The function createUser() specifies role:“readwrite” with a lowercase w, one of the correct answer is readWrite with an uppercase W.
I thought it was a trap. But if readWrite is a valid answer then the createUser() must be corrected, unless roles are not case sensitive. Are they?
They’re definitely case-sensitive… I tested this same question on versions 3.6, 4.0 and 4.1. So it must be a typo. In the actual exam, you won’t get any “case sEnSiTiVe” trick question.
