I just updated my certification by taking the exam on Friday. I would say the difficulty is on par with the 7.1 version of the exam however there has been quite a change to the format of the exam. There are no TrueFalse questions. Most of the questions are scenario based where you are trying to provide a solution to a problem however it take a fair amount of time to read through the questions and answers. I needed almost the entire 90 minutes to complete the exam!
In addition, there are also some matching questions that is new for certifications written for 7.2.
