AI-900:How I Cleared the Microsoft Azure AI Fundamentals Exam in 10 Hr

I successfully passed the Microsoft Azure AI Fundamentals (AI-900) exam with an 80% score after dedicating just 10 hours to preparation. In this post, I’ll walk you through my study approach, resources, and tips.

Exam Overview: AI-900 Microsoft Azure AI Fundamentals

https://learn.microsoft.com/ja-jp/certifications/exams/ai-900
This certification serves as the entry point for individuals seeking to develop foundational skills in artificial intelligence using Microsoft Azure. It validates:

• Core concepts of AI and machine learning
• Awareness of common AI workloads
• Knowledge of Azure AI services such as Cognitive Services, Azure Machine Learning, and AI solution building

Microsoft describes it as a basic-level exam, but you still need to know your concepts well to achieve a high score.

Career (as of 2025)

I work in IT/software and wanted to add Azure AI to my skill set. Before attempting AI-900:

• I hadn’t taken any MCP exams before
• My Azure exposure was zero
• My AI understanding was limited to what I had read or learned informally

Motive

My interest in AI, particularly in image recognition and machine learning applications, led me to pursue this certification.
The other reason? I managed to get a free exam voucher via Microsoft’s Training Days program, making it the perfect opportunity to dive in.

Study Time

Although it’s just “10 hours” in total, I spread them over a few days:

• 2–3 hours each on the first couple of days
• A shorter review session in between
• About 4 focused hours on the final day before the exam

Questions

I can’t disclose the exact questions (due to NDA), but I noticed many were scenario-based, focusing on applying concepts rather than memorization. My preparation aligned well with the type of questions asked.

It was really good. Since it was in English, I used DeepL to translate it. It almost seemed real (although unofficial).

Impressions
The AI-900 helped me clearly understand how Azure integrates AI into practical business solutions. For anyone starting in AI or cloud computing, this is an excellent foundational step.

Summary

This isn’t a particularly difficult certification, but it does require familiarity with AI concepts and Azure’s services.
By focusing on core materials and practicing well, even 10 hours of preparation can lead to success.
