>Do trainings teach actually exclusive content? Depends, but sually the answer is: No, they don't. Most of the knowledge was generated and released at some point. Plus, trainings teach what's safe, reliable knowledge. Simply from that perspective, any intelligent person with enough time on their hands, and the inclination to do so can learn all relevant info by themselves. >Do certifications actually boost my portfolio? Yes and No. On the one hand, good certs serve as proof that a candidate knows about a topic. On the other hand, if a candidate has a pile of certifications, but little else, that raises a red flag for some people, because there is such a thing as "learning for the test".
