PowerBI CERTIFICATION EXAM 2025 | QUESTIONS
WITH VERIFIED ANSWERS (GRADED A+)
If you want your data to automatically refresh as you interact with visualizations, which option
should you choose?
A) Import
B) DirectQuery - ANSWER - B) DirectQuery
Explanation: When you use DirectQuery, no data is imported into Power BI Desktop. As you
create or interact with a visualization, PowerBI Desktop queries the underlying data source, i.e.
you're always viewing current data.
How do you connect to Excel files that contain target figures? The solution should involve
minimum manual work when new Excel files are created.
A) Connect to the files with Folder connector and use the Combine Binaries functionality.
B) Connect to a new file each month, perform transformations, and use Append function in
Power Query Editor to combine all targets in the same table. - ANSWER - A) Connect to the
files with Folder connector and use the Combine Binaries functionality.
Explanation: Connecting to files separately will take time if there are lots of files in the folder. Its
always better to connect to folder if files have same structure. If you copy new files in that folder
with same structure, that file will be loaded automatically without doing any change to data
sources.
Imagine that you have created a query named "Customers" in a PowerBI Desktop to append the
rowss from three external tables with customer data into a single output table named
