@bvaddi-0711de45 Personally I think it is, however I did supplement it with some re:Invent videos with areas I didn't feel were my strong areas and whitepapers just because thats what I've done all the way through all of the certifications I've achieved.
Must have done something right as I got a decent score on the test too although I had to wait for it to flow in CertMetrics before I could see the score unlike every other one that sent me an email with the score report.
I’d love to endorse/recommend you on LinkedIn if you want. All you have to do is add me as a connection and add Linux Academy as your school. Once you do that, post a picture of your cert about passing in your feed and reference me within the original post. Once I see this, I’ll be able to recommend you for your hard work on your LinkedIn profile.
