Are there Azure whitepapers which you can advise to study as a prep for the exam?
E.g. as a preparation for the for the AWS Practitioner exam we got an advise to read a couple of whitepapers such as Overview of Amazon Web Services || Architecting for the Cloud: AWS Best Practices || How AWS Pricing Works. I am trying to find something similar for the Azure fundamentals exam.
That is a great question. Microsoft, and Azure, don’t have white papers in the same way as AWS. While there a lot of Microsoft white papers, they tend to be more case study based, and more high level. Not really targeting the AZ-900 level.
As Stephen mentioned, the Azure fundamentals resources are pretty good too, so check those out.
Janusz you could look at the fundamentals skills here https://docs.microsoft.com/en-us/learn/certifications/azure-fundamentals go to the section and download the certification pdf.
Whilst I posted about the exam guide you can also go through the free fundamentals course. I am not sure about white papers but there is a documentation section here https://docs.microsoft.com/en-us/azure/
