Designing Microsoft Azure Infrastructure Solutions: AZ-305 Exam Guide
AZ-305 validates an Azure solutions architect’s ability to turn business and technical requirements into cloud or hybrid designs covering identity, governance, monitoring, data, continuity, and infrastructure. It is aimed at experienced IT professionals who already understand Azure administration, development, and DevOps practices. This guide helps you decide whether your current foundation is strong enough to schedule the exam, which skill areas deserve the most study time, and how to prepare through design reasoning rather than product-name memorization.
What does AZ-305 validate?
AZ-305 validates the design decisions expected from an Azure solutions architect, not simply the ability to deploy isolated resources. Microsoft describes the role as designing cloud and hybrid solutions involving compute, network, storage, monitoring, and security, while translating stakeholder requirements into designs aligned with the Azure Well-Architected Framework and Cloud Adoption Framework for Azure.
The role also requires collaboration with developers, administrators, security engineers, and data engineers. That context matters when studying: a strong answer must account for how architecture choices affect operations, security, cost, reliability, performance, and future change. Treat each topic as part of an interconnected solution rather than as a separate Azure service catalogue.
The certification page identifies AZ-305 as a required exam for Microsoft Certified: Azure Solutions Architect Expert. The certification also requires the Microsoft Certified: Azure Administrator Associate certification. If you do not hold that prerequisite, include it in your certification plan before treating AZ-305 as the final step.

Who should prepare for this exam?
AZ-305 is best suited to practitioners who can already reason about enterprise IT operations and Azure architecture. Microsoft expects advanced knowledge of networking, virtualization, identity, security, business continuity, disaster recovery, data platforms, and governance, plus experience with Azure administration, Azure development, and DevOps processes.
The official instructor-led course gives a similar starting point. Before attending, learners are expected to have deployed or administered Azure resources and to understand Azure compute technologies such as virtual machines, containers, and serverless solutions; Azure virtual networking including load balancers; Azure Storage technologies; messaging; and high availability.
Use this readiness test before buying a course or booking an appointment. Can you explain why one architecture is preferable to another when requirements conflict? Can you trace identity, network, data, recovery, and monitoring consequences across a design? If your answer is usually a service definition rather than a trade-off, strengthen the foundation first.
Microsoft classifies the associated course as Advanced and associates it with the Solution Architect role. Those labels are useful signals about the intended level, but they are not substitutes for reviewing the current skills measured. Source: https://learn.microsoft.com/en-us/training/courses/AZ-305T00
Which skills carry the most weight?
The current AZ-305 skills measured are Design identity, governance, and monitoring solutions (25–30%), Design data storage solutions (20–25%), Design business continuity solutions (15–20%), and Design infrastructure solutions (30–35%). Give the largest study block to Design infrastructure solutions (30–35%) and then cover the other domains systematically rather than ignoring the smaller business continuity area.
Design identity, governance, and monitoring solutions (25–30%) includes the control plane and operational visibility around a solution. Study authentication and authorization, governance decisions, policy and resource organization, and logging and monitoring design as connected concerns. Your notes should explain how a design controls access, enforces standards, detects issues, and supports investigation.
Design data storage solutions (20–25%) requires more than choosing a database or storage account. Practise mapping data characteristics and application needs to an appropriate storage design, then examine access, availability, performance, protection, and integration consequences. Write down the requirement that drives each choice so that you can recognize the same decision in a different scenario.
Design business continuity solutions (15–20%) deserves deliberate preparation even though it is the smallest measured range. Work through availability, backup, disaster recovery, and recovery objectives as design problems. Distinguish protection against data loss from restoration of service, and connect each proposed control to the failure it is intended to address.
Design infrastructure solutions (30–35%) covers the broadest architecture surface. The related Microsoft learning path focuses on compute, application architecture, networking, and migrations. Review those areas together: a migration choice affects network connectivity, application dependencies, identity, data movement, operations, and the target platform.
The Exam Readiness Zone video presents a different set of figures: Design identity, governance, and monitoring solutions (26%), Design data storage solutions (24%), Design business continuity solutions (17%), and Design infrastructure solutions (33%). Because the official study guide and exam page identify the current ranges as of April 17, 2026, use those pages to plan your preparation and use the video for topic orientation rather than treating its figures as the current blueprint.

