About this exam

Exam AZ-305: Designing Microsoft Azure Infrastructure Solutions is the required exam for the Microsoft Certified: Azure Solutions Architect Expert certification. It targets architects who design cloud and hybrid solutions on Azure across compute, networking, storage, monitoring, and security, and who translate business requirements into designs aligned with the Azure Well-Architected Framework and the Cloud Adoption Framework for Azure. Candidates are expected to bring advanced experience in IT operations - networking, virtualization, identity, security, business continuity, disaster recovery, data platforms, and governance - plus hands-on experience with Azure administration, Azure development, and DevOps processes, because the role involves partnering with developers, administrators, security engineers, and data engineers. The exam measures four skill areas: design identity, governance, and monitoring solutions; design data storage solutions; design business continuity solutions; and design infrastructure solutions. The passing score is 700. The exam is offered in English, Japanese, Chinese (Simplified), Korean, German, French, Spanish, Portuguese (Brazil), Chinese (Traditional), and Italian, and has no retirement date. Preparation options include the self-paced study guide and practice assessments on Microsoft Learn and the instructor-led course Design Microsoft Azure Infrastructure Solutions. Note that the English version of the exam was updated on April 17, 2026, and localized versions follow roughly eight weeks later, so always confirm current objectives against the study guide before scheduling.

What you'll study

Common questions

About Azure AZ-305 preparation

What score do I need to pass AZ-305?

The passing score is 700. Microsoft reports scores on a scaled basis, so 700 is not a simple percentage of correct answers. Because question weighting varies, aim to be comfortable across every domain rather than maximizing raw correct answers in your strongest area.

What are the prerequisites for the Azure Solutions Architect Expert certification?

You must first earn the Microsoft Certified: Azure Administrator Associate certification; AZ-305 is the one required exam on top of it. Beyond the formal prerequisite, Microsoft recommends advanced experience with IT operations, Azure administration, Azure development, and DevOps processes before attempting the exam.

How is the exam structured, and how long does it take?

Microsoft does not publish the item count or duration on the exam page. Use the exam sandbox and the practice assessment linked from the exam page to see the interaction types (case studies, drag-and-drop, multiple choice) so the format itself is not a surprise on test day.

How much does the exam cost?

Pricing is based on the country or region in which the exam is proctored, so there is no single global figure. Microsoft notes that pricing excludes applicable taxes and is subject to change, and that you should confirm exact pricing with the exam provider before registering.

What happens if I fail - can I retake it?

Retake terms and waiting periods are governed by Microsoft's exam policies and FAQ rather than the exam overview page, so check those policies before scheduling a second attempt. Plan your first attempt as if it is the only one: work through the study guide objectives and practice assessments until you are consistently comfortable.

Does the certification expire?

Yes. Microsoft role-based certifications such as Azure Solutions Architect Expert must be renewed, but renewal is free: you pass an online assessment on Microsoft Learn to update your skills for the current job role. Keep an eye on the renewal window in your Learn profile so the credential does not lapse.

Which language versions are available, and does the update timing matter?

The exam is available in English, Japanese, Chinese (Simplified), Korean, German, French, Spanish, Portuguese (Brazil), Chinese (Traditional), and Italian. The English version was updated on April 17, 2026, and localized versions are typically updated about eight weeks later, so a localized exam may briefly measure older objectives.

In what order should I study the four domains?

Follow the study guide's weighting rather than studying alphabetically. Design infrastructure solutions carries the largest share (30–35%), followed by identity, governance, and monitoring (25–30%), data storage (20–25%), and business continuity (15–20%). Start with your weakest high-weight area, and use the instructor-led Design Microsoft Azure Infrastructure Solutions course if you prefer structured delivery.

What are the most common reasons candidates struggle?

Two patterns dominate: treating it as an administration exam (memorizing portal steps instead of justifying a design trade-off), and skimming the case studies before reading the requirements. Practice stating why one service satisfies a stated constraint better than another, and rehearse mapping requirements to Well-Architected Framework pillars before answering.
