Microsoft Certified: Azure Solutions Architect Expert Practice Tests

What to Expect

The Microsoft Certified: Azure Solutions Architect Expert exam costs $165 USD You'll face 50 questions in 120 minutes, giving you roughly 2 minutes and 24 seconds per question. 0 to 1000 scale, passing at 700. Case study sections are weighted and scored as a block, so doing poorly on one case study can hurt more than missing a few standalone questions.

Prerequisites and Audience

You need AZ-104 (Azure Administrator Associate) to earn the full Azure Solutions Architect Expert credential — AZ-305 alone just gives you the design exam. And honestly, don't even attempt AZ-305 without solid AZ-104 knowledge. The architecture exam assumes you already know how Azure services work. If you can't explain VNet peering or NSG rules off the top of your head, start with AZ-104 first. Solutions architects who design cloud and hybrid solutions on Azure. This isn't for people just learning Azure — it's for those who've already been building things and need to prove they can design at an architectural level. If your job involves making decisions about which Azure services to use and how they fit together, this is your cert.

Staying Certified

Valid for one year — yes, Microsoft certs expire faster than AWS or GCP. The good news is renewal is completely free. Six months before expiry, you get access to an untimed, open-book renewal assessment on Microsoft Learn. It's honestly pretty painless compared to retaking the full exam.

Recent Changes

AZ-305 replaced the old AZ-303/AZ-304 combo, consolidating two exams into one. The current version puts more emphasis on Azure Arc for hybrid scenarios, Bicep templates for IaC, and Microsoft Entra ID (which is what they're calling Azure AD now — get used to the new name because the exam uses it). Case studies remain a distinctive element that other cloud exams don't really have.

The exam tests your ability to design solutions across identity and governance, data storage, business continuity and DR, and infrastructure. Here's the thing that makes AZ-305 unique: the case study sections. You'll get a complex business scenario spread across multiple tabs of information, answer several questions about it, and once you move on, you can't go back. You need to design solutions, not just pick services from a menu.

Design Infrastructure Solutions

Design Infrastructure Solutions carries 32% of the exam weight, making it the single most impactful domain. Allocate your study time accordingly and make sure you can answer questions on this topic confidently before sitting the exam.

Design Identity, Governance, and Monitoring Solutions

Design Identity, Governance, and Monitoring Solutions carries 28% of the exam weight, making it the single most impactful domain. Allocate your study time accordingly and make sure you can answer questions on this topic confidently before sitting the exam.

Design Data Storage Solutions

Design Data Storage Solutions at 22% is a substantial portion of the exam. You can't afford to be weak here. Focus on understanding the core concepts and common scenario patterns.

Design Business Continuity Solutions

Design Business Continuity Solutions at 18% is a substantial portion of the exam. You can't afford to be weak here. Focus on understanding the core concepts and common scenario patterns.

Question Format

Multiple-choice, multiple-response, drag-and-drop, and case studies. The case studies are the big differentiator — they present a business scenario with tabs for requirements, existing infrastructure, and constraints. You answer several questions based on that scenario, and you can't return once you leave. Read every tab carefully before answering anything.

Study Timeline

Two to three months if you already have AZ-104 locked in. If you're studying for both exams at the same time, plan for four to five months total. AZ-305 requires synthesis — understanding how different Azure services work together to solve business problems. You can't just memorize service features.

Top Resources

Microsoft Learn's AZ-305 learning path is genuinely good and free. The Azure Architecture Center has reference architectures that mirror exam scenarios. The official practice assessment on Microsoft Learn gives you a feel for the question style. And don't skip the Azure Well-Architected Framework — it's the design philosophy behind many exam questions.

Common Mistakes

Jumping into AZ-305 without solid AZ-104 foundations. The architecture exam doesn't explain what an NSG does — it expects you to know and asks you to decide which type of load balancing to put in front of a multi-region app. The other big mistake is rushing through case study tabs. People skim the requirements and miss critical constraints that change the correct answer.

Hands-On Advice

Build a multi-region application: Front Door for global load balancing, App Service for compute, SQL Database with geo-replication, Key Vault for secrets management. Add Azure Monitor and a Log Analytics workspace for observability. Deploy the whole thing with Bicep templates. If you can design, deploy, and explain that architecture, you're in good shape for the exam.

Testing Options

Pearson VUE testing centers or online proctoring. Either works. Just be aware that the case study format means you'll be doing a lot of tab-switching and reading, which some people find easier on a larger screen at a testing center.

Time Management

About 50 questions in 100 minutes. That seems fine until you hit the case studies, which eat up time because you're reading extensive background material across multiple tabs. My advice: do the case studies when they appear and do them carefully — you can't go back. The standalone questions afterward tend to go faster.

How Hard Is This Exam?

On a scale of 1 to 10, AZ-305 is about a 7.5. It's the Expert-level Azure cert, and it plays like one. The difficulty comes from two things: the case study format (you can't go back once you finish a case study section) and the fact that it tests design judgment, not just service knowledge. You need to explain why you'd choose Cosmos DB over SQL Database for a specific workload, not just know that both exist. The topics that trip people up most are hybrid scenarios with Azure Arc, business continuity design with RPO/RTO requirements, and identity architecture with Microsoft Entra ID. If you don't have solid AZ-104 foundations, the design questions will feel impossible because you won't understand the building blocks well enough to evaluate trade-offs.

Pass Rate Data

Microsoft doesn't publish pass rates, but community estimates suggest around 50-60% first-attempt pass rate. Candidates who have real-world Azure architecture experience and strong AZ-104 foundations do significantly better. If you're scoring above 80% on practice tests, you're in good shape. The case study sections can swing your score significantly — a bad case study performance can tank an otherwise passing score.

Each Pruvos practice test mirrors the AZ-305 format: 50 questions with a 120-minute timer, distributed across four domains — Design Infrastructure Solutions (32%), Design Identity, Governance, and Monitoring Solutions (28%), Design Data Storage Solutions (22%), and Design Business Continuity Solutions (18%). We have 6 full practice tests with 300 unique questions. The case-study style questions in Pruvos tests help you practice the same kind of multi-tab scenario analysis the real exam uses. Focus on Infrastructure Solutions first since it's the heaviest domain at 32%. Track your domain scores across tests to see consistent improvement before booking the real exam.

Practice tests are the single most effective study tool for the AZ-305 exam. They reveal your weak domains before the real exam does, and getting questions wrong in practice is how you learn. Each practice test here mirrors the real exam format: 50 questions, timed at 120 minutes, with the same 4-domain distribution.

Don't just take practice tests and check your score. Review every wrong answer and understand why the correct option is better. For the AZ-305, pay special attention to Design Infrastructure Solutions (32%) and Design Identity, Governance, and Monitoring Solutions (28%) questions since they carry the most weight.
