Detailed Review Of Preparation

AZ900 is the only beginner level 1 star exam offered by MS for its Azure cloud platform.

Intended to educate those with absolutely no introduction to cloud, the learning material on the official MS learn site and youtube videos (Tim Warner) is more than enough. 

The exam had 31 questions for me, finished it in ~45 mins. 

I would suggest starting the process half an hour in advance to ensure there are no glitches.
