+AZURE FUNDAMENTALS (AZ-900):
+- Cloud concepts: IaaS, PaaS, SaaS, public/private/hybrid cloud
+- Core Azure services: Compute (VMs, App Service, Functions, AKS), Storage (Blob, Files, Disk, Archive), Networking (VNet, VPN, ExpressRoute), Databases (SQL DB, Cosmos DB)
+- Azure management: Portal, CLI, PowerShell, ARM templates, Azure Resource Manager
+- Security: Azure AD/Entra ID, RBAC, MFA, Security Center, Key Vault, NSGs
+- Pricing: Subscriptions, resource groups, cost management, TCO calculator, pricing calculator
+- Governance: Azure Policy, Blueprints, Management Groups, Tags
+- Compliance: Trust Center, compliance offerings, data residency
+
+DECISION PRINCIPLES:
+1. Microsoft ALWAYS recommends PaaS over IaaS when possible (more managed, less overhead)
+2. For serverless: Azure Functions > Logic Apps for code-based logic
+3. For storage: Blob for unstructured data, Azure Files for SMB shares, Disk for VMs
+4. For databases: SQL Database for relational, Cosmos DB for globally distributed NoSQL
+5. For identity: Azure AD/Entra ID is the central identity service
+6. For security: Defense in depth - use multiple layers (NSG, firewalls, encryption)
+7. For cost optimization: Reserved instances, spot VMs, auto-scaling, Azure Advisor recommendations
+8. For high availability: Availability Zones > Availability Sets > single VMs
+9. For hybrid: ExpressRoute > VPN for predictable performance and higher bandwidth
+10. For compliance: Choose regions based on data residency requirements
 
 When answering:
-1. Consider Microsoft's official recommendations and best practices
+- Consider the Well-Architected Framework: Cost Optimization, Operational Excellence, Performance Efficiency, Reliability, Security
-2. Think about the Azure Well-Architected Framework (cost, security, reliability, performance, operations)
+- Think about what Microsoft would recommend in official documentation
-3. For scenario questions, identify key requirements, constraints, and priorities
+- For "select all" questions, be thorough - multiple answers are usually correct
-4. Choose the MOST Azure-native and recommended solution
+- Pay attention to key words: "cheapest" = lower tier, "most secure" = multiple layers, "fastest" = premium tiers`;
-5. If multiple answers seem viable, pick the one Microsoft would recommend in their official docs
 
-Example:
+    const userPrompt = `${instructions}
-Q: Which Azure service provides serverless compute?
+${answerCount}
-Options: A. Azure Virtual Machines B. Azure Functions C. Azure App Service D. Azure Batch
-Analysis: Looking for serverless - Azure Functions is the correct answer as it's fully serverless (no VM management)
-Answer: B`;

+3. Consider Microsoft best practices and official recommendations
+4. For each remaining option, evaluate against Azure principles
+5. Choose the answer(s) that Microsoft would recommend
