How to Pass AZ-305 Azure Solutions Architect Expert in 15 Days: 2026 Coach Roadmap
A day-by-day 15-day study plan for the AZ-305 Azure Solutions Architect Expert exam in 2026. Covers all 4 domains, why AZ-305 is harder than AZ-104, case study strategies, free resources, and a CertLand practice exam with 380 hard-difficulty questions.
The AZ-305 Designing Microsoft Azure Infrastructure Solutions exam earns you the Microsoft Certified: Azure Solutions Architect Expert credential -- one of the most respected cloud certifications in the industry. Unlike AZ-104 (which tests how to DO things), AZ-305 tests how to DESIGN things: choosing the right services, balancing cost vs performance vs SLA requirements, and designing for resilience.
This guide gives you a complete 15-day study plan with daily targets, study strategies specific to AZ-305's unique format, and the resources you need to pass on your first attempt.
AZ-305 Exam Overview (2026)
| Detail | Value |
|---|---|
| Questions | 40-60 questions (including case studies, multiple choice, drag-and-drop) |
| Duration | 120 minutes |
| Passing Score | 700 / 1000 |
| Price | $165 USD |
| Prerequisite | Active AZ-104 Azure Administrator Associate certification |
| Credential Earned | Microsoft Certified: Azure Solutions Architect Expert |
Important:
AZ-305 requires an active AZ-104 certification as a prerequisite. You must pass AZ-104 before or at the same time as AZ-305 to earn the Azure Solutions Architect Expert credential. If your AZ-104 expires, your Expert credential also expires.

Why AZ-305 Is Harder Than AZ-104
AZ-305 has a higher failure rate than AZ-104, and the reasons are structural, not just content-related:
- Case studies: AZ-305 includes case studies with 1-2 pages of business requirements, technical constraints, and diagrams. You must read everything before answering 4-5 related questions. Missing one detail can lead to wrong answers across multiple questions.
- Multi-constraint scenarios: Questions rarely have a single constraint. A typical question might say: "minimize cost AND ensure 99.95% SLA AND support cross-database queries AND maintain HIPAA compliance." You must find the service that meets ALL constraints simultaneously.
- "Minimize cost" traps: Many questions include "minimize cost" as a requirement. This does not mean "pick the cheapest option." It means "pick the cheapest option that meets ALL other requirements." Candidates who default to the cheapest service without checking SLA or feature requirements fail these questions.
- Breadth of knowledge: AZ-305 covers everything from identity architecture to messaging patterns to database selection to DR design. You need to know dozens of services at a design-decision level.
Case Study Strategy:
Read the case study requirements section FIRST (not the background). Highlight key constraints: SLA targets, compliance standards, budget limits, latency requirements. Then read the questions. Only go back to the background section when a question references a specific detail.
The 15-Day AZ-305 Study Plan
This plan assumes 3-4 hours of focused study per day. AZ-305 requires deeper study sessions than AZ-104 because you need to understand trade-offs, not just features.
