AZ-305 Exam Snapshot
The Microsoft Certified: Azure Solutions Architect Expert (AZ-305) is the senior architect credential for Microsoft's stack. Earning it requires AZ-104 (or equivalent admin experience) plus AZ-305 itself. Microsoft pitched AZ-305 as a pure design exam — and they meant it.
Why "Design Only" Changes Everything
AZ-104 asks "how do I deploy a VM?". AZ-305 asks "given these requirements, which compute, network, identity, and data services design best meets cost + RTO + compliance?". The exam is heavy on case studies and "design considerations" framing. There are no "how to do X in the portal" questions.
The shift: AZ-305 grades architectural reasoning, not service knowledge. Knowing what Azure Storage is matters less than knowing when LRS beats GZRS for a given RTO/RPO target. AI practice trains the second skill specifically.
Why AI Practice Beats Static Banks for AZ-305
AZ-305 distractors are uniformly "technically correct" answers that fail on cost, latency, or compliance constraints. Static banks tell you "the answer is C." AI explanations walk through which constraint pinned the answer to C and what would flip it to D.
ai.examcert.app handles AZ-305 case studies inline — you see the case-study text alongside each related question, and the AI references specific case-study constraints in its explanation. That direct mapping is exactly the muscle the exam tests.
ExamCertAI AZ-305 Walkthrough
Step 1: Open ai.examcert.app and pick AZ-305
Choose Azure Solutions Architect Expert (AZ-305). Two modes: exam mode (timed, mirrors Microsoft's flow including case studies) and study mode (immediate AI explanations, follow-ups).
Step 2: Take a baseline including case studies
Run a full-length exam-mode test cold. Most candidates lose 5-10% on case studies vs discrete questions, so you need to know your case-study performance specifically — ExamCertAI separates the two in the domain breakdown.
Step 3: Switch to study mode for weak design areas
For each missed question, ask the AI two follow-ups designed to surface the design framing:
- "What design constraint pinned the answer to C? What would flip it to D?"
- "Compare this to a hub-and-spoke topology. When does each win?"
- "Why is GZRS the wrong answer here when it would be right with a different RTO?"
Step 4: Drill case studies separately
Run study-mode sessions filtered to case-study questions. Re-read each case study carefully before answering. The exam often hides the decisive constraint in sentence 6 of paragraph 3 of the case study.

Launch ExamCertAI →A Real AZ-305 Question, Reviewed With AI
A company runs a workload with RTO of 1 hour and RPO of 15 minutes. The workload uses Azure SQL Database in the East US region. The architecture must remain operational if the East US region fails entirely. Which design BEST meets the requirements at minimum cost?
A. Azure SQL Database with active geo-replication to West US (read-only secondary).
B. Azure SQL Database with auto-failover groups across East US and West US.
C. Azure SQL Database Hyperscale with zone-redundant configuration in East US only.
D. Azure SQL Database Business Critical tier with Always-On Availability Group across two East US zones.
Why the AI explains B as the right answer:
- The constraint is region failure, not zone failure. C (zone-redundant in East US only) and D (zones in East US only) cannot meet the requirement. Eliminate.
- Active geo-replication (A) gives you a read-only secondary — you must manually fail over and re-point applications, which can blow the 1-hour RTO.
- Auto-failover groups (B) provide a transparent failover endpoint that re-points reads/writes automatically. Meets the RTO without manual intervention.
- Cost: auto-failover groups use the same underlying geo-replication tech as A, so the price differential is small — you are paying for orchestration, not extra compute.
The AI offers: "What changes if RTO were 4 hours and budget were tight?" — a follow-up that builds the cost-optimization muscle.
The 6-Week AZ-305 Study Workflow
Microsoft Entra ID design (tenants, B2B/B2C, conditional access at scale), management groups, Azure Policy, Azure Monitor design choices.
Storage redundancy (LRS/ZRS/GRS/GZRS) by RTO/RPO, Cosmos DB consistency models, Azure SQL deployment options, blob lifecycle for cost.
Backup, ASR, geo-replication, auto-failover groups, multi-region designs. RTO/RPO trade-offs across services.
Compute (VMs, AKS, App Service, Functions, Container Apps), networking (hub-and-spoke, vWAN, ExpressRoute), application architecture patterns.
One full ExamCertAI session focused entirely on case studies. Re-read every case study. Target 75%+ before moving on.
Three full-length 120-minute exam-mode tests on ExamCertAI. Target 80%+ on each. Two days before exam: rest.
Plan Your AZ-305 Study Time
Common AZ-305 trap: picking the most-feature-complete service instead of the right-sized service. Cosmos DB strong consistency works for almost any data scenario but is wrong on AZ-305 if the question prioritizes cost — eventual consistency at 1/4 the price wins.
Frequently Asked Questions
Is the Azure AZ-305 AI practice test on ai.examcert.app really free?
Yes. ExamCertAI is browser-based with no signup, no credit card, no download. You get full-length AZ-305 simulations including case-study sections with AI explanations on every option.
Should I take AZ-104 before AZ-305?
Microsoft no longer requires it as a prereq, but practically, AZ-305 assumes you can identify the right Azure service for a given workload. Without AZ-104 fluency or 1-2 years of Azure architecture experience, AZ-305 will feel impossibly broad.
How is AZ-305 different from the older AZ-303 / AZ-304?
Microsoft consolidated AZ-303 (technologies) and AZ-304 (design) into a single AZ-305 (design) exam in 2022. AZ-305 is purely design-focused: identity, governance, data flow, business continuity, infrastructure. No more "how to deploy a VM" questions.
What target score should I hit on AI practice tests before booking AZ-305?
Aim for 80%+ on at least two consecutive timed full-length simulations including case studies. AZ-305 passing is 700/1000. An 80%+ practice average gives buffer; case-study sections on the real exam tend to score 5-10% lower than discrete questions.
