Microsoft Certified: Azure Solutions Architect Expert (AZ-305): How to Earn the Certification

Group classes
  • Confirm that the current target is Microsoft Certified: Azure Solutions Architect Expert through AZ-305, rather than the retired AZ-303 and AZ-304 path.
  • Build preparation around design judgement, hands-on Azure architecture practice, cost control and renewal planning.
  • Use Microsoft Learn as the source of record for exam objectives, certification status and renewal requirements.

The Microsoft Certified: Azure Solutions Architect Expert credential is a certification for professionals who design Azure infrastructure solutions across identity, governance, data storage, business continuity and core infrastructure. Last updated: 2026. It is aimed at people who can make design decisions rather than simply operate individual Azure services.

The current certification path centers on AZ-305: Designing Microsoft Azure Infrastructure Solutions. Older references to AZ-303 and AZ-304 should be treated as historical, including archived Azure architect training pages for AZ-303 and AZ-304 and any retired exam references that still appear online. Microsoft Learn remains the source of record for the active certification, and the Microsoft Azure Solutions Architect certification page should be checked before booking an exam or planning renewal.

What the Azure Solutions Architect role actually involves

An Azure Solutions Architect is responsible for turning business, security, operational and cost requirements into workable Azure designs. The work usually includes choosing identity patterns, designing network connectivity, selecting storage and compute services, planning resilience, shaping governance and making sure operations teams can support what gets deployed.

In practice, the role is full of trade-offs. A design that maximizes availability can increase cost and operational complexity. A migration design that looks simple in a diagram may become harder once legacy authentication, network latency, data gravity or regulatory constraints are included. Good architecture work therefore depends on explaining why a design fits the requirements, not simply naming the Azure service that could be used.

Microsoft’s Well-Architected Framework is useful because it frames architecture decisions around reliability, security, cost optimization, operational excellence and performance efficiency. The Cloud Adoption Framework adds another practical layer by connecting architecture with landing zones, governance, migration planning and operating models. AZ-305 reflects that kind of thinking: candidates are expected to evaluate options and constraints rather than memorize product descriptions in isolation.

How AZ-305 maps to real architecture work

AZ-305 measures design skills across identity and governance, data storage, business continuity and infrastructure. These domains map directly to work that architects carry out in Azure environments: designing landing zones, setting Azure Policy and RBAC boundaries, integrating Microsoft Entra ID, planning backup and recovery with Recovery Services vaults, selecting data platforms and deciding how infrastructure should be represented through Bicep, Terraform or another infrastructure-as-code approach.

A typical landing zone decision shows the nature of the exam. The architect may need to decide how management groups should reflect the organization, where policies should be enforced, which teams need delegated access and how subscriptions should be separated for production, development and shared services. None of those decisions can be made well by memorizing one service. They require an understanding of governance, identity, network design, operations and cost impact together.

Architecture area Typical AZ-305 design decision Real-world consideration
Identity and governance Design Microsoft Entra ID, RBAC, management groups and policy assignments. Access models must match operating responsibilities and audit requirements.
Networking and compute Choose connectivity, segmentation, private access and hosting patterns. Hybrid routing, name resolution and latency often shape the final design.
Storage and data Select storage services, redundancy options and data access patterns. Cost, resilience, compliance and application behavior need to be balanced.
Business continuity Design backup, disaster recovery and high availability approaches. Recovery objectives must be realistic for the workload and budget.

This is also where many candidates underestimate the exam. AZ-305 is less forgiving when preparation is built around recognizing service names only. Case-study style questions often include governance constraints, existing on-premises dependencies, identity boundaries or cost pressure. The stronger preparation habit is to ask what requirement is driving the design, what constraint limits the options and what operational consequence follows from the recommendation.

Experience matters, even where formal prerequisites have changed

The current certification path should not be confused with the older two-exam route. AZ-303 and AZ-304 have been retired, and AZ-305 is now the relevant exam for the Azure Solutions Architect Expert certification. Microsoft changes certification requirements over time, so candidates should verify the current mapping on Microsoft Learn before committing to a study plan.

Although formal prerequisite requirements have changed, experience remains important. Candidates are usually better prepared when they already understand Azure administration at a level similar to AZ-104, including virtual networks, storage accounts, compute resources, identity, monitoring and basic security controls. Without that foundation, AZ-305 preparation can feel abstract because the exam asks why a design should be chosen, not only how a resource is configured.

Infrastructure professionals coming from on-premises backgrounds often bring useful strengths, especially in networking, virtualization, backup, directory services and operational resilience. The transition challenge is learning how Azure expresses those same concerns through subscriptions, management groups, policy, managed identities, platform services and region-pairing decisions. That shift is one reason hands-on lab work is more valuable than reading alone.

A realistic 8–10 week preparation plan

An 8–10 week plan is a reasonable guide for professionals who already have Azure administration experience and can study consistently. It should be treated as planning guidance rather than a promise, because the right pace depends on prior exposure to Azure networking, identity, governance and disaster recovery.

