Why Azure

A lot of companies already run on Microsoft, from Windows and Microsoft 365 to Azure, so Azure skills fit straight into the systems many IT teams manage every day. The Fundamentals exams are built for people new to the cloud and make a low-pressure first cert, while AZ-104 is the one for people who run Azure day to day.

The Azure path

Most people start with AZ-900. AZ-104 is the step up for running Azure, and AI-901 covers Azure's AI services. None of them require the one before it.

Questions

AZ-900 is the usual first one. It covers the basics every other Azure exam assumes you know.
If you're new to the cloud, yes. It's a low-pressure way to learn how Azure works and to show employers you know the basics. If you already run Azure at work, you can skip it and go straight to AZ-104.
No. Microsoft doesn't require it, but AZ-104 expects you to already know your way around Azure.
Harder than the Fundamentals exams. It's about doing the work: setting up identities, storage, networks and virtual machines, so hands-on time in Azure helps a lot.
AZ-900 covers Azure as a whole: core services, pricing and security. AI-901 focuses on Azure's AI services and when to use each one.
It depends on what you already know. The table above shows an estimate for each cert, based on studying one or two sections a day.
Yes. You can take them at a testing center or online from home with a remote proctor.
