A couple of weeks ago I’ve passed both the AZ-300 and AZ-301 exams. You’re required to pass both of these exams in to get the Azure Solutions Architect Expert certification. After posting a tweet I got a lot of responses asking if I had any pointers on what to learn. Instead of responding to each person individually it makes more sense to share what I’ve used to study and hopefully it’s helpful to others also.

If you’ve read my earlier post on authentication of actions invoked in a Microsoft Teams MessageCard, you’ve probably seen the only useful information we get in the user’s token is the Object Id (`oid`).
