relevant roles. Row-level security does not require upgrading to the Premium SKU. Configure row-level security with the static method - Training | Microsoft Learn
You have created a Power BI dataset and need to create multiple reports. What is a benefit of using a Power BI dataset as a data source for multiple reports compared to each report having a separate dataset? Select only one answer. It reduces the number of datasets, refreshes, and storage requirements in the Power BI service. It increases the speed of the reports and visuals connected to the Power BI datasets. It prevents sensitive data from being shared with report consumers. It increases the number of scheduled refreshes that can be configured for the Power BI dataset.
It reduces the number of datasets, refreshes, and storage requirements in the Power BI service. When multiple reports use the same Power BI dataset vs each having their own import model, you reduce the number of datasets that are needed to be published to the Power BI service. Fewer datasets mean fewer refreshes, less storage space requirements, and less overhead for admins.

You create a Power BI Desktop data source by importing a Cosmos DB for NoSQL item collection. You connect to the Cosmos DB account, database, and collection, but the preview displays only a list of items named Record. You need to select individual fields from items in the collection that you want to load into Power BI Desktop. What should you do first? Select only one answer. Open Power Query Editor. Switch to the model view. Retrieve the Cosmos DB account key. Retrieve the Cosmos DB connection string.
Open Power Query Editor. This behavior is by design. The Preview pane in Power BI shows a list of Record items when connecting to a collection of JSON formatted items. To view individual item fields, open the Power Query window and use the Expander button on the right hand side of the Column1 header to display the list of fields. Switching to the model view would not benefit us in any way, since the data has not been imported yet. Retrieving Cosmos DB account key or connection string at this point is meaningless, since that was required to connect to Cosmos DB account, which has been already completed.

You import data from the Excel spreadsheet into Power BI Desktop. You need to transform the data so it will consist of three columns, with the first one containing month, the second containing year, and the third containing the sales amount for that month and year. Which transformation should you use first? Select only one answer. remove columns transpose table Unpivot Pivot
Unpivot Selecting Unpivot will allow you to shape the current table into the one with the year, month, and sales amount columns, which will need to be renamed afterwards. Pivot would be applicable in the opposite scenario, in which flat data needs to be reorganized into one containing aggregate values for each unique value in each column. Transposing would switch tables and columns. Removing columns would result in a table with insufficient data to perform unpivot.

You create a Power BI data source which uses a SQL SELECT statement. The SQL statement queries multiple tables in a SQL Server database and includes subqueries. After you import data from the data source into Power BI, you notice that one of the columns in the resulting dataset appears blank. You verify that the source table does include data. What should you do to resolve the issue? Select only one answer. Use the CAST function in the SQL statement. Use the DATALENGTH function in the SQL statement. Set the privacy levels on the data source. Clear permissions on the data source in Power BI.
Use the CAST function in the SQL statement. The issue indicates that Power BI is incorrectly interpreting the data type used by the source column. To resolve it, you need to explicitly specify the intended data type, which can be done by using the CAST function. DATALENGTH displays the number of bytes used to represent an expression. Clearing permissions could prevent Power BI from being able to access the target database. Setting the privacy levels of the data source would have no impact on addressing the issue of missing data.

You are evaluating whether you need to create a dashboard in Power BI. In which scenario do you need a dashboard instead of a report in Power BI? Select only one answer. You need to add slicers. You need to add filters. You need to display visuals that use different datasets. You need to display visuals on multiple pages.
You need to display visuals that use different datasets. The ability to combine data from multiple datasets is one of the features that is available in dashboards but not supported in reports. Dashboards do not include the Filter, Visualization, and Fields panes that are available in Power BI Desktop when working with dashboards. Dashboards, unlike reports, contain only a single page.

You need to create a histogram that will display ranges of integers in groups. Which two resources do you need to create the histogram? Each correct answer presents part of the solution. Select all answers that apply. a Numerical column a DateTime column a List group type a Bin group type
a Numerical column a List group type The group is created against a numerical column using bins The Bin group type is an auto grouping of items into bucketed bins (groups). It will display well as a histogram. A DateTime column isn't required to display histogram type data against a numerical column. A List group type is a manual grouping of items into new group names/categories. It doesn't create auto (binned) groups. Explore statistical summary - Training | Microsoft Learn
You have a report in Power BI. You need to adjust the behavior of the report by editing interactions. Which two types of interaction behavior can you change between visuals? Each correct answer presents a complete solution. Select all answers that apply. filter highlight drillthrough expand
filter highlight A filter will show you the filtered data in this visual. Highlight is the default interaction between visuals. It shows you both the unfiltered and filtered values in the visual, for comparison purposes. Drillthrough is a page navigation experience that takes you from one page to another plus applies a set of filters to page navigated to. Expand is a way to navigate down a level using the hierarchy controls.

You plan to create a report in Power BI Desktop that will display sales opportunity by five sales stages, including lead, prospect, qualified, committed, and transacted. You need to identify the type of visualization that will display a linear process with sequentially connected stages, with one stage transitioning to the next. Which visualization should you use? Select only one answer. funnel slicer treemap waterfall
funnel A funnel visualization displays a linear process with sequentially connected stages, with one stage transitioning to the next. A slicer visualization is available in different formats, including list, drop-down, and buttons, but not sequentially connected stages, with one stage transitioning to the next. A treemap visualization displays data a set of nested rectangles. A waterfall visualization displays a running total as values are added or subtracted.

You are designing a data model in Power BI. You need to avoid introducing ambiguity into your data model design. Which type of cardinality should you avoid? Select only one answer. one-to-one one-to-many many-to-one many-to-many
many-to-many Many-to-many cardinality in Power BI should be avoided due to ambiguity, resulting from the presence of non-unique values. One-to-one cardinality in Power BI should be avoided and, if present, should be eliminated by combining the related tables. However, this type does not introduce ambiguity. One-to-many and many-to-one cardinality are two common cardinality types, used for the relationships between a fact and dimension tables.

You have a visual that is being cross-highlighted. By default, what data will be displayed in a report tooltip? Select only one answer. the un-filtered (non-cross-highlighted) total data the filtered (cross-highlighted) data both the un-filtered and filtered (cross-highlighted) data a report page tooltip with cross-highlighted data
the filtered (cross-highlighted) data By default, report tooltips will apply the filter from the cross-highlighted data into the tooltip. Report page tooltips need to be manually created, and are not assigned to a visual by default.
