What is Azure AZ-305?
The Microsoft Azure Solutions Architect Expert (AZ-305) certification validates your expertise in designing cloud and hybrid solutions on Azure. It's the pinnacle of Microsoft's Azure infrastructure certifications and demonstrates your ability to architect enterprise-grade solutions. For official exam details, visit the official Microsoft Learn page.
AZ-305 is designed for experienced cloud architects who design solutions that meet business requirements across identity, governance, data, business continuity, and infrastructure. This expert-level exam expects deep AZ experience and strong design skills.
Prerequisites: You must pass AZ-104 (AZ Administrator) to earn the AZ Solutions Architect Expert certification. AZ-305 focuses on design, while AZ-104 covers implementation.
Exam Format & Details
Question Types
- Case Studies: Multi-part scenarios with related questions
- Multiple Choice: Select ONE correct answer
- Multiple Response: Select ALL that apply
- Drag and Drop: Match components or arrange solutions
- Hot Area: Select the correct area in a diagram
Important: AZ-305 emphasizes case studies heavily. You'll be given complex business scenarios and must design appropriate solutions. Focus on understanding trade-offs!
All 4 Exam Domains Explained
AZ AD architecture, governance strategies with management groups and policies, RBAC design, logging architecture, monitoring strategies with AZ Monitor and Log Analytics, cost optimization approaches.
Relational and non-relational data solutions, data integration strategies, data storage for analytics, choosing between AZ SQL, Cosmos DB, Storage, Data Lake, Synapse, and hybrid approaches.
High availability architectures, disaster recovery strategies, RTO/RPO requirements, AZ Backup solutions, AZ Site Recovery, geo-redundancy patterns, and failover designs.
Compute solutions (VMs, containers, serverless), networking architecture (VNets, ExpressRoute, hub-spoke), application architecture, migration strategies, and hybrid connectivity patterns.
Key Design Patterns to Master
Identity & Governance Patterns
- Zero Trust: Never trust, always verify approach
- Least Privilege: Minimal permissions for every identity
- Hub-Spoke Management: Centralized governance with distributed workloads
- Policy-Driven Governance: AZ Policy for compliance at scale
Data Architecture Patterns
- Data Mesh: Domain-oriented data ownership
- Lambda Architecture: Batch + speed layers for analytics
- CQRS: Separate read and write models
- Event Sourcing: Store state as sequence of events
Infrastructure Patterns
- Hub-Spoke Networking: Central hub with connected spokes
- Microservices: Loosely coupled, independently deployable services
- Serverless: Event-driven compute without server management
- Hybrid Cloud: On-premises and cloud integration
