Best AZ-305 Resources for Azure Solutions Architects
Best Resources to Prepare for Microsoft AZ-305 (Designing Microsoft Azure Infrastructure Solutions)
If you already operate at AZ-104 level and are moving into an architecture role, AZ-305 validates your ability to design secure, scalable, reliable, and cost-optimized solutions on Azure. This guide curates the most effective resources and shows how to combine them into a practical, ethical study plan.
AZ-305 exam at a glance
Official name: Designing Microsoft Azure Infrastructure Solutions (AZ-305)
Role: Azure Solutions Architect (often paired with AZ-104 to earn the Azure Solutions Architect Expert credential)
Status: Active (check the official Microsoft exam page for any changes to skills measured and availability)
Skills measured (high-level): identity, governance, and monitoring; storage and data integration; compute and networking; business continuity and disaster recovery (BCDR); security, reliability, and cost optimization.
Format: Scenario-driven questions (for example, case studies, multiple choice, drag-and-drop). Exact item types and timing may vary.
Registration and policies: Register and review Microsoft’s exam and NDA policies on the official certification site before you book.
Who should take AZ-305?
AZ-305 is designed for experienced Azure administrators, engineers, and consultants who can translate business requirements into end-to-end designs. While there are no formal prerequisites, AZ-104-level knowledge and hands-on experience with Azure networking, identity, storage, governance, and security are strongly recommended.
Curated resources for AZ-305
Prioritize authoritative, first‑party Microsoft content and complement it with structured training and realistic practice.
Microsoft Learn: Role-based learning paths and hands-on modules aligned to AZ-305 domains, including sandbox exercises.
Skills outline (PDF): The definitive list of measured skills. Use it to map your plan and track progress.
Azure Architecture Center: Reference architectures, design patterns, and decision guides for compute, networking, identity, data, and BCDR.
Azure Well-Architected Framework: Pillars (reliability, security, cost optimization, operational excellence, performance efficiency) and assessment tools to stress-test designs.
Azure service documentation: Deep dives on capabilities, SLAs, limits/quotas, deployment models, and configuration options.
Practice tests: Use reputable providers aligned with Microsoft’s objectives (e.g., Microsoft’s official practice test partner) to assess readiness ethically.
Hands-on: Azure free trial, Microsoft Learn sandboxes, and official GitHub reference implementations.
Prefer guided learning? Consider AZ-305 Instructor-led Training with Readynez for expert-led lectures, scenario workshops, and labs mapped to the exam outline.
Courses, practice tests, and how to use them
Blend first‑party docs with guided training and measured practice.
Instructor-led training: Use structured classes to accelerate difficult topics (hybrid networking, governance, BCDR, landing zones). Explore the Readynez AZ-305 course and the broader Microsoft certification training catalog.
Self-paced learning: Work through Microsoft Learn modules and official documentation. Summarize each module and map it back to the skills outline.
Practice tests: Use them as diagnostics, not cramming. After each attempt, remediate using Microsoft Learn and docs before re-testing.
Important: Do not use unauthorized question repositories. They violate Microsoft’s exam policies and NDA and do not build real architectural skill.
Hands-on practice that mirrors real scenarios
Designing solutions is a practical craft. Balance theory with build-and-break cycles. If you don’t have a paid subscription, leverage Microsoft Learn sandboxes or an Azure free trial. You can also consider Readynez Unlimited Microsoft Training if you expect to take multiple Microsoft courses with labs.
Lab ideas by domain
Identity, governance, and monitoring: Design an Azure AD tenant architecture with Conditional Access, PIM/RBAC, Azure Policy, management groups, and Azure Monitor/Log Analytics workspace strategy.
Networking and hybrid connectivity: Implement Hub-Spoke VNets, VNet peering, Private Endpoints, DNS forwarding, VPN or ExpressRoute design considerations, and Azure Firewall vs. NSG decisions.
Compute and application platforms: Compare AKS vs. App Service vs. Azure Functions for a multi-tier web app. Add autoscale rules and deployment slots.
Storage and data: Model a tiered storage strategy (Hot/Cool/Archive), lifecycle policies, Azure Files vs. Blobs, and data integration with Event Grid or Service Bus.
BCDR: Create RTO/RPO targets and implement Azure Backup and Azure Site Recovery. Validate failover plans and run a test failover.
Cost, reliability, and performance: Use pricing and SLA information plus service limits/quotas to right-size designs and choose redundancy options.
A structured 6–8 week AZ-305 study plan
Week 1 — Baseline and plan: Review the skills outline. Take a diagnostic practice test. Revisit AZ-104 topics via the Microsoft training catalog if you have gaps.
Week 2 — Identity, governance, monitoring: Complete Microsoft Learn modules. Build a management group, Policy, and RBAC model. Capture design decisions and trade-offs.
Week 3 — Networking and hybrid: Deep dive on VNet architecture, routing, private access, and hybrid options. Implement a secure Hub-Spoke.
Week 4 — Compute and application platforms: Evaluate hosting options (VMs, App Service, containers, serverless). Map to workload characteristics and SLAs.
Week 5 — Storage and data integration: Design for performance, durability, lifecycle management, encryption, and key management.
Week 6 — BCDR and resilience: Define RTO/RPO, backup, and disaster recovery plans. Test failover/failback.
Week 7 — Cost and reliability optimization: Optimize with reservations, autoscale, right-sizing, and architecture choices. Review Well‑Architected recommendations.
Week 8 — Final readiness: Take full practice tests, remediate weak areas, and run end‑to‑end design walkthroughs. Book the exam only when consistently scoring at your target readiness level.
Milestones: Maintain a design journal, capture assumptions and constraints, and validate decisions against Well‑Architected pillars.
Compare prep options
Official/self-paced learning
Best for: Independent learners who prefer to read, lab, and iterate at their own pace.
Strengths: Always current, scenario-focused, free to start.
Considerations: Requires strong self-discipline and a realistic lab plan.
Instructor-led training
Best for: Professionals who want expert guidance, structured labs, and peer discussion.
Considerations: Use only reputable, policy-compliant providers; remediate between attempts.
Ethical preparation and Microsoft policies
Prepare ethically. Do not use unauthorized question repositories or share exam content. Review Microsoft’s exam policies, retake policy, and NDA on the official site. Your goal is real-world architecture skill, not short‑term memorization.
AZ-305 FAQs
Do I need AZ-104 before AZ-305?
It’s not mandatory but strongly recommended. AZ-305 assumes hands-on proficiency with Azure administration concepts covered in AZ-104.
How long should I study?
Experienced Azure administrators typically plan 6–8 focused weeks, including regular labs. Your timeline may vary based on experience.
What’s the retake policy?
Microsoft publishes the official retake policy on its certification site. Review it before booking to understand wait times and limits.
How is AZ-305 scored?
Microsoft provides scoring guidance on the exam page. Expect scenario-based evaluations across the measured skills.
How often does the exam update?
Microsoft updates skills outlines periodically to reflect Azure changes. Always review the current outline before studying.
Can I lab without a paid subscription?
Yes. Use Microsoft Learn sandboxes for guided modules or start with an Azure free trial. Many scenarios can be validated at low or no cost.
What about AZ-303/304?
AZ-305 replaced AZ-303/304. Those older exams are retired.
