NEW QUESTION 1:
You have a report that contains four pages. Each page contains slicers for the same four fields. Users report that when they select values on a slicer on one page, the visuals are not updated on all the pages.
You need to recommend a solution to ensure that users can select a value once to filter the results on all the pages.
What are two possible recommendations to achieve this goal? Each correct answer presents a complete solution.
NOTE: Each correct selection is worth one point.
A. Sync the slicers across the pages.
B. Replace the slicers with page-level filters.
C. Replace the slicers with visual-level filters.
D. Create a bookmark for each slicer value.
E. Replace the slicers with report-level filters.
Correct Answer: AE
Add a report-level filter to filter an entire report. The visuals on the active page, and on all pages in the report, change to reflect the new filter. You can sync a slicer and use it on any or all pages in a report.
- On the Power BI Desktop View menu, select Sync slicers.
The Sync slicers pane appears between the Filters and Visualization panes.

NEW QUESTION 3:
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, You create a parameter named DataSourceExcel that holds the file name and location of a Microsoft Excel data source.
You need to update the query to reference the parameter instead of multiple hard-coded copies of the location within each query definition.
Solution: In the Power Query M code, you replace references to the Excel file with DataSourceExcel.
Does this meet the goal?
A. Yes
B. No
Correct Answer: A
Instead, modify the source step of the queries to use DataSourceExcel as the file path.
Note: Parameterising a Data Source could be used in many different use cases. From connecting to different data sources defined in Query Parameters to load different combinations of columns.

NEW QUESTION 4:
HOTSPOT
You have a report page that contains the visuals shown in the following exhibit.
Use the drop-down menus to select the answer choice that completes each statement based on the information presented in the graphic.
NOTE: Each correct selection is worth one point.
Hot Area:
Correct Answer:
Box 1: cross-filter
By default, selecting a data point in one visual on a report page will cross-filter or cross-highlight the other visuals on the page.
Box 2: cross-highlight
Example:
By default, selecting a data point in one visual on a report page will cross-filter or cross-highlight the other visuals on the page.
1.
Let\’s see what happens when we select Moderation.
2.
Cross-filtering removes data that doesn\’t apply. Selecting Moderation in the doughnut chart cross-filters the line chart.
The line chart now only displays data points for the Moderation segment.
3.
Cross-highlighting retains all the original data points but dims the portion that does not apply to your selection.
Selecting Moderation in the doughnut chart cross-highlights the column chart. The column chart dims all the data that applies to the Convenience segment and highlights all the data that applies to the Moderation segment.
NEW QUESTION 5:

Box 1: A scatter plot…
A scatter chart always has two value axes to show: one set of numerical data along a horizontal axis and another set of numerical values along a vertical axis. The chart displays points at the intersection of an x and y numerical value, combining these values into single data points. Power BI may distribute these data points evenly or unevenly across the horizontal axis. It depends on the data the chart represents.
Box 2: Automatically find clusters
Scatter charts are a great choice to show patterns in large sets of data, for example by showing linear or non-linear trends, clusters, and outliers.
