AZ-305 Practice Questions & Exam Prep — Designing Microsoft Azure Infrastructure Solutions

Get exam-ready for AZ-305 (Designing Microsoft Azure Infrastructure Solutions) — the single exam that earns the Microsoft Certified: Azure Solutions Architect Expert credential — on iPhone or iPad. Azure Mastery uses on-device AI to predict your readiness across all four design domains, surface case-study patterns, and target the topics most likely to trip you up.

The exam

What is the AZ-305 exam?

AZ-305 is the single exam required to earn the Microsoft Certified: Azure Solutions Architect Expert credential — Microsoft's senior architecture certification for the Azure platform. (The predecessor pair AZ-303 and AZ-304 were retired in March 2022 in favour of a single AZ-305 exam.) The Expert tier sits above the Associate-level AZ-104 and below specialty certs like Cybersecurity Architect (SC-100).

Unlike AZ-104, AZ-305 doesn't test your ability to configure Azure — it tests your ability to design solutions that satisfy a brief. You'll be given a multi-paragraph scenario (RTO/RPO targets, throughput requirements, compliance constraints, geographic spread) and asked which combination of Azure services best meets it.

The exam aligns to the Azure Well-Architected Framework and the Cloud Adoption Framework for Azure — the same patterns Microsoft expects architects to apply on the job.

Microsoft updated the AZ-305 skills outline on 17 April 2026. Every question in Azure Mastery's AZ-305 bank is mapped to the current outline — no leftover questions on retired services. Read the official outline at learn.microsoft.com.

AZ-305 exam objectives

Four design domains, with weights set by Microsoft's April 2026 update. Below, each domain's skill groups are lifted verbatim from Microsoft's official outline, so you can see precisely where a given topic is scored and where your gaps sit. AZ-305 questions test design judgement — picking the right Azure service for a given requirement — rather than configuration recall.

Aura presents a visual map of identity, compute, networking, and Azure operations skills.
Azure skill map

Design identity, governance, and monitoring solutionsPublished weight 25–30%

108 exam-scoped practice questions in the app

Explore Identity topics
  • Design solutions for logging and monitoring
  • Design authentication and authorization solutions
  • Design governance
  • Tests recommending an identity, governance, or monitoring design, not configuring any one Azure resource yourself.
  • Candidates apply an Azure-only control where the scenario actually needs an on-premises or hybrid authorisation tool.
  • Check whether the requirement covers Azure resources, on-premises resources, or both before naming a control.

Design data storage solutionsPublished weight 20–25%

86 exam-scoped practice questions in the app

Explore Storage topics
  • Design data storage solutions for relational data
  • Design data storage solutions for semi-structured and unstructured data
  • Design data integration
  • Clearing a stated RTO, RPO, or throughput number at the lowest cost is the judgement this domain checks.
  • The most feature-rich data service tends to win out over the one that simply meets the stated constraint.
  • Read the numeric requirement first; it usually rules out half the storage options immediately.

Design business continuity solutionsPublished weight 15–20%

80 exam-scoped practice questions in the app

Explore Continuity topics
  • Design solutions for backup and disaster recovery
  • Design for high availability
  • Tests telling a backup and disaster-recovery design apart from a high-availability design for the same workload.
  • Candidates treat backup and high availability as interchangeable even though they solve different problems.
  • Ask whether the scenario wants recovery after an outage or continuous uptime during one.

Design infrastructure solutionsPublished weight 30–35%

145 exam-scoped practice questions in the app

Explore Infra topics
  • Design compute solutions
  • Design an application architecture
  • Design migrations
  • Design network solutions
  • Compute, application-architecture, migration, and network choices all get weighed against a single stated business requirement.
  • A weak spot in one of the four infrastructure sub-areas shows up here first, since it's the largest domain.
  • Place migration and modernisation work inside the Cloud Adoption Framework's Adopt methodology, then distinguish the workload-onboarding activity the scenario describes.

Common traps

Where AZ-305 candidates slip

Four recurring misconceptions that trip up otherwise well-prepared AZ-305 candidates, grounded in the current skills outline.

"Cheapest" and "best" are not the same correct answer

AZ-305 stems name a constraint like an RTO or throughput figure and ask for the option that meets it at lowest cost.

  • The exam is testing whether you can stop at the option that clears the bar, not the most feature-complete one.
  • Read the numeric constraint first; it usually eliminates half the options before you weigh cost.

Backup and high availability solve different problems

A backup design answers how you recover after a loss, while a high-availability design answers how you avoid the outage itself.

  • The exam is testing whether you'd choose zone-redundant compute over a Recovery Services vault for continuous uptime.
  • Ask whether the scenario wants recovery after failure or continuity during it before naming a service.

The Cloud Adoption Framework separates methodologies from workload-onboarding activities

Strategy, Plan, Ready, Adopt, Govern, Secure, and Manage are the core methodologies. Migrate and Modernize are workload-onboarding approaches within Adopt, while assessment informs the plan.

  • First identify the methodology, then match the workload activity the scenario actually describes.
  • Do not treat assess, migrate, and modernise as peer phases in the framework.