How should you study identity, governance, and monitoring?
Start this domain with an access-and-control map. For each scenario, identify who or what needs access, the scope of that access, the authentication boundary, the authorization decision, the governance control, and the evidence that operators need. This sequence prevents a common mistake: selecting an identity feature without explaining how it supports the wider operating model.
Use Microsoft’s identity, governance, and monitoring learning path as a structured foundation. It contains modules on designing governance, authentication and authorization solutions, and logging and monitoring for Azure resources. Study each module by converting its concepts into short decision statements, such as which requirement would make a particular governance or monitoring approach unsuitable.
A useful exercise is to create a one-page design for a multi-team Azure environment. Mark ownership boundaries, permitted resource patterns, access responsibilities, policy intent, and monitoring destinations. Then challenge the design with a new team, a compliance requirement, or an operational incident. If the design cannot absorb that change cleanly, revisit its assumptions.
Do not study monitoring as an afterthought. A design that is secure but cannot reveal failed operations, access anomalies, or service degradation is incomplete. Likewise, governance should not be reduced to a list of controls; practise explaining who applies each control, what it protects, and how exceptions would be managed.

How should you study data storage and application architecture?
Approach storage questions by classifying the workload before considering a product. Identify data shape, access pattern, consistency needs, scale characteristics, latency expectations, integration requirements, retention, and recovery needs. Then compare candidate designs against those constraints. This approach is more reliable than memorizing isolated service features because scenario wording may change while the underlying design principle remains.
The infrastructure learning path contains a module on application architecture alongside modules on compute, networking, and migrations. Use that order intentionally: application boundaries and communication patterns influence compute placement, network design, scaling, observability, and migration sequencing. Review messaging and high availability concepts because Microsoft lists them among the conceptual knowledge expected for the associated course.
Build comparison tables for the storage decisions you find hardest. Keep the columns focused on requirements and consequences: workload pattern, durability or availability need, access model, operational responsibility, integration, and migration implications. Do not copy a service description without adding a “why this design” sentence. That sentence is the part you need to retrieve under pressure.
A common pitfall is choosing the most familiar storage option for every workload. Another is treating data migration as a later implementation detail. For each design, ask how data reaches the target, how the application behaves during transition, what must be protected, and how the chosen storage model affects recovery and monitoring.

