In Power BI Desktop, you limit the data you work with by using parameters. What feature is this describing?

• A. Parameters
• B. Bookmarks
• C. Filters
• D. Calculated columns

Answer: (A)

This describes using parameters to shape the data that gets loaded. In Power BI Desktop, a parameter defines a value that your data source query (via Power Query) uses to limit which rows are retrieved. By setting a parameter for something like a year, region, or range and applying it in the query, you load only the subset of data you need. That pre-load data restriction improves performance and makes it easy to switch between data slices by changing the parameter value.

This is different from filters, which limit data after it has already been loaded into the model; bookmarks, which capture a view state; and calculated columns, which create new data columns after loading.
