Yes,an exact match should be produced in matrix match.The ans could comprise of one/more options in matrix match.For example,if the ans of pt. a is p,q,s and you have matched only p,q then you would not get any marks and no mark would be deducted.Same is for multiple answer type questions,if the correct options are A,B,D and you have ticked  only A,D then neither u would get any marks nor any mark would be deducted.

Normally the pattern changes every year,but generally,multiple choice questions with one or more correct answers,matrix match and single integer type questions do not have any negative marking.
