AZ-900, AI-901, SC-900 or AZ-104: choosing your first Microsoft credential

Some holders collect every Fundamentals exam in a row without a goal. Others stop at AZ-900 when their career clearly needs a role-based credential. A written goal tells you which exam, and when to stop.

What Microsoft credentials sit around AZ-900?

Microsoft groups its credentials into Fundamentals, role-based Associate and Expert levels, and Specialty credentials. AZ-900 is the Azure entry point. Above it, Azure Administrator Associate (AZ-104) is the usual next step for technical roles.

Your goal decides whether AZ-900 is the right tool. Four goals are common: a first, structured step into cloud work, an understanding of Azure decisions in a business role, an employer or partner programme that asks for it, and a base before AZ-104. AZ-900 serves all four. It is weakest for someone who already administers Azure every day.

Which exam suits which situation?

Microsoft retired Microsoft 365 Fundamentals (MS-900) on 31 March 2026 and replaced AI-900 with AI-901. If a course or an advert still mentions those, it is out of date. Exam codes change, so check Microsoft Learn for the current code before you plan.

What next, by goal?

Check Microsoft Learn for current exam codes before you plan, because Microsoft replaces exams regularly.

How did two colleagues choose?

Tarek had managed his company's Azure subscriptions for three years. His fit test pointed past the Fundamentals level, so he chose AZ-104. Lubna, a finance analyst in the same company, chose AZ-900 to follow the monthly cost reviews. Same company, same cloud, different goals.

When should you stop collecting?

For business roles, AZ-900 is often enough, and experience with real cloud costs adds more. For technical roles, one role-based credential plus a year of hands-on work outweighs several Fundamentals exams. Hussein, in the book, passed AZ-900 as a help desk technician. His goal was administration, so he spent a year handling Azure tickets at work and then passed AZ-104, which his employer paid for.

How do you decide in practice?

Ask three short questions before you pay.

1. Will an employer, partner programme or promotion decision turn on this credential within a year? If yes, the exam has a purpose.
2. Is my real gap understanding or doing? Understanding gaps (what a service is for, who secures it, how it is billed) fit AZ-900. Doing gaps fit hands-on work and AZ-104.
3. Could the hours do more elsewhere? Following a monthly Azure cost review at work can teach as much as an exam.

Write the answers in your decision record, with your target month and a review date. If the record says AZ-900, the study plan guide turns it into a dated schedule.

What about the other cloud?

Azure and AWS teach the same ideas in different vocabularies, and the two foundational exams overlap in concepts: shared responsibility, regions, pricing models, identity and cost tools. If your employer runs mainly on AWS, start there; a second platform can wait until your job spans both. See CredenTrek For AWS Cloud Practitioner.

For security careers, CompTIA Security+ may serve you better this year, with AZ-900 added later. If you are new to IT altogether, CompTIA A+ builds general foundations. When you have chosen, check your materials with the July 2026 changes guide, then read the exam map. The first guide in this series, Is AZ-900 worth it?, has the fit test.
