Microsoft Power BI Data Analyst Practice Question

While profiling a Customers table in Power Query Editor, you need to verify that the EmailAddress column contains no duplicates before designating it as a key. You want a quick visual that shows, directly beneath every column header, the total count of distinct values and how many of those are unique (appear only once). Which data-profiling view should you enable from the View ribbon to obtain this information?

  • Enable Column quality; it highlights valid, error, and empty percentages only.

  • Enable Column distribution; it displays Distinct and Unique counts beneath each column.

  • Enable Column profile; it shows detailed statistics but only for the column you select.

  • Turn on the Data preview (top 1,000 rows) option; it automatically pivots each distinct value into a new column.
