Hi,
I was doing the dba practice test and then I found the attached question
Can someone tell me why I am wrong?

Mohamed
Does document 1 have E? (Does document 1 have $all the letters from the array E,U)
Does document 3 have U? (Does document 3 have $all the letters from the array E,U)
And finally does document 2 have both E and U? (Does document 2 have $all the letters from the array E,Y)
Hi Mohamed,
look carefully at the question, it doesn’t ask “how many documents” but “which document(s)” , and the document number 2 is the only one that satisfy the query
i hope i have been of some help
see you!

You can read about the $all
operator.
And I’d highly suggest that you take all the courses in the DBA Learning Path before attempting the practice exams.
Hi Giulio,
You are right.
Thanks alot.