The most effective plan combines Microsoft Learn modules, exam objective review, hands-on Azure labs and scenario-based practice. Structured training can help when candidates want a guided route through the material; Readynez, for example, provides Microsoft training options, while self-study candidates can use the Microsoft certification roadmap and related resources to compare where AZ-305 sits among other Microsoft credentials. The important point is that the study method should force architectural decisions, not passive reading.

Period Study focus Lab milestone
Weeks 1–2 Review the AZ-305 skills outline, Azure landing zone concepts, Microsoft Entra ID, RBAC, management groups and Azure Policy. Create a small subscription structure, apply policy assignments and test role separation with least-privilege access.
Weeks 3–4 Study network architecture, private connectivity, hybrid access, compute hosting choices and monitoring design. Build a hub-and-spoke style lab using virtual networks, private endpoints where appropriate and monitoring alerts.
Weeks 5–6 Focus on storage, database platform choices, redundancy, backup and disaster recovery planning. Configure storage redundancy options, backup policies and a recovery scenario using a non-production workload.
Weeks 7–8 Work through case-study questions, compare design alternatives and revisit weak domains. Document a workload design with identity, network, governance, resilience and cost assumptions.
Weeks 9–10 Use practice questions ethically, review Microsoft Learn updates and refine exam pacing. Repeat one end-to-end architecture scenario and explain each design choice in writing.

Lab work should be small, deliberate and cost-controlled. Candidates should use budgets, spend alerts, free service allowances where available, automatic shutdown for virtual machines and resource groups that can be deleted after each exercise. Cost governance is part of the architect mindset; skipping it during preparation can create a blind spot because AZ-305 frequently expects cost-aware design thinking.

What to practise in a lab

A useful AZ-305 lab does not need to resemble a production enterprise environment. It should model the decision points an architect needs to understand: how access is granted, how policy prevents drift, how a workload reaches private services, how monitoring signals are collected and how a recovery plan would work after failure.

One practical topology is a small landing zone simulation. It can include a management group structure, separate subscriptions or resource groups for shared and workload services, a virtual network design with segmented subnets, a private access pattern for a storage account, policy assignments for location or tagging and a backup policy for a test virtual machine. The lab is valuable because it makes governance, networking, identity and resilience visible at the same time.

Another useful exercise is to write a short architecture decision record after each lab. The record should state the requirement, the options considered, the chosen design and the trade-off accepted. This habit mirrors the judgement AZ-305 tests and helps avoid a common preparation mistake: learning how to deploy resources without being able to explain why that deployment pattern is appropriate.

Exam-day expectations and common pitfalls

AZ-305 questions commonly test design reasoning through scenarios, multiple-response items and case-study style material. Candidates should expect to read carefully, identify constraints and distinguish between a technically possible answer and the answer that best satisfies the requirements. Time management matters because long scenarios can absorb attention before the actual decision point is clear.

A sensible exam approach is to read the requirement first, note constraints such as compliance, recovery objectives, existing hybrid dependencies or cost limits, then eliminate options that violate those constraints. Candidates should avoid looking for trick wording everywhere. The better habit is disciplined interpretation: answer what the scenario asks, not what a preferred design would be in a different organization.

The most common preparation pitfalls are predictable. Candidates memorize service capabilities but do not practise design trade-offs. They spend too little time on governance and cost management. They assume cloud-native patterns apply cleanly to every hybrid environment. They also neglect business continuity until late in the study plan, even though resilience decisions often affect storage, compute, networking and operations together.

Costs, renewal and keeping the credential useful

Exam fees vary by country and should be checked during registration. Lab costs also vary according to the resources used, which is why small environments, spending alerts and cleanup routines are part of responsible preparation. A candidate who can explain how to control practice costs is already thinking more like an architect.

Microsoft role-based certifications require ongoing renewal. The Azure Solutions Architect Expert credential can be renewed through a free renewal assessment on Microsoft Learn when eligible, and renewal should be treated as part of professional maintenance rather than an afterthought. Azure services, naming conventions and recommended patterns change, so renewal preparation is a useful forcing function for staying current.

After AZ-305, the next learning path should follow the work the architect actually does. Security-focused architects may benefit from deeper Azure security study such as AZ-500-aligned skills. Architects working heavily with analytics platforms may need stronger data engineering knowledge such as DP-203-aligned skills. Platform-oriented architects often gain more from DevOps, SRE, observability and infrastructure-as-code depth than from collecting unrelated credentials.

Turning AZ-305 preparation into architecture capability

The value of the Microsoft Certified: Azure Solutions Architect Expert credential depends on how preparation is approached. Candidates who connect AZ-305 objectives to landing zones, governance, resilience, hybrid design and cost control build skills that transfer directly into architecture discussions, design reviews and implementation planning.

A practical next step is to compare the official Microsoft Learn objectives with recent project experience, then design labs around the gaps. For candidates who prefer a guided format, Readynez can support AZ-305 preparation as part of a structured Microsoft learning path, but the enduring goal is the same in any study route: develop the judgement to choose Azure designs that fit real constraints.
