What DAX function is used to filter a table based on specific criteria?

• A. SUM
• B. FILTER
• C. CALCULATE
• D. VALUES

Answer: (B)

The DAX function used to filter a table based on specific criteria is FILTER. The FILTER function is designed to return a table that includes only the rows that meet a specific condition defined by a boolean expression. By applying this function, you can create more complex calculations or visualizations based on subsets of data, allowing for tailored insights and logic to be applied to your models. When you use FILTER, you specify the table you want to filter and the condition that must be met for rows to be included in the output. The result can then be used in various contexts, such as measures or calculated columns, enabling dynamic calculations that react to selections and slicers within your reports. Other functions included in the options play different roles: SUM is used for aggregating values in a column, CALCULATE changes the context in which the data is evaluated, and VALUES returns a one-column table that contains the distinct values from a specified column. While these functions are powerful within DAX, they do not specifically provide the capability to filter a table based on specified criteria like the FILTER function does.
