What is AZ-305?

The AZ-305: Designing Microsoft Azure Infrastructure Solutions is a certification offered by Microsoft for professionals who want to demonstrate their expertise in designing cloud architecture. It’s part of the Microsoft Certified: Azure Solutions Architect Expert certification path.

To take AZ-305, you should already have passed AZ-104: Microsoft Azure Administrator or have equivalent knowledge of Azure administration.

Why AZ-305 Matters

Cloud architecture is at the heart of digital transformation. With businesses migrating to the cloud, the demand for skilled Azure architects is soaring. The AZ-305 certification proves that you can:

  • Design identity, governance, and monitoring solutions
  • Design data storage solutions
  • Design business continuity solutions
  • Design infrastructure solutions

This makes you a valuable asset to any organization leveraging Azure.

Key Concepts Covered in AZ-305

Core areas you’ll need to master:

1. Design Identity, Governance, and Monitoring Solutions

This domain focuses on:

  • Azure Active Directory (AAD): Understand identity protection, conditional access, and hybrid identity.
  • Role-Based Access Control (RBAC): Design access strategies for users and services.
  • Azure Policy & Blueprints: Implement governance across subscriptions.
  • Monitoring & Logging: Use Azure Monitor, Log Analytics, and Application Insights to track performance and diagnose issues.

2. Design Data Storage Solutions

You’ll need to evaluate and design storage strategies using:

  • Azure Blob Storage, Files, and Disks
  • Azure SQL Database, Cosmos DB, and Synapse Analytics
  • Data redundancy and replication
  • Security and compliance for data storage

Understanding the trade-offs between performance, cost, and scalability is key here.

3. Design Business Continuity Solutions

This section tests your ability to ensure high availability and disaster recovery:

  • Backup and Restore strategies
  • Geo-redundancy and failover
  • Azure Site Recovery
  • Designing for SLA and RTO/RPO requirements

You’ll need to design solutions that keep businesses running even during outages.

4. Design Infrastructure Solutions

This is the most technical domain, covering:

  • Networking: VNETs, VPNs, ExpressRoute, and Azure Firewall
  • Compute: Azure VMs, App Services, Functions, and Kubernetes (AKS)
  • Load Balancing and Traffic Management
  • Hybrid and multi-cloud architecture

You’ll be expected to design scalable and secure infrastructure that meets business needs.

Who Should Take the AZ-305 Certification?

This certification is ideal for:

  • Cloud Architects
  • Infrastructure Engineers
  • DevOps Engineers
  • IT Professionals transitioning to cloud roles

If you’re already familiar with Azure services and want to move into architecture and design, AZ-305 is the next logical step.

How to Prepare for AZ-305

1. Understand the Exam Objectives

Start by reviewing the official Microsoft AZ-305 exam guide. It outlines the skills measured and gives you a roadmap for preparation.
