NEW QUESTION 23
You have a dataset named Pens that contains the following columns:
* Unit Price
* Quantity Ordered
You need to create a visualization that shows the relationship between Unit Price and Quantity Ordered. The solution must highlight orders that have a similar unit price and ordered quantity.
Which type of visualization and which feature should you use? To answer, select the appropriate options in the answer area.

Answer:
Explanation:
Explanation
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.

NEW QUESTION 24
You have a Microsoft Power BI report. The size of PBIX file is 550 MB. The report is accessed by using an App workspace in shared capacity of powerbi.com.
The report uses an imported dataset that contains one fact table. The fact table contains 12 million rows. The dataset is scheduled to refresh twice a day at 08:00 and 17:00.
The report is a single page that contains 15 AppSource visuals and 10 default visuals.
Users say that the report is slow to load the visuals when they access and interact with the report.
You need to recommend a solution to improve the performance of the report.
What should you recommend?
- A. Remove unused columns from tables in the data model.
- B. Change the imported dataset to DirectQuery.
- C. Replace the default visuals with AppSource visuals.
- D. Change any DAX measures to use iterator functions.
Answer: B
Explanation:
DirectQuery: No data is imported or copied into Power BI Desktop.
Import: The selected tables and columns are imported into Power BI Desktop. As you create or interact with a visualization, Power BI Desktop uses the imported data.
Benefits of using DirectQuery
There are a few benefits to using DirectQuery:
* DirectQuery lets you build visualizations over very large datasets, where it would otherwise be unfeasible to first import all the data with pre-aggregation.
* Underlying data changes can require a refresh of data. For some reports, the need to display current data can require large data transfers, making reimporting data unfeasible. By contrast, DirectQuery reports always use current data.
The 1-GB dataset limitation doesn't apply to DirectQuery.
Note:
There are several versions of this question in the exam. The question can have other incorrect answer options, include the following:
* Implement row-level security (RLS)
* Increase the number of times that the dataset is refreshed.

You plan to create the chart shown in the following exhibit.
How should you create the dashed horizontal line denoting the 40th percentile of daily sales for the period shown?
- A. Add a new percentile line that uses Total Sales as the measure and 40% as the percentile.
- B. Add a measure to the visual that uses the following DAX expression.
Heasurel = PERCENTILEX.INC (Sales,Sales[Total Sales],6.40) - C. Add a measure to the visual that uses the following DAX expression.
Heasurel - PERCENTUEX.EXC (Sales,Sales[Total Sales],6.40) - D. Create a horizontal line that has a fixed value of 24,000.
Answer: A
Explanation:
The analytics feature enables you to show percentiles across groups specified along a specific axis.
Example:
1. Click on the analytics tab
2. Select Percentile
3. You can choose a specific percentile along with other formatting options.
4. Drag a date or non-numeric dimension into the Axis of a column chart

NEW QUESTION 27
You have a large dataset that contains more than 1 million rows. The table has a datetime column named Date.
You need to reduce the size of the data model.
What should you do?
- A. Trim the Date column.
- B. Round the hour of the Date column to startOfHour.
- C. Change the data type of the Date column to Text.
- D. Split the Date column into two columns, one that contains only the time and another that contains only the date.
Answer: D
Explanation:
Explanation
We have to separate date & time tables. Also, we don't need to put the time into the date table, because the time is repeated every day.
Split your DateTime column into a separate date & time columns in fact table, so that you can join the date to the date table & the time to the time table. The time need to be converted to the nearest round minute or second so that every time in your data corresponds to a row in your time table.

You can verify this by the status bar at the bottom of the Power query window. To change the profiling so it analyses the entire column of data, select the profiling status in the status bar. Then select Column profiling based on the entire data set.
