Not able to find AZ-900 Course

Hello… I was planning to start Azure with az-900 but I see only az-104 course available. will az-104 cover everything required for 900 ? Also some topics are difficult to understand while starting az-104 directly.

Please comment…

AZ-900 is very basic fundamentals of Azure and Cloud computing. For now you can follow the self paced learning at Microsoft Learn:
