From LimeSurvey Manual
To understand how the LimeSurvey quota system works, think of a survey that contains a "Yes or No" question and an Array question, each of them belonging to two different question groups. You set a quota on this survey that contains a restriction of 20 users who have answered "Yes" to this question. The quota will be checked every time someone answers "Yes" to that question.
