Question 1 of 145

You create a KPI visualization in Power BI Desktop that uses the month as the trend axis.

You discover that the data is not sorted by month.

You need to change the sort order of the visualization.

What should you do first?

Answer choices
Show answer

Correct answer: A

To address the sort order issue in a KPI visualization in Power BI, the initial step is to change the visualization to a different type that supports sorting. Once the data is sorted appropriately by month in that visualization, you can then convert it back to the KPI visualization. This approach is necessary because the KPI visualization in Power BI does not have native sorting options.

Question 2 of 145

You have a Power BI model for sales data. You create a measure to calculate the year-to-date sales.

You need to compare the year-to-date sales with the previous year for the same time period.

Which DAX function should you use?

Answer choices
Show answer

Correct answer: A

To compare year-to-date sales with the previous year for the same time period, you should use the DATEADD function. The DATEADD function in DAX is used to shift a column of dates by a specified number of intervals (in this case, years), allowing you to compare measures over similar periods in different years. You would use DATEADD to move the current year's YTD range back by one year to perform this comparison.

Question 3 of 145

You have an on-premises Power BI Report Server.

You plan to create a report in Power BI Desktop and publish the report to the report server.

Which data source should the report use?

Answer choices
Show answer

Correct answer: B

When creating a report in Power BI Desktop and planning to publish it to an on-premises Power BI Report Server, the most suitable and commonly used data source is a Microsoft SQL Server database. This is because it seamlessly integrates with on-premises infrastructures and provides robust capabilities for data management, security, and performance. SQL Server is a traditional and reliable choice for on-premises environments, making it the preferred data source for this scenario.

Question 4 of 145

You have a Power BI report in an app workspace.

You plan to embed a report from the app workspace into a line-of-business application by using Power BI Embedded.

Which information should you provide to the application developers?

Answer choices
Show answer

Correct answer: D

To embed a Power BI report from an app workspace into a line-of-business application using Power BI Embedded, the application developers need the access key and the report ID. This is because the access key is used for authentication to ensure secure access, and the report ID specifies which report to embed. Other pieces of information like the report URL or app workspace name aren't necessary for embedding reports in this context as they do not provide the necessary authentication and identification information.

Question 5 of 145

You have a Power BI model for sales data.

You need to create a measure to calculate the year-to-date sales and to compare those sales to the previous year for the same time period.

Which DAX function should you use?

Answer choices
Show answer

Correct answer: C

To calculate year-to-date (YTD) sales and compare those to the previous year for the same period, the DAX function DATESYTD should be used. The DATESYTD function calculates the year-to-date value, and it can be combined with other time intelligence functions such as SAMEPERIODLASTYEAR to compare the current YTD sales to the previous year's YTD sales for the same period. The PARALLELPERIOD and PREVIOUSYEAR functions are not suitable for this task as they do not account for the running total up to the current date. The SAMEPERIODLASTYEAR function alone does not calculate the YTD value either. Therefore, the most appropriate function to start with is DATESYTD.

Stories from the certified

Charles Sirois
Canada
As this was my first certification exam, I was understandably nervous about what to expect. These study materials made the preparation process much easier, and many of the questions closely reflected those on the actual exam.
Lance Chambers
United States
Wasted about a month going through the free dump sites scattered all over reddit, half the answers were wrong and the other half were for a version of the exam that doesn't even exist anymore. Eventually gave in and paid the small fee here, and the difference was night and day.
Alisha Kelly
Italy
Honestly, I had already gone through the official documentation quite thoroughly, but still didn't feel fully confident going in. This helped things finally click for me. I realized I knew the material, but just hadn't connected all the pieces yet.
Casper Claassen
Netherlands
Used this along with Microsoft Learn and the combo worked really well. The practice questions made the stuff I'd read actually stick. Passed first attempt, no complaints from me.
Gabriele Ghesla
Italy
The content is accurate and clearly presented, and it's more affordable than competitors. The team has been incredibly responsive whenever I've had an issue, and they've been open to small changes that improve the platform.