How should you study business continuity?
Prepare business continuity as a requirements-matching exercise. Separate service availability, backup, disaster recovery, and data protection, then connect each one to business impact. A design is credible only when its recovery approach matches the required service behavior and acceptable data loss; a backup copy alone does not automatically provide a complete continuity strategy.
Create failure scenarios rather than reading continuity features in isolation. Consider a failed component, unavailable region, corrupted data, an application dependency outage, and an operator error. For each case, record the detection mechanism, the protected asset, the recovery action, the expected dependency order, and the validation step. This exposes gaps that product-by-product revision often misses.
Link continuity to the other blueprint domains. Identity must remain usable during recovery, network paths must support the restored workload, data replication must suit the workload, and monitoring must show whether recovery succeeded. When reviewing an answer, ask which assumption makes the proposed recovery possible and whether the scenario actually supplies that assumption.
Avoid a frequent exam-preparation error: confusing redundancy with recovery. Multiple instances may address a component failure, while a separate recovery design may be needed for regional disruption or data corruption. Your notes should state the threat being addressed and the limitation of the chosen control.
How should you study infrastructure, networking, and migrations?
Study infrastructure as an architecture chain: workload requirements, compute model, application shape, network topology, dependencies, migration approach, and operational controls. The official infrastructure path has four modules covering Azure compute, application architecture, network solutions, and migrations, making it a useful backbone for this domain.
For compute, compare virtual machines, containers, and serverless approaches by operational responsibility, workload fit, scaling behavior, integration, and migration effort. For networking, draw the traffic paths rather than memorizing component names. Include application entry points, segmentation, private or hybrid connectivity assumptions, load distribution, dependencies, and monitoring points.
For migration scenarios, begin with the existing estate and its constraints. Identify what can change, what must remain compatible, the order in which dependencies move, and how data synchronization or rollback would work. Then choose a target architecture. A migration answer that ignores the starting environment is usually incomplete even when the destination service sounds appropriate.
Use diagrams sparingly but deliberately. One page should show trust boundaries and traffic; another should show data movement and recovery; a third should show deployment and operational ownership. Explain each diagram aloud in requirement-to-decision language. This practice reveals whether you understand architecture or have only assembled a collection of Azure icons.
The official path states that learners should have conceptual knowledge of compute, application, networking, and migration solutions and working experience architecting compute and network solutions. If those prerequisites describe gaps in your background, add hands-on architecture exercises before moving to timed assessment practice.
What study sequence works best?
Use a four-stage sequence: establish the blueprint, close foundation gaps, practise integrated designs, and verify readiness. Start with the current Microsoft study guide, not an old outline or a third-party topic list. Mark each bullet as confident, familiar, or unknown, then allocate study time according to both the official domain range and your actual weakness.
Stage one is an inventory session. Read the audience profile and every current skills-measured heading. Create a grid with the four domains, the relevant Microsoft Learn resources, and a column for decisions you cannot yet explain. This turns preparation into a finite diagnostic task and helps prevent spending all your time on the Azure services you already use at work.
Stage two is targeted learning. Complete the four-module infrastructure learning path for compute, applications, networking, and migrations. Pair it with the three-module identity, governance, and monitoring path. Use the instructor-led course outline as a checklist for governance, compute, application architecture, storage, data integration, authentication, networks, business continuity, and migrations, whether or not you attend the course.
Stage three is design practice. Take a business requirement and produce a concise architecture decision record. State the requirement, candidate options, selected design, rejected alternative, security and governance implications, continuity approach, and operational evidence. Repeat with a different workload shape. The objective is to practise transfer, not to recreate remembered questions.
Stage four is verification. Use Microsoft’s free practice assessment and the exam sandbox from the official exam resources. Review every uncertain answer by returning to the relevant skill objective and documentation. Do not treat a practice result as proof that you have mastered the exam; use it to identify reasoning gaps and topics needing another design exercise.

What should a practical roadmap look like?
A practical roadmap should end each study session with an observable output: a completed module, a service comparison, a diagram, a design decision record, or a reviewed practice assessment. Schedule the exam only after you can explain choices across all four domains and have checked the current study guide for updates. The calendar length should reflect your baseline rather than an arbitrary promise.
Begin with the infrastructure path’s four modules: compute, application architecture, network solutions, and migrations. Microsoft states that this learning path contains four modules, takes approximately 3 hours 39 minutes, and covers compute, applications, networking, and migrations. Treat that stated learning-path time as course orientation, not as a complete estimate for becoming exam-ready.
Next, complete the identity, governance, and monitoring path and create a matching decision map. Then study data storage and business continuity through scenario notes. At this point, revisit the official blueprint and deliberately rebalance your time. A candidate who is strong in networking but weak in recovery should not continue polishing networking diagrams simply because that work feels easier.
Finish with integrated case exercises. For each one, begin with stakeholder goals and constraints, then design identity, governance, monitoring, storage, continuity, compute, network, and migration components. Review the result against the Well-Architected and Cloud Adoption perspectives named by Microsoft. Record the trade-offs you made and the information that would change your design.

