Question#65

You have a report that contains a donut chart and a clustered column chart. Interactions between the visuals use the default settings.

Answer: B
Filters remove all but the data you want to focus on.
Note: Enable the visual interaction controls.
1. Select a visualization to make it active.
2. Display the Visual Interactions options.
3. In Power BI Desktop, select Format > Edit interactions.

4. To display the visualization interaction controls, select Edit interactions. Power BI adds filter and highlight icons to all of the other visualizations on the report page.
We can see that the tree map is cross-filtering the line chart and the map, and is cross-highlighting the column chart. You can now change how the selected visualization interacts with the other visualizations on the report page.

Question#67

You are creating a Power BI report by using Power BI Desktop.
You need to include a visual that shows trends and other useful information automatically. The visual must update based on selections in other visuals.
Which type of visual should you use?

  • A. Q&A
  • B. smart narrative
  • C. key influencers
  • D. decomposition tree
Discover Answer Hide Answer

Answer: B
The smart narrative visualization helps you quickly summarize visuals and reports. It provides relevant innovative insights that you can customize.
Use smart narrative summaries in your reports to address key takeaways, to point out trends, and to edit the language and format for a specific audience. In
PowerPoint, instead of pasting a screenshot of your report's key takeaways, you can add narratives that are updated with every refresh. Your audience can use the summaries to understand the data, get to key points faster, and explain the data to others.

Question#70

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 have a clustered bar chart that contains a measure named Salary as the value and a field named Employee as the axis. Salary is present in the data as a numerical amount representing US dollars.
You need to create a reference line to show which employees are above the median salary.
Solution: You create a constant line and set the value to .5.
Does this meet the goal?

  • A. Yes
  • B. No
Discover Answer Hide Answer

Answer: B
Instead: You create a percentile line by using the Salary measure and set the percentile to 50%.
