What AZ-305 Certification Actually Is
AZ-305 is Microsoft's exam for the Microsoft Certified: Azure Solutions Architect Expert credential. Formally titled "Designing Microsoft Azure Infrastructure Solutions," it tests whether you can translate business and technical requirements into architecture decisions across compute, storage, networking, identity, governance, and disaster recovery on Azure. It is not an entry-level exam. Microsoft governs the exam directly, and it is delivered through Pearson VUE - either at a physical test center or via online proctoring from your own machine.
Unlike associate-level exams that focus on how to configure or deploy a specific service, AZ-305 focuses on how to choose between options when there is no single correct answer. You'll be asked to weigh trade-offs: which storage tier fits a cost constraint, which identity model satisfies a compliance requirement, which region pairing meets a recovery time objective. If you want a deeper walkthrough of what this credential means for your resume and career trajectory, see our companion piece on AZ-305 Certification and the more concise What Is AZ-305? overview.
Prerequisites and Certification Path
To earn Microsoft Certified: Azure Solutions Architect Expert, you need two things: a passing AZ-305 score and an active Azure Administrator Associate certification. Microsoft doesn't enforce this as a technical exam prerequisite (you can technically register and sit AZ-305 without holding the Associate cert), but you won't receive the Expert-level credential until both boxes are checked.
Practically, this means candidates are expected to already have advanced, hands-on experience with Azure administration, networking, virtualization, identity, security, business continuity and disaster recovery, data platform services, governance, and general development/DevOps practices. This exam assumes you've been working in Azure environments, not studying them from scratch. If your background is thinner in one of these areas - say, data platform design or DevOps pipelines - plan extra review time there before exam day.

Exam Format, Registration, and Fees
AZ-305 pricing is region-dependent. In the United States, the standard fee is $165 USD plus applicable taxes, with no separate member/non-member pricing tier. You register and schedule through Pearson VUE, choosing between an in-person test center or online proctoring from home or office.
The exam itself does not have a fixed published question count, though Microsoft notes most certification exams fall in the 40-60 question range. What is documented: exams like AZ-305 that don't include labs give you 100 minutes of exam time within a 120-minute seat time (the extra minutes cover the NDA, tutorial, and survey). Microsoft doesn't pre-announce whether a given exam includes labs, so budget your pacing conservatively.
Format-wise, expect a mix pulled from Microsoft's standard exam sandbox: active screen questions, build-list, case studies, drag-and-drop, hot area, and traditional multiple choice. Case studies in particular are a hallmark of AZ-305 - you'll read a scenario with business requirements, technical constraints, and existing infrastructure, then answer several questions that all reference that same scenario. Some associate/expert exams, including this one, also grant limited access to Microsoft Learn documentation during the test while the clock keeps running, so knowing where to find reference material fast can save you time.
Key Takeaway
Because Microsoft Learn access is available mid-exam, practice navigating Azure documentation quickly during your prep - don't rely on memorizing every setting, but do know exactly where to look.
A passing score is 700 or higher (on Microsoft's standard 1-1000 scale). Microsoft does not publish official pass rate statistics, so treat any specific percentage you see elsewhere with skepticism.