Which preparation mistakes reduce readiness?
The most damaging mistake is studying an outdated blueprint. Microsoft says the English-language version was updated on April 17, 2026 and directs candidates to the study guide for recent changes. Check the current study guide immediately before final revision, especially if your notes, course, or video was produced before that update.
Do not confuse recognition with design competence. Being able to define a service is different from knowing when it fits, what requirement it satisfies, what it depends on, and what trade-off it creates. Replace flashcards that ask only “What is this service?” with prompts asking “Which requirement rules this option in or out?”
Do not distribute study time equally without a reason. The official ranges differ by domain, and your personal gaps may differ further. Use the current domain labels with their percentages when planning, then add extra work where you repeatedly make incorrect or poorly justified decisions.
Avoid relying on unauthorized question collections or memorization of supposed live items. They cannot establish whether you understand the architecture, may be inaccurate or outdated, and do not replace the official study guide or hands-on reasoning. Prepare from published skills and legitimate learning resources instead.
Finally, do not ignore language and account planning. Confirm the available language on the official scheduling information, and use a personal Microsoft account when registering because Microsoft warns that exam records tied to an organizational account can be lost and unrecoverable if you leave the organization.
What exam and scheduling details are officially confirmed?
AZ-305 has a passing score of 700. Microsoft lists the exam in English, Japanese, Chinese (Simplified), Korean, German, French, Spanish, Portuguese (Brazil), Chinese (Traditional), and Italian. Confirm the current language and appointment information on the official exam page before scheduling because Microsoft updates the English version first and localized versions may follow later.
Microsoft states that a localized version, when available, is updated approximately eight weeks after the English-language update, while also warning that this timing is not guaranteed in every case. If the exam is not available in your preferred language, the study guide says you can request an additional 30 minutes to complete the exam.
The official exam page lists AZ-305 as having no retirement date. That status can change as Microsoft reviews certifications and exam content, so check the live page rather than relying on an old article or booking assumption. Microsoft’s retirement guidance says candidates preparing for an exam scheduled for retirement should take it before the stated retirement date.
The exam price is based on the country or region where the exam is proctored. Confirm the exact amount with the exam provider before registering. The supplied official material does not establish a delivery method or a universal appointment duration, so verify those details during the scheduling process instead of assuming they apply to every candidate.
For scheduling and account management, connect your certification profile to Microsoft Learn and use a personal Microsoft account as Microsoft recommends. Review accommodation options through the official study-guide resources if you require assistive devices, extra time, or another modification to the exam experience.

What should you do next?
Your next action is to open the current AZ-305 study guide, verify the skills measured as of April 17, 2026, and rate yourself against each domain. Then choose a preparation route that fits your career goals, desired skillset, and schedule: self-paced study, instructor-led training, or a combination. Microsoft presents both self-paced and instructor-led preparation options.
If the diagnostic shows strong Azure administration but weak architecture trade-offs, prioritise integrated design exercises. If networking or compute fundamentals are missing, work through the infrastructure learning path before using practice assessments. If identity, governance, storage, or continuity is the weak point, build focused decision maps and test them against cross-domain scenarios.
After each practice session, write down three things: the requirement you missed, the design assumption you overlooked, and the source you will use to correct it. Schedule only when your review demonstrates consistent reasoning across the blueprint and you have checked the official page for the latest language, scoring, and update information.
AZ-305 rewards structured architectural judgment. A preparation plan built around requirements, constraints, dependencies, and consequences gives you a more durable way to approach unfamiliar scenarios than a list of remembered product descriptions.
Conclusion
Use the official blueprint as the boundary of your preparation, then practise the work behind it: translating requirements into defensible Azure and hybrid designs. Confirm the prerequisite certification, review the April 17, 2026 study-guide update, select resources that match your gaps, and verify scheduling details on Microsoft Learn. The strongest final review is not another service list; it is a set of clear architecture decisions that connect identity, governance, data, continuity, infrastructure, and operations.
