AZ-104 vs AZ-305 – AZ-104 must come before AZ-305. AZ-104 (Azure Administrator Associate) is a formal prerequisite for the Azure Solutions Architect Expert certification – you cannot earn AZ-305 without also holding AZ-104. The right time to move from AZ-104 to AZ-305 is after 6 to 12 months of hands-on Azure administration experience, when you have genuinely done the implementation work that AZ-305 asks you to design.
You do not choose between these two certifications. You earn both – in order.

Is AZ-104 a Prerequisite for AZ-305?
Yes – AZ-104 is a mandatory prerequisite for the Azure Solutions Architect Expert certification. You cannot earn the AZ-305 certification without also holding an active AZ-104 credential.
You can technically sit the AZ-305 exam without first passing AZ-104 – Microsoft does not block you from registering. But passing AZ-305 alone does not earn you the Azure Solutions Architect Expert certification. To receive the expert-level credential, you must hold both an active AZ-104 and a passing AZ-305 score simultaneously.
This is one of the most searched and most misunderstood facts about the Azure certification path. The official answer from Microsoft’s community forum is clear: you need both AZ-104 and AZ-305 to earn the Solutions Architect Expert certification. You can sit them in either order but you must have both active.
The practical recommendation: Take AZ-104 first. The implementation knowledge it builds is exactly what AZ-305 architecture scenarios assume you already have. Attempting AZ-305 without AZ-104 level knowledge is like designing a building without knowing how construction works.
What Is the Difference Between AZ-104 and AZ-305?
The core difference between AZ-104 and AZ-305 is the difference between doing and deciding.
AZ-104 tests the how. Can you create a virtual network with three subnets? Can you configure a Network Security Group? Can you set up Azure Backup for a virtual machine? Can you implement RBAC with a custom role? These are operational tasks that an administrator performs daily.
AZ-305 tests the why and the what. Given a company with 500 employees, a compliance requirement for data residency in the UK, a budget constraint of $50,000 per month, and a requirement for 99.99 percent availability – what Azure architecture do you recommend? Which storage solution is right? Which identity pattern fits? How do you design for disaster recovery without exceeding the budget?
AZ-305 does not ask you to click through the Azure Portal. It asks you to choose between valid options under real-world constraints. That is a fundamentally different cognitive skill – and it requires the implementation experience that AZ-104 and real Azure work provide.
What Does Each Exam Actually Cover?
AZ-104 Exam Domains
| Domain | Weight | What You Do |
| Manage Azure identities and governance | 15-20% | Configure Entra ID, RBAC, Azure Policy, subscriptions, resource locks |
| Implement and manage storage | 15-20% | Storage accounts, Blob storage, Azure Files, lifecycle policies, redundancy |
| Deploy and manage Azure compute resources | 20-25% | VMs, scale sets, App Service, Container Instances, AKS basics |
| Implement and manage virtual networking | 15-20% | VNets, NSGs, VPN Gateways, DNS, Load Balancer, Application Gateway |
| Monitor and maintain Azure resources | 10-15% | Azure Monitor, Log Analytics, Azure Backup, Site Recovery |
AZ-305 Exam Domains
| Domain | Weight | What You Design |
| Design identity, governance, and monitoring solutions | 25-30% | Identity architecture, governance frameworks, monitoring strategy, logging design, compliance solutions |
| Design data storage solutions | 20-25% | Relational and non-relational database selection, data lake architecture, data integration patterns, disaster recovery for data |
| Design business continuity solutions | 15-20% | High availability patterns, backup and restore strategy, disaster recovery design, RTO and RPO requirements |
| Design infrastructure solutions | 25-30% | Compute architecture selection, network topology design, application architecture patterns, migration strategy, cost optimization |
The critical difference in question style:
AZ-104 question: “You need to ensure that only members of the HR department can read files in a specific Azure Blob container. What should you configure?”
AZ-305 question: “A company is migrating a legacy application to Azure. The application requires high availability across two regions, must comply with GDPR data residency requirements for EU customers, has a peak load 10 times normal during month-end processing, and must minimize costs during off-peak periods. What architecture do you recommend?”
AZ-305 questions have no single obviously correct answer. They have the most correct answer given the specific combination of constraints stated in the scenario. This is why real-world architectural experience matters so much – you need pattern recognition built from actually designing and delivering Azure solutions.
