72. Explain Bi-directional cross-filtering in Power BI.

AnsIn Power BI, bi-directional cross-filtering is supported by Power BI Desktop, which enables data modelers to apply filters on the table relationships. It is bi-directional because it filters connections in both directions. Moreover, it makes the data modelers' job much easier, where they can solve complex problems without using DAX formulas. 

73. Define the basic concepts of DAX.

Ans: Three basic DAX concepts in Power BI are essential to know. They are Syntax, Functions, and Context.


It is helpful to write the formula or a code. It consists of various functions such as SUM, MAX, MIN, AVG, etc. If the Syntax is written wrong, you'll get an error message in return.


The functions in DAX are similar to Excel functions or arguments, which are used as a formula. These functions use certain values in a specific order to perform calculations. Further, there are various categories: date and time, logical, mathematical data, statistical data, text, and others.


The contexts row and filter are the two different kinds of contexts in DAX. When a formula's Function applies a filter to locate a row in the table, row context is applied. Filter context is employed when one or many filters are used to obtain a value.

82. Explain data sources in Power Map.

AnsThe data might be in Excel format, or it can be presented outside. To competently prepare the data, you must ensure that it is all within the form of an Excel table, with each row indicating a distinctive record. Further, your headings of rows or columns must contain text rather than actual (real) data. It helps Power Map comprehend it accurately when plotting the geographical (correlates) coordinates. When designing a tour within the "Power Map Tour Editor" window, using relevant labels gives you access to value and other category fields.

Moreover, you can load data from the outside source by following these steps:

  • Start Excel, click on "Data," and then the "Get External Data" set for the connection you want to create.
  • A wizard's door will open, where you can follow the instructions.
  • To append the same data to the "Data Model" in the final step of this process, Check the box next.

83. What is the use of the FILTER function in Power BI?

AnsThe FILTER function in Power BI returns a table consisting of a filter condition for each source table row. Further, this Function is hardly used in isolation; instead, it is used as a parameter to other power bi DAX functions like CALCULATE.
