powerfool said: Everything that I could find. I have been doing Azure for about 5 years. I go through Ignite sessions every year. I also have an O’Reilly Learning subscription through work, which includes the Skylines Academy stuff and they offered live workshops with Tim Warner. I did sit the MOC for AZ-300, but I was unimpressed; the instructor did give of exercises for both 300/301. I also used the Scott Duffy materials on Udemy, but I couldn’t really recommend those.