AZ-104 vs AZ-305: Difficulty Comparison
AZ-305 is harder than AZ-104 – but not in the way most candidates expect.
| Factor | AZ-104 | AZ-305 |
| Type of difficulty | Technical depth and hands-on precision | Judgment depth and trade-off reasoning |
| Hardest part | Live lab simulations under time pressure | Case study scenarios with multiple valid options |
| Can you memorize your way through? | No – labs require actual skills | No – scenarios require judgment |
| Most common failure reason | Insufficient hands-on lab practice | Insufficient architectural experience and pattern knowledge |
| Pass rate for prepared candidates | 60 to 70 percent | 55 to 65 percent |
| Lab simulations | Yes – configure real Azure resources | No – judgment scenarios only |
| Study approach | Study plus build in Azure Portal daily | Study plus review architectural patterns and case studies |
The AZ-305 trap: Many AZ-104 holders assume AZ-305 is easier because it has no live labs. It is not easier. It tests a harder cognitive skill – architectural judgment under constraints – that cannot be developed through studying alone. Candidates who attempt AZ-305 immediately after passing AZ-104 without gaining real architectural experience between the two consistently struggle with the scenario depth.
When Should You Move from AZ-104 to AZ-305?
Move from AZ-104 to AZ-305 when you have spent meaningful time doing real Azure administration work – not immediately after passing AZ-104.
The Recommended Timeline
| Your Situation | When to Attempt AZ-305 |
| Just passed AZ-104, no prior Azure admin experience | Wait 6 to 12 months of real Azure admin work |
| Passed AZ-104, 1 to 2 years Azure admin experience | You are ready – attempt AZ-305 within 4 to 8 weeks of study |
| Passed AZ-104, 2 plus years Azure admin experience | You are likely ready – 4 to 6 weeks of focused study |
| Passed AZ-104, senior Azure admin role | You may be ready immediately – assess with practice exams |
| AWS Solution Architect with AZ-104 | You are ready – 4 to 6 weeks to cover Azure-specific patterns |
Why experience matters so much for AZ-305: The exam presents multi-constraint architectural scenarios where multiple options are technically valid. Only candidates who have encountered these trade-offs in real engagements develop the pattern recognition to consistently choose the most correct option. This is the insight that study materials cannot fully replace.
AZ-104 vs AZ-305: Salary Comparison
| Certification | Entry Salary US | Average Salary US | Senior Salary US |
| AZ-104 alone | $65,000 to $88,000 | $95,000 to $130,000 | $130,000 to $161,000 |

How to Prepare for AZ-305
Step 1: Do not attempt AZ-305 until you understand WHY Azure services work the way they do. AZ-104 teaches you how to configure services. AZ-305 tests whether you understand the reasoning behind Azure’s architectural patterns. Before studying for AZ-305, spend time asking “why does Azure work this way?” for every service you know. Why does Azure recommend zone-redundant storage over geo-redundant storage in some scenarios? Why would you choose Application Gateway over Azure Front Door? These judgment questions are what the exam tests are.
Step 2: Complete the official Microsoft Learn AZ-305 learning path. Microsoft provides a free official learning path for AZ-305 covering all four domains. It is structured around architectural decision-making rather than configuration steps. Complete every module and pay particular attention to the “design considerations” and “trade-off” sections that the AZ-104 path does not emphasize.
Step 3: Study architectural patterns and Well-Architected Framework. The Microsoft Azure Well-Architected Framework – covering reliability, security, cost optimization, operational excellence, and performance efficiency – is the mental model behind AZ-305 scenario answers. Study it explicitly, not as a side topic. Many AZ-305 questions reduce to “which option best satisfies the Well-Architected Framework pillar most relevant to this scenario?”
Step 4: Practice case studies under time pressure. AZ-305 case studies present a shared scenario with multiple questions. You must read the scenario, understand all constraints, and answer multiple related questions drawing from the same context. Practice this specific format – it is different from answering standalone multiple-choice questions and requires a different reading and reasoning approach.
Step 5: Review architectural diagrams for common Azure patterns. High availability patterns, hub-and-spoke networking, landing zone architectures, multi-region active-active and active-passive designs, and microservices patterns on AKS all appear in AZ-305 scenarios. Review reference architectures on Azure Architecture Center and understand when each pattern applies and what its trade-offs are.
Step 6: Use current practice materials. Our Microsoft exam preparation section covers current active Microsoft certifications including AZ-305.
The Complete Azure Certification Career Path
Understanding exactly where AZ-104 and AZ-305 fit in the full Azure career journey helps you plan your 2 to 5 year roadmap:

Who Should Prioritize AZ-305 Now?
