From what I have learned and what I know the vapor barrier should be placed on the "warm" side of the insulation (which to me would include the rigid insulation), but according to the prctice exam it is only placed on the batt insulation.  This seems to be a conflict to me, does the rigid insulation not count???

  What is this detail?  There's a roof membrane on the left side of the wall (?). Perhaps it's a roof?

  this one also confused me. it's a wall detail. See below for question.

  "An architect is designing a municipal services building in a location that has mild winters and hot, humid summers. The client insists that a sheet membrane vapor retarder of controlled permeability be specified for the exterior walls of the building.

  Click on the area in the exterior wall detail to indicate where the vapor retarder should be applied."

  In addition, should the plywood be next to the stud?
