Question 1

Is this really free?

Accepted Answer

Yes, no credit card required. The diagnostic, all practice questions, flashcards, and progress tracking are free. Premium adds timed exam simulations and removes daily limits.

Question 2

Do the questions match the actual exam?

Accepted Answer

Every question is crafted to match the AI-901's objectives, style, and difficulty. The goal is confident, well-rounded exam readiness.

Question 3

Do I need AI or Azure experience to start?

Accepted Answer

No. The AI-901 is a fundamentals exam. The diagnostic figures out where you are starting from and focuses your time on the gaps.

Question 4

How long does it take to prepare?

Accepted Answer

Most people are ready in 2 to 6 weeks with 30 minutes a day. Your readiness score tells you when you're ready to book.

Question 5

How is Cert Buddy different?

Accepted Answer

Cert Buddy identifies your focus areas first, then directs practice where you need it most. AI explanations are grounded in current Microsoft Learn documentation, not a stale snapshot. Study streaks, achievement badges, and friendly leaderboards help you stay motivated and keep making progress.

Question 6

How is AI-901 different from AI-900?

Accepted Answer

Microsoft retired the AI-900 exam on June 30, 2026 and replaced it with AI-901. The core AI and machine learning fundamentals from AI-900 are still covered, but AI-901 adds substantial new content on Azure AI Foundry (the unified AI development platform), generative AI (Azure OpenAI Service, prompt engineering, RAG), and agentic AI (AI agents, multi-agent systems, orchestration). The exam is now structured into two skill groups rather than seven separate domains.

Question 7

What is Azure AI Foundry and why does it matter for the exam?

Accepted Answer

Azure AI Foundry is Microsoft's unified platform for building, evaluating, and deploying AI applications and agents on Azure. It covers 55-60% of the AI-901 exam, making it the highest-weight topic. Foundry brings together Azure OpenAI Service, Azure AI Vision, Azure AI Language, Azure AI Speech, Azure AI Document Intelligence, and Azure AI Search into one development environment.

Question 8

What agentic AI topics appear on the AI-901 exam?

Accepted Answer

The AI-901 tests what an AI agent is and how it differs from a chatbot, single-agent versus multi-agent systems, tool calling (function calling) in Azure OpenAI, orchestration frameworks like Semantic Kernel and AutoGen, the Azure AI Foundry Agent Service, and responsible AI considerations for autonomous agents such as human-in-the-loop controls and action boundaries.

Question 9

What responsible AI principles are tested on AI-901?

Accepted Answer

Microsoft's six responsible AI principles are directly tested: Fairness (equitable treatment of all people), Reliability and Safety (consistent and safe behavior), Privacy and Security (data protection), Inclusiveness (benefiting all users), Transparency (understandable systems), and Accountability (human oversight and governance). Expect scenario-based questions that ask which principle applies to a described situation.

Question 10

What score do I need to pass the AI-901?

Accepted Answer

Microsoft requires a score of 700 out of 1000 to pass the AI-901 exam. On the Cert Buddy readiness scale (0-100), a readiness score of 75 or above corresponds to strong exam readiness. The dashboard shows your score trend over time so you can see when you are consistently hitting that threshold.
