A very good point, and one worth pointing out to ISC2. Just about to kick off a 12 week study group, to assist candidates, because here in New Zealand cloud is a key skill requirement.
I (provisionally) passed the exam on Feb 22 2018, I do agree with most of your conclusions, but I put it to words slightly different.
I don't think it is possible to pass the exam on studying the CBK + practice questions only.
Excuse me, could you answer a little question? During ordering an exam Pearson VUE requires to fill the "Employer" field as mandatory (*). I can't see this in ISC2 requirements. What do you think it's possible to order the exam being unemployed?
