About the Azure AZ-305 Exam

The Microsoft Azure Solutions Architect Expert (AZ-305) exam validates advanced expertise in designing comprehensive cloud and hybrid solutions on Azure—spanning identity, governance, storage, compute, networking, business continuity, and security at enterprise scale. Unlike Associate-level certifications (AZ-104 administration, AZ-204 development) which focus on implementation, AZ-305 targets architects responsible for strategic technical decisions—selecting appropriate services based on cost, performance, scalability, and compliance requirements for complex multi-tier applications. This Expert-level certification proves deep architectural knowledge across all Azure services with emphasis on trade-off analysis, high availability design, and enterprise-scale governance.

The exam consists of 40-60 questions (including case studies, multiple-choice, and scenario-based architecture questions) to be completed in 100-120 minutes, with a passing score of 700 out of 1000. The exam costs $165 USD and certifications remain valid for one year. Microsoft requires passing either AZ-104 (Administrator) or AZ-204 (Developer) as a prerequisite before attempting AZ-305—plus extensive hands-on experience architecting Azure solutions. After earning AZ-305, architects typically pursue AZ-400 (DevOps Engineer Expert) or specialize with AZ-500 (Security Engineer).

Exam Domains and Weighting:

  • Domain 1: Design identity, governance, and monitoring solutions (25-30%) - Azure AD architecture (hybrid identity, B2B/B2C, Conditional Access, PIM), governance at scale (management groups, Azure Policy, blueprints, resource locks), cost management (budgets, advisor, reserved instances), monitoring strategies (Azure Monitor, Log Analytics, Application Insights, alerts and action groups)
  • Domain 2: Design data storage solutions (25-30%) - Storage account architecture (redundancy: LRS, ZRS, GRS, RA-GZRS; performance tiers, lifecycle policies), database selection (SQL Database vs. Managed Instance vs. Cosmos DB vs. PostgreSQL, consistency models, replication strategies), data integration (Data Factory, Event Hubs, Data Lake), backup and archival strategies
  • Domain 3: Design business continuity solutions (10-15%) - High availability design (availability zones, availability sets, autoscaling), disaster recovery planning (Azure Site Recovery, backup strategies, RTO/RPO requirements), application resilience patterns (circuit breakers, retry policies, health probes), geo-redundancy and failover strategies
  • Domain 4: Design infrastructure solutions (25-30%) - Compute architecture (VM sizing, scale sets, App Service plans, container strategies: ACI vs. AKS, serverless patterns with Functions), networking design (hub-spoke topology, VNet peering, VPN/ExpressRoute for hybrid, load balancing: Azure Load Balancer vs. Application Gateway vs. Front Door, NSG vs. Azure Firewall), migration strategies (Azure Migrate, assessment and planning)

AZ-305 emphasizes architectural decision-making over hands-on implementation—expect case studies presenting complex business requirements where you must recommend appropriate Azure services, justify architectural choices based on constraints (cost, performance, compliance), and design solutions that balance competing priorities. The exam tests understanding of enterprise patterns like hub-spoke networking, multi-region active-active deployments, zero-trust security architecture, and cost optimization strategies for production workloads at scale.

  • Optimizing costs at scale using reserved instances (1-3 year commitments for predictable workloads), spot VMs (up to 90% discount for interruptible batch processing), autoscaling to match capacity with demand, and lifecycle policies for storage tier optimization
  • Designing zero-trust security architecture with Conditional Access (location, device compliance, risk-based policies), PIM for time-bound privileged access, private endpoints for Azure service isolation from public internet

How to Prepare for the Azure AZ-305 Exam

Azure Solutions Architect Expert requires both deep technical knowledge AND strategic thinking about architectural trade-offs. Unlike Associate exams testing implementation, AZ-305 presents complex case studies with competing requirements—you must recommend solutions balancing cost, performance, security, and operational complexity. Microsoft requires passing AZ-104 or AZ-204 first, plus significant hands-on experience architecting production Azure solutions.

  1. Study Azure Well-Architected Framework (4-5 weeks): Download the official Microsoft AZ-305 exam guide and deeply study all four domains. Master the Azure Well-Architected Framework five pillars (reliability, security, cost optimization, operational excellence, performance efficiency)—these principles underpin every architectural decision tested. Focus on service comparison scenarios: when to use SQL Database vs. Cosmos DB, Application Gateway vs. Front Door, availability zones vs. geo-redundancy, hub-spoke vs. mesh networking.
  2. Architect Real Solutions (6-8 weeks): Design and implement complete Azure architectures addressing realistic scenarios: multi-tier web application with App Service, SQL Database, Redis cache, and Application Gateway; disaster recovery solution with Azure Site Recovery and geo-replicated storage; hybrid connectivity using ExpressRoute with hub-spoke networking and Azure Firewall; multi-region deployment with Front Door, Traffic Manager, and geo-distributed Cosmos DB. Document architectural decisions and trade-offs—the exam tests justification, not just knowledge.
  3. Master Case Study Analysis (2-3 weeks): AZ-305 heavily uses case studies presenting complex business requirements with constraints (budget, compliance, performance SLAs, timeline). Practice analyzing scenarios to identify: stated requirements (must-haves), implied requirements (regulatory compliance, HA/DR), constraints (cost limits, existing infrastructure), and optimal solutions balancing priorities. Use Microsoft Learn case study modules and practice identifying which Azure services satisfy requirements while minimizing cost and complexity.
  4. Practice Exams and Peer Review (1-2 weeks): Take timed practice exams simulating the 100-120 minute experience with case studies. The official Microsoft practice exam ($99 USD) provides realistic scenarios testing architectural decision-making. Review incorrect answers to understand why alternative solutions were suboptimal—often due to overlooked constraints, cost inefficiency, or unnecessary complexity. Consider joining Azure architecture study groups to discuss and defend design decisions, as explaining architectural choices deepens understanding.

Schedule your exam once you can confidently justify architectural decisions, compare Azure services based on requirements, and design solutions addressing complex enterprise scenarios. The AZ-305 exam costs $165 USD with certification valid for one year. After passing, you'll receive a digital badge, exam score report, and access to exclusive Microsoft Certified community benefits.