Authorising Azure resources and on-premises resources use different tools

Azure RBAC authorises actions on Azure resources, while Conditional Access uses identity, device, location, and risk signals to grant or block access. Hybrid join and federation integrate identities; they are not substitute authorisation systems.

  • Separate identity integration, access-policy evaluation, and resource authorisation before choosing a control.
  • Check which resource and trust boundary the requirement names before answering.

Designed for AZ-305

How Azure Mastery helps you pass AZ-305

Exam-specific practice

  • 419 AZ-305 practice questions, each mapped to the 17 April 2026 outline across all four design domains.
  • Coverage follows identity and governance, storage, continuity, and infrastructure, tagged so weak spots surface fast.
  • Questions rehearse design judgement, picking the option that meets a stated constraint, the exam's actual style.

Predicted score

  • Exam IQ predicts your AZ-305 score on-device after roughly 30 questions, with a confidence range attached.
  • Infrastructure design carries nearly a third of the exam, so early predictions lean on how you handle it.
  • See exactly which domain, identity, storage, continuity, or infrastructure, is holding your score back.

Adaptive study plan

  • Miss a cost-versus-capability question and a similar design scenario returns in your next session.
  • Hold a domain steady across three sessions and the plan shifts weight to the next weak spot.
  • The plan targets the 700 pass score directly, not the number of questions you've answered.

Knowledge decay

  • AZ-305's four domains lean on shared judgement skills, so a forgotten pattern shows up across several of them.
  • A padlock icon flags a domain approaching decay before exam day catches you out.
  • Focus Weak Spots pulls from decayed domains first, ahead of anything new.

Exam rehearsal

  • Practise a full 100-minute session with flag-and-review switched off, matching the real Expert-tier clock.
  • The question mix follows the domain weights from the 17 April 2026 outline.
  • Every rehearsal question is original material written to the outline, not a copy of Microsoft's paper.

Answer Coach

  • Names the exact design trade-off behind a missed answer: cheapest versus most complete, backup versus high availability.
  • Explains why a Cloud Adoption Framework phase or an identity control was the wrong pick, and the rule to remember.
  • On supported devices, a note can be reworded locally, always validated against the authored answer first.

Aura guidance

  • Aura shifts focus toward whichever design domain is dragging as your first week of sessions plays out.
  • Each session ends with a plain-language recap of what improved and what to tackle next.

Private by design

  • Your AZ-305 answer history, readiness gauge, and Answer Coach notes never leave your device by default.
  • Architecture decisions stay confidential too: no Azure Mastery account or server ever sees your study data.
  • Turn iCloud sync on only if you want your notes backed up across devices.

Frequently asked

AZ-305 FAQs

Do I need AZ-104 before AZ-305?

Not to book it — Microsoft lets anyone sit AZ-305 directly. But the Solutions Architect Expert credential is only awarded once you also hold Azure Administrator Associate, earned through AZ-104. Pass AZ-305 first and you're just waiting on AZ-104 to unlock it. AZ-204 isn't an accepted alternative.

What does the AZ-305 exam format actually look like?

Microsoft's general guidance is 40–60 questions plus case studies, with formats varying by sitting. Azure Mastery's bank weights single-answer, scenario-based, and multi-select items heaviest, then adds case-study sets, drag-and-drop, and hotspot questions — all original practice content, not a copy of Microsoft's live item mix.

Why does AZ-305 feel harder than AZ-104 even with the same pass mark?

AZ-104 mostly checks whether you can configure a service; AZ-305 gives you a business constraint and asks which combination of services satisfies it, with rarely one "correct config" to recall. That judgement style takes longer to internalise, which is why AZ-305 has a higher first-attempt fail rate.

Which AZ-305 domain catches candidates most off guard?

Business continuity, despite being the smallest domain by weight. Candidates who've only configured single VMs or databases under-prepare for scenarios mixing backup, disaster recovery, and high-availability requirements across compute, relational data, and unstructured data at once.

What's the current AZ-305 exam voucher price?

The AZ-305 voucher is USD $165 in the United States, or around £128 in the UK — pricing varies by region. The Expert-tier certification it unlocks also needs annual renewal, free and online via Microsoft Learn.

Does the Solutions Architect Expert badge need renewing?

Yes. Expert certifications including Azure Solutions Architect Expert expire annually. Renewal is a free, short online assessment on Microsoft Learn within six months of your expiry date, targeting recent outline updates.

I didn't pass AZ-305 — how soon can I try again?

Not immediately, and each sitting needs its own voucher.

  • First retake: after 24 hours.
  • Second and third retakes: a 14-day wait each.
  • Cap: five attempts per rolling 12 months.
Realistically, how many weeks does AZ-305 prep take?

Plan eight to twelve weeks of focused study, even after passing AZ-104. AZ-305 tests judgement more than recall — you're given a scenario and asked which services satisfy it. Don't book until the readiness gauge holds around 730 or higher; AZ-305 is unforgiving of borderline scores.

Can I try Azure Mastery's AZ-305 content before paying?

Yes. The app is free to download, with a free allowance of AZ-305 questions so you can try every feature. The full bank of 419 AZ-305 practice questions unlocks with a one-time exam-pack purchase, or unlock every exam with a subscription or lifetime upgrade.
