I use this method exclusively in the real world and lab practice. It is
easier for us since we multiple vendors and the other vendors authenticate
per interface. Just as long as you know the other ways you will be OK on the
lab. Keep in mind that if the question does not point you towards one or the
other you are better off asking the proctor rather than assuming.
