Failing Azure Fundamentals (AZ-900) means a 14-day wait and $99 retake fee. Microsoft allows retakes after 14 days for the first 4 attempts, but after 5 failures you must wait 1 year. The good news: Microsoft frequently offers free AZ-900 vouchers through Virtual Training Days, so your retake could potentially be free. This guide walks you through the complete retake process and provides a targeted study plan.
Microsoft's retake policy differs from CompTIA's: 14 days between attempts 1-5. After your 5th failed attempt, you must wait 1 year before trying again. Each attempt costs $99, but check Microsoft's Virtual Training Days—attending these free events often includes a complimentary AZ-900 exam voucher, making your retake completely free.
AZ-900 covers Cloud Concepts (25-30%), Azure Architecture and Services (35-40%), and Azure Management and Governance (30-35%). The exam has 40-60 questions in 85 minutes, including multiple choice, drag-and-drop ordering, and scenario-based yes/no question sets. The 700/1000 passing score means you need approximately 70% correct answers.
Unlike role-based Microsoft certifications, AZ-900 does not expire once earned. This makes it a permanent credential on your resume, which is one reason it remains the most popular Microsoft certification worldwide.
Confusing Azure service categories. Azure offers hundreds of services across compute, storage, networking, databases, AI, and more. Candidates often confuse similar services—like Azure Blob Storage vs Azure Files vs Azure Queue Storage—or cannot identify the correct service for a given scenario. Understanding the primary use case for each major service is essential.
Weak pricing and SLA knowledge. Many candidates focus exclusively on technical services and neglect Azure pricing models, the pricing calculator, TCO (Total Cost of Ownership) calculator, Azure Advisor recommendations, and SLA guarantees. These topics make up a significant portion of the Azure Management and Governance domain.
Cloud concepts confusion. The Cloud Concepts domain tests fundamental cloud knowledge: IaaS vs PaaS vs SaaS, public vs private vs hybrid cloud, high availability, scalability, elasticity, fault tolerance, and disaster recovery. Candidates who jump straight to Azure-specific content without mastering these foundational concepts often struggle.
Governance and compliance gaps. Azure governance tools (Azure Policy, Blueprints, Management Groups, Resource Locks) and compliance features (Microsoft Purview, Defender for Cloud) are heavily tested. Candidates without enterprise IT experience may find these organizational management concepts unfamiliar.
Cloud Concepts (25-30%): Understand the benefits of cloud computing (cost savings, scalability, global reach), the shared responsibility model, and cloud service types. Know the differences between IaaS (you manage OS and apps), PaaS (you manage apps only), and SaaS (vendor manages everything). Study consumption-based pricing vs fixed pricing models.
Azure Architecture and Services (35-40%): This is the largest domain. Know Azure's physical infrastructure (regions, availability zones, region pairs), core services across compute, networking, storage, and databases. Understand Azure identity services (Azure AD/Entra ID, MFA, RBAC, Conditional Access) and Azure security tools (Defender for Cloud, DDoS Protection, Network Security Groups).
Azure Management and Governance (30-35%): Study cost management tools (pricing calculator, TCO calculator, Cost Management, resource tags), governance features (Azure Policy, Blueprints, Management Groups, resource locks), and management tools (Azure Portal, CLI, PowerShell, Cloud Shell, Azure Arc). Understand monitoring with Azure Monitor, Log Analytics, and Azure Advisor.
Microsoft regularly hosts Azure Virtual Training Days—free online events that cover AZ-900 exam objectives over one or two days. Attendees who complete the full training typically receive a free AZ-900 exam voucher via email within a few days. Check the Microsoft Events page for upcoming sessions. These events run frequently (often multiple times per month) and are available globally.
Other sources for free or discounted vouchers include Microsoft Ignite conference challenges, Microsoft Build event challenges, employer training programs, and university partnerships through the Microsoft Imagine Academy. Some Microsoft Learning Partners also offer bundled training courses that include exam vouchers at discounted rates.
AZ-900 uses several question formats beyond standard multiple choice. Yes/No scenario sets present a scenario followed by 3-5 statements you must mark as "Yes" or "No." These are scored as a group—getting one wrong may affect the entire set's score. Read the scenario carefully and apply it consistently across all statements.
Drag-and-drop questions ask you to match services to descriptions or arrange steps in order. Hot area questions show a diagram or screenshot where you click on the correct area. For all question types, read every option carefully before answering—Azure services often have similar names and overlapping features.
14 days for attempts 1-5. After 5 failures, wait 1 year.
$99 USD per attempt. Free vouchers often available through Virtual Training Days.
700 out of 1000, requiring approximately 70% correct answers.
Yes. Microsoft often offers free vouchers through Azure Virtual Training Days events. Check the Microsoft Events page for upcoming sessions.
40-60 questions in 85 minutes, including multiple choice, drag-and-drop, and scenario-based yes/no sets.
AZ-900 is entry-level, but candidates without cloud experience often underestimate the breadth of Azure services, pricing models, and governance concepts tested.
No. Azure Fundamentals does not expire. Fundamentals-level Microsoft certifications have no renewal requirement.
