I'm passing this question along to the curriculum design team for you.

Hi Marc.

Thanks for noticing this. For the Knowledge Management part the exam focuses on the 7.1.4 version of KM where the stages where Author > Approve > Publish.  The best place ot see the types of questions asked is the Practice Exam which you can take on Pega Academy.  We are currently working on an update to this course on 7.2 with the goal of having it out by the end of July. 

thanks again.