Pursue AZ-305 now if:
You hold active AZ-104 and have 1 or more years of genuine Azure administration experience. Every month you delay the architect credential is a month you are paid at administrator rates for work that increasingly involves architectural thinking.
You are in a consulting role where the AZ-305 credential directly affects the projects you qualify for and the rates you can charge. Architecture-level consulting commands significantly higher billing rates than administration-level work.
Your current employer has senior architect positions that require AZ-305 for promotion or project leadership. If the credential is attached to a concrete career opportunity, the ROI calculation is immediate.
Wait on AZ-305 if:
You passed AZ-104 less than 6 months ago and have not yet worked in a hands-on Azure administration role. Attempting AZ-305 immediately after AZ-104 without real architectural experience is the most common reason candidates fail their first AZ-305 attempt. The $165 retake fee is avoidable by waiting until you are genuinely ready.
Your current role is narrowly focused on a single Azure service area. AZ-305 expects broad architectural knowledge across compute, storage, networking, identity, and data. Candidates whose Azure experience is deep in one area but shallow across others consistently find certain AZ-305 domains underprepared. Broaden your real-world exposure before sitting the exam.
Frequently Asked Questions: AZ-104 vs AZ-305
What is the difference between AZ-104 and AZ-305?
AZ-104 tests practical Azure administration skills – configuring, managing, and monitoring Azure environments daily. AZ-305 tests Azure architecture skills – designing solutions that meet business requirements for scalability, availability, security, and cost. AZ-104 is associate level. AZ-305 is expert level. AZ-104 is required before you can earn AZ-305.
Is AZ-104 required before AZ-305?
Yes. You must hold an active AZ-104 to earn the Azure Solutions Architect Expert certification. You can sit the AZ-305 exam without AZ-104 but passing it alone does not earn you the certification. You need both active credentials simultaneously.
Which is harder – AZ-104 or AZ-305?
Both are challenging but in different ways. AZ-104 has live lab simulations requiring hands-on Azure configuration skills. AZ-305 has complex multi-constraint architectural case studies requiring judgment and pattern recognition. AZ-305 is harder for candidates who lack real-world architectural experience regardless of their technical depth.
How much does AZ-305 pay?
Azure Solutions Architects with AZ-305 earn $130,000 to $180,000 on average in the US. Senior architects and principal architects earn $170,000 to $220,000. The salary jump from AZ-104 to AZ-305 level roles is typically $25,000 to $50,000 per year.
How long does AZ-305 take to prepare for?
Most candidates with 1 to 2 years of Azure administration experience need 8 to 12 weeks of part-time study after passing AZ-104. Candidates with 2 or more years of experience may be ready in 4 to 6 weeks.
Can I take AZ-305 without AZ-104?
You can sit the AZ-305 exam without first passing AZ-104 – Microsoft does not block registration. However, you will not receive the Azure Solutions Architect Expert certification without AZ-104. Both credentials must be active simultaneously for the expert certification to be issued.
How long should I wait between AZ-104 and AZ-305?
Most candidates benefit from 6 to 12 months of hands-on Azure administration work between the two exams. This real-world experience builds the architectural pattern recognition that AZ-305 case studies require. Candidates with 2 or more years of existing experience may move straight to AZ-305 within weeks of passing AZ-104.
Does AZ-305 have lab simulations?
No. AZ-305 does not include live lab simulations. It uses multiple choice questions and case study scenarios that test architectural judgment and design decisions. AZ-104 includes the live labs – AZ-305 removes them but replaces them with significantly more complex scenario reasoning.
What comes after AZ-305?
After AZ-305, common next steps include AZ-400 (Azure DevOps Engineer Expert) for professionals moving into cloud automation and CI/CD, SC-500 (Cloud and AI Security Engineer) for security specialization, or specialization certifications like DP-700 for data engineering. Many AZ-305 holders also pursue multi-cloud credentials to add AWS or Google Cloud to their profile.
Is AZ-305 worth it?
Yes. AZ-305 is one of the highest-ROI expert-level certifications in enterprise IT. The average salary for Azure Solutions Architects is $130,000 to $180,000 – a $25,000 to $50,000 premium over AZ-104 level roles. The credential is recognized globally and is specifically listed as a requirement in senior architect job postings.
What is the Azure Well-Architected Framework and why does it matter for AZ-305?
The Azure Well-Architected Framework covers five pillars – reliability, security, cost optimization, operational excellence, and performance efficiency. AZ-305 exam scenarios frequently reduce to choosing the option that best satisfies the most relevant pillar given the specific constraints stated. Understanding the framework’s trade-offs is essential preparation.
