It is all over now. NO ONE can lie about being certified by AWS any more. it can all be cross-checked instantly. AWS just provided its cert validation mechanism for anyone to verify directly on the internet here https://www.certmetrics.com/amazon/public/transcript.aspx and they can share cert transcripts, AWS cert badges and so on directly on Linkedin, Facebook etc as well as any other ways to verify instantly. no more waiting reply email any longer. Well done AWS !!! it is now well worth it.