The Four AZ-305 Exam Domains
Microsoft organizes AZ-305 into four skills-measured domains, each with its own weight on the exam. Understanding these weights should directly shape how you allocate study time - spending equal hours on all four is a common, avoidable mistake.
Domain 1: Design identity, governance, and monitoring solutions (25-30%)
Covers designing for Azure AD (Entra ID), RBAC, governance structures like management groups and policies, and monitoring/alerting strategy.
- Hybrid identity and conditional access design decisions
- Azure Policy, blueprints, and management group hierarchies
- Logging, alerting, and Azure Monitor architecture choices
Domain 2: Design data storage solutions (20-25%)
Focuses on choosing the right storage and database services for relational, non-relational, and big data workloads.
- Selecting between Azure SQL, Cosmos DB, and storage account tiers
- Data redundancy and replication design
- Data integration and analytics platform selection
Domain 3: Design business continuity solutions (15-20%)
Tests disaster recovery, backup, and high-availability architecture across compute, data, and hybrid workloads.
- Recovery Time Objective and Recovery Point Objective trade-offs
- Azure Backup and Site Recovery design scenarios
- High-availability patterns for VMs, databases, and applications
Domain 4: Design infrastructure solutions (30-35%)
The largest domain by weight, spanning compute selection, application architecture, networking design, and migration planning.
- Choosing between VMs, containers, and serverless compute
- Virtual network topology, hybrid connectivity, and load balancing
- Migration strategy for on-premises to Azure workloads
For domain-by-domain deep dives with study checklists, see AZ-305 Domain 1, AZ-305 Domain 2, AZ-305 Domain 3, and AZ-305 Domain 4. A consolidated view of how all four fit together is in AZ-305 Exam Domains 2026: Complete Guide to All 4 Content Areas.
| Domain | Weight | Primary Focus |
|---|---|---|
| Design infrastructure solutions | 30-35% | Compute, networking, app architecture, migration |
| Design identity, governance, and monitoring | 25-30% | Identity, RBAC, policy, monitoring |
| Design data storage solutions | 20-25% | Relational/non-relational data, analytics |
| Design business continuity solutions | 15-20% | Backup, DR, high availability |
Who Hires AZ-305-Certified Architects
Because AZ-305 sits at the architect level and requires the Azure Administrator Associate as a companion credential, it typically shows up in job postings for roles like cloud solutions architect, Azure infrastructure architect, senior cloud engineer, and platform architect. These roles usually require multi-year Azure experience and expect the candidate to own architecture decisions rather than just implement someone else's design - consistent with the exam's emphasis on trade-off analysis over configuration steps.
Organizations migrating substantial workloads to Azure, managed service providers running multi-tenant Azure environments, and enterprises with hybrid or multi-region requirements are the most common employers seeking this credential specifically.

How to Prepare Without Wasting Time
Given that Domain 4 (infrastructure) and Domain 1 (identity/governance) together make up well over half the exam, a study schedule that treats every domain equally is inefficient. A more realistic allocation front-loads infrastructure and identity design, then narrows into data storage and business continuity in the final stretch, since those domains carry lower individual weight but still require scenario-based reasoning.
Design Infrastructure Solutions (Domain 4)
- Compare compute options: VMs, AKS, App Service, Functions
- Practice VNet, peering, and hybrid connectivity scenarios
- Work through migration case studies end to end
Design Identity, Governance, and Monitoring (Domain 1)
- Map out RBAC vs. Azure Policy use cases
- Review conditional access and hybrid identity patterns
- Study Azure Monitor and Log Analytics design choices
Data Storage and Business Continuity (Domains 2 & 3)
- Drill storage tier and database selection scenarios
- Study RTO/RPO math and backup architecture
- Run full-length practice case studies under timed conditions
Whatever schedule you follow, spend the last week almost entirely on scenario-based practice questions rather than passive reading - AZ-305's case study format rewards pattern recognition more than raw fact recall. For a more detailed week-by-week plan with resource recommendations, see AZ-305 Study Guide 2026: How to Pass on Your First Attempt. If you're still gauging how difficult the exam is relative to other Azure certifications, How Hard Is the AZ-305 Exam? Complete Difficulty Guide 2026 breaks that down further. You can also run through realistic scenario questions on our AZ-305 practice test platform to see where your domain knowledge actually stands before booking the real exam.
Passing Score, Validity, and Renewal
A raw score of 700 or above (out of 1000) is required to pass. Microsoft does not publish pass rate figures for AZ-305 or any of its exams, so any specific percentage circulating online is unofficial.
Once earned, Microsoft Certified: Azure Solutions Architect Expert is valid for 12 months. Renewal is free and handled entirely online - you complete a renewal assessment through Microsoft Learn during the eligible renewal window, with no need to retake the full proctored AZ-305 exam. As of this writing, the English exam and its study guide were last updated for skills measured as of April 17, 2026, and Microsoft has not listed a retirement date, meaning the credential and its content should stay stable for the near term.
