This guide covers the latest exam objectives, certification requirements, exam format, and a practical study plan to help you prepare.
What is the Azure Solutions Architect Expert certification?
The Microsoft Certified: Azure Solutions Architect Expert certification validates your ability to design cloud and hybrid solutions running on Azure.
To earn it, you must:
- Hold an active Microsoft Certified: Azure Administrator Associate certification, typically earned by passing AZ-104. This exam emphasizes implementing and managing Azure resources.
- Pass AZ-305: Designing Microsoft Azure Infrastructure Solutions. This exam focuses on designing solutions and recommending the best services for specific requirements.
You can take AZ-305 before AZ-104, but Microsoft will not award the expert certification until you meet both requirements.1
Microsoft expects AZ-305 candidates to have advanced knowledge of networking, virtualization, security, identity, business continuity, data platforms, and governance, along with experience in Azure administration, development, and DevOps.

What topics are covered on AZ-305?
According to Microsoft’s April 2026 study guide, the exam includes four domains.2
| Skills measured | Exam weight |
| Design identity, governance, and monitoring solutions | 25–30% |
| Design data storage solutions | 20–25% |
| Design business continuity solutions | 15–20% |
| Design infrastructure solutions | 30–35% |
Let’s look at what you should know about each area.
1. Design identity, governance, and monitoring solutions (25–30%)
Identity and security are essential to any Azure architecture. You should understand Microsoft Entra ID (formerly Azure Active Directory), including authentication, authorization, identity management, and securing access to cloud and on-premises resources.
Focus on designing solutions for:
- Authentication and role-based access control.
- Identity governance and access management.
- Secrets, certificates, and key management.
- Azure management groups, subscriptions, and resource groups.
- Compliance, logging, and monitoring.
You should also understand how Azure Monitor and related monitoring services help organizations detect problems and maintain operational visibility.
The key is knowing when and why to recommend a particular solution, rather than simply memorizing configuration steps.
2. Design data storage solutions (20–25%)
Azure offers multiple ways to store and process data. As an architect, you must determine which approach best fits the workload. Prepare to compare relational databases such as Azure SQL Database with non-relational services such as Azure Cosmos DB.
You should also understand Azure Storage options for structured, semi-structured, and unstructured data.
Important considerations include:
- Data consistency and scalability.
- Performance and service tiers.
- Storage durability and protection.
- Backup and recovery requirements.
- Data integration and analytics.
- Cost and operational complexity.
For example, when would you recommend a relational database instead of a globally distributed NoSQL database? These decisions depend on application requirements, data relationships, expected traffic, and acceptable trade-offs.
3. Design business continuity solutions (15–20%)
Business continuity is about keeping services available and recovering when something goes wrong. You should understand two important concepts:
- Recovery Time Objective (RTO): How quickly a service must be restored after an outage.
- Recovery Point Objective (RPO): How much data loss, measured in time, the business can tolerate.
Prepare to recommend backup, disaster recovery, and high-availability solutions for compute, databases, and storage.
Understand the differences between availability zones, regional redundancy, and recovery strategies. For example, a business-critical application may require rapid recovery and minimal data loss, while a less critical workload may prioritize lower costs.
An architect must balance these requirements with the organization’s budget and operational capabilities.
4. Design infrastructure solutions (30–35%)
Infrastructure is the largest AZ-305 domain, so we recommend dedicating a substantial part of your study time to it. You will need to evaluate compute, networking, application architecture, and migration options.
Compute and application architecture
Understand when to recommend:
- Azure Virtual Machines.
- Azure App Service.
- Container-based solutions.
- Serverless computing.
- Messaging and event-driven architectures.
- API integration, caching, and automated deployments.
For example, why choose a VM instead of App Service? A VM offers greater operating-system control, while App Service reduces infrastructure management for supported web applications.
Neither is universally better. The correct recommendation depends on the workload.
Networking and migrations
You should also understand Azure networking approaches, including virtual network peering, VPN Gateway, ExpressRoute, and Azure Virtual WAN.
Evaluate connectivity, security, cost, performance, and operational requirements.
For migrations, learn how to assess existing applications and recommend suitable Azure infrastructure-as-a-service or platform-as-a-service solutions.
Microsoft’s Azure Well-Architected Framework and Cloud Adoption Framework are valuable study resources because they connect technical decisions to reliability, security, cost, operations, and business strategy.
How to pass AZ-305: A step-by-step study plan
Even experienced Azure professionals should prepare specifically for this exam. We recommend preparing approximately four to six weeks if you’re already comfortable working in Azure. If you’re newer to cloud architecture, you may need considerably longer.
Step 1: Review the latest objectives
Start with Microsoft’s official AZ-305 study guide. Check the current skills-measured date and compare the objectives against what you already know. Microsoft updates certification exams periodically, so older courses and practice questions may not cover everything.
Step 2: Strengthen your Azure foundations
If you haven’t earned AZ-104 yet, consider preparing for it first. Its administrative foundations will help you understand how Azure services behave in real environments.
If you’re completely new to Azure, AZ-900 is a useful starting point.
Step 3: Enroll in a structured AZ-305 course
A structured course helps you follow a clear learning path, stay focused on exam objectives, and reinforce concepts through practical demonstrations rather than studying Azure services in isolation.
The AZ-305: Microsoft Azure Solutions Architect Expert course on Udemy covers key exam topics, including identity and governance, monitoring, data storage, backup and disaster recovery, high availability, networking, compute, and application architecture.
Recommended Udemy course
With guided lessons and hands-on demonstrations, you can build the technical knowledge and design judgment needed for the exam.
Step 4: Practice architecture decisions
Hands-on experience is one of the most effective ways to reinforce your knowledge.
Use an Azure sandbox or controlled test environment to compare services, configure sample workloads, and evaluate design options. Monitor costs if you’re using a paid subscription.
For every exercise, ask:
- Why would I recommend this service?
- What alternatives exist?
- What are the security, availability, and cost implications?
- How would the solution change if business requirements changed?
Step 5: Use practice assessments
Microsoft provides a free AZ-305 Practice Assessment through AI Skills Navigator, accessible from its certification page. Sign-in is required.5
Use practice questions to identify weak areas rather than memorizing answers. Review incorrect responses and understand why the other options are less suitable.
Step 6: Prepare for the exam experience
Before scheduling your exam, try Microsoft’s exam sandbox to familiarize yourself with the interface and question formats.
Book through the official AZ-305 exam page and review your appointment details, identification requirements, and testing options.
We also recommend checking that your Microsoft Learn certification profile uses an account you’ll retain long term.
AZ-305 exam-day tips
The exam tests your ability to evaluate technical choices against business requirements.
A few habits can help:
- Identify the scenario’s key requirements before reviewing the answer options.
- Look for constraints involving security, availability, performance, compliance, and cost.
- Eliminate solutions that violate a stated requirement, even if they could technically work.
- Manage your time carefully, especially during case studies.
- Review answers before leaving a section that cannot be revisited. Microsoft notes that once you leave a case study, you cannot return to its questions.
- You can use Microsoft Learn during the exam. However, access is restricted to supported Microsoft Learn content. You can’t freely browse external websites, and the exam timer continues running while you search, so use this feature for occasional reference checks, not as a substitute for preparation.
Pro tip: keep in mind that the best architecture isn’t always the most sophisticated one, but the one that meets the requirements with appropriate trade-offs.
