you have right, the correct answer is 9, 10. For first area the answer is 9 because we need to look at the column Source.Name and we can see 9 distinct, 0 unique. For second area the answer is 10 because it is selected <Column Profile> for column Date (View meniu) and also we can identify the same answer with <Column Distribution>.

This is not correct. The 'Count' is showing 90 rows (meaning csv files). 'Distinct' shows 10. So the answer is: 90 & 10.

90 rows are shown for Date column, not for csv files. See the highlighted column

The source.name has 9 distinct values. That's why I think there are 9 files.

I think the answer should be Box1:90 and Box2:10. Each row in the table is one CSV file. The answer for Box1 is about the number of rows(which includes duplicates), not the distinct values of a column. This Count can be found under the Column stats below the table as COUNT 90. The second box is distinct count based on the Date Column which is 10.

But those 90 are ROWs not FILEs. It states in the question they are coming from a folder. You can't have two files with the same name in a folder, so its 9. I personally agree with the answer.

The answer is 90. How can you get 90 rows from a folder if there are only 9 files? doesnt make sense. It could be that the files are from different subfolders, but they have the same name. regardless, they are still separate files, with same name, on different folders.

There can't be 9 CSV files for the simple fact that the date is a refresh date happening at different intervals. So every refresh will generate another CSV file. The answer is 90.

My Answer is 10 & 90:: 1) For each day / date two file (8am & 6pm) - for 5 days min is 2018-01-01 8:00:00AM & max is 2018-05-01 6:00:00 PM (Observe the bar in the columns profile) - each file contains the 9 transactions 2) Date columns (Data type - date/Time) - this filed doesn't have duplicate values - if you use the option to remove duplicate against this columns will not Impact the count Tested

Since the total count is 90 and as per value distribution it is uniform for all dates so answer would be 90/10= 9 and removing duplicates would result in 10 distinct values
