# AZ-900 (Azure Fundamentals) Resources

## Knowledge

- [Exam AZ-900 official study guide](https://aka.ms/AZ900-StudyGuide)
  The authoritative skills outline with domain weightings (Cloud concepts 25–30%, Azure architecture & services 35–40%, Management & governance 30–35%) and every sub-topic bullet the exam draws from. Use for: checking any lesson's scope against what's actually tested, tracking exam updates.
- [Exam AZ-900 certification page](https://learn.microsoft.com/en-us/credentials/certifications/azure-fundamentals/) — 45-minute exam, pass mark 700/1000, retake allowed 24h after a fail. Use for: logistics (scheduling, retake policy, accommodations).
- Official 4-part Microsoft Learn "Introduction to Cloud Infrastructure" series — the primary source cited from every lesson:
  - [Part 1: Describe cloud concepts](https://learn.microsoft.com/en-us/training/paths/microsoft-azure-fundamentals-describe-cloud-concepts/) (3 modules)
  - [Part 2: Describe Azure architecture and services](https://learn.microsoft.com/en-us/training/paths/azure-fundamentals-describe-azure-architecture-services/) (5 modules)
  - [Part 3: Describe Azure management and governance](https://learn.microsoft.com/en-us/training/paths/describe-azure-management-governance/) (4 modules)
  - [Part 4: Apply Azure skills in guided projects](https://learn.microsoft.com/en-us/training/paths/introduction-cloud-infrastructure-apply-azure-skills-guided-projects/) (hands-on, free-tier)
  Use for: the deepest read on any single topic; each lesson links the exact module it's compressing.
- [Official free practice assessment](https://learn.microsoft.com/en-us/credentials/certifications/exams/az-900/practice/assessment?assessment-type=practice&assessmentId=23)
  Real question style/difficulty from Microsoft itself. Use for: calibrating exam-readiness in the last few days, not as a first-pass teaching tool.
- [Exam sandbox](https://aka.ms/examdemo)
  Shows the actual exam UI and question types before test day. Use for: removing exam-format surprise once, near the end of prep.
- [John Savill's AZ-900 Azure Fundamentals Certification Course](https://www.classcentral.com/index.php/course/youtube-az-900-azure-fundamentals-certification-course-last-update-apr-2025-514301) (free, YouTube, ~8.5–13 hrs, community-recommended as the strongest free video walkthrough)
  Use for: a fast video pass to reinforce topics after the text lesson, especially in the final review days. Check the upload date shown when you watch — Azure UI/pricing details drift, verify anything time-sensitive against the official docs above.

## Wisdom (Communities)

- [Microsoft Q&A – Azure](https://learn.microsoft.com/en-us/answers/products/) (official Microsoft forum, linked directly from the study guide)
  Use for: asking specific "why does X work this way" questions; moderated by Microsoft staff and MVPs.
- [r/AZURE](https://reddit.com/r/AZURE) (general Azure subreddit)
  Use for: informal exam-experience threads, gut-checks on confusing concepts. Not yet confirmed active/high-signal specifically for AZ-900 — treat as secondary to Microsoft Q&A.

## Gaps

- No confirmed high-signal, AZ-900-specific community was found (e.g. a dedicated certification subreddit) — Microsoft Q&A is the safer default until one is validated.