| Day | Focus Area | Activities |
|---|---|---|
| Day 1 | Identity Architecture | Entra ID architecture decisions: single vs multi-tenant, B2B vs B2C, hybrid identity (Entra Connect sync vs cloud sync), Conditional Access policies. Build a decision tree. |
| Day 2 | Governance and Compliance | Management group hierarchy design, Azure Policy vs Azure Blueprints, landing zone architecture, Microsoft Defender for Cloud, regulatory compliance (HIPAA, SOC2, PCI-DSS). |
| Day 3 | Monitoring and Logging | Azure Monitor design, Log Analytics workspace architecture, Microsoft Sentinel (SIEM), Application Insights, diagnostic settings, workbook dashboards. |
| Day 4 | SQL Database Solutions | SQL DB vs SQL MI vs SQL on VM decision matrix. Elastic pools, serverless tier, geo-replication, auto-failover groups. When to choose each option. |
| Day 5 | NoSQL and Analytics | Cosmos DB (APIs, consistency levels, partitioning), Data Lake Gen2, Azure Synapse Analytics, Azure Databricks, HDInsight. Build comparison tables. |
| Day 6 | Storage Design | Storage account redundancy design, access tier strategies, blob lifecycle policies, Azure Files vs Azure NetApp Files, storage encryption, immutable blobs. |
| Day 7 | Business Continuity: Backup and DR | Azure Backup policies, Azure Site Recovery, RTO vs RPO definitions, DR strategies (backup-restore, pilot light, warm standby, active-active), cost vs recovery trade-offs. |
| Day 8 | High Availability Design | Availability sets vs zones, SLA calculations (composite SLA), multi-region active-active vs active-passive, traffic routing during failover, database HA (auto-failover groups, Cosmos DB multi-region writes). |
| Day 9 | Networking: Load Balancing | 4-way load balancing decision: Front Door vs Traffic Manager vs Application Gateway vs Load Balancer. Global vs regional, L4 vs L7, WAF, CDN. Build the decision table. |
| Day 10 | Networking: Connectivity | ExpressRoute vs VPN Gateway, Azure Virtual WAN, hub-spoke topology, private endpoints, DNS design (Azure Private DNS, conditional forwarders). |
| Day 11 | Compute: Containers and Serverless | AKS vs Container Apps vs Container Instances decision, Azure Functions (consumption vs premium), Durable Functions patterns (fan-out/fan-in, chaining, human interaction), Logic Apps. |
| Day 12 | Messaging and Integration | Service Bus vs Event Grid vs Event Hubs decision, API Management, Azure Cache for Redis, IaC (Terraform vs Bicep). Build the messaging decision table. |
| Day 13 | Case Study Practice | Work through 3-4 case studies. Practice identifying constraints, mapping requirements to services, and time management (8-10 minutes per case study). |
| Day 14 | Full Practice Exam | Take a full 380-question practice exam on CertLand with hard difficulty filter. Review every wrong answer. Identify weak domains and build a targeted review list. |
| Day 15 | Weak Area Review and Decision Tables | Review all decision tables (load balancing, messaging, SQL, DR strategies). Re-read exam traps. Take a timed 50-question drill on weak domains. |
AZ-305 Study Tips
Tip #1: Build decision tables, not flashcards.
AZ-305 tests your ability to choose between similar services under constraints. Create side-by-side comparison tables for every major service group: SQL databases, messaging, load balancers, compute options, DR strategies. These tables are your most valuable study tool.
Tip #2: Always check all constraints before selecting an answer.
AZ-305 questions typically have 3-4 requirements embedded in the scenario. Read every sentence. The correct answer is always the one that meets ALL requirements simultaneously -- not just the most obvious one.
Tip #3: "Minimize cost" has a specific meaning.
When a question says "minimize cost," it means: find the cheapest option that MEETS (not exceeds) all stated requirements. If a workload requires 99.99% SLA, the cheapest Standard tier that meets 99.99% is correct -- even if a Basic tier is cheaper but only offers 99.9%.

Final Advice: Exam Day Strategy
AZ-305 exam-day strategies differ from AZ-104:
- Case studies first: Some candidates skip case studies and come back later. This is a mistake -- case study questions cannot be revisited once you leave the section. Read carefully and answer all case study questions before moving on.
- Time budgeting: Allocate 8-10 minutes per case study (typically 2-3 case studies) and 1.5-2 minutes per standalone question.
- Eliminate by constraint: For multi-constraint questions, start by checking which options meet the SLA or compliance requirement. Usually only 1-2 options survive. Then check cost among those survivors.
- Trust your decision tables: If you built the comparison tables during study, you will recognize patterns instantly. Load balancing? Global L7 = Front Door. Messaging with guaranteed delivery? Service Bus.
The Azure Solutions Architect Expert credential is a career differentiator. It shows employers you can design complete Azure solutions, not just implement individual services. Invest the 15 days, build your decision tables, and you will pass.
