Description
This final module brings together everything you’ve learned across the course and helps you strategically prepare for the AZ-305: Designing Microsoft Azure Infrastructure Solutions exam.
You’ll review key domains, practice real-world scenario questions, understand common pitfalls, and learn smart tactics for managing time, interpreting tricky scenarios, and using the exam interface effectively.
The goal of this module is not just to help you pass the exam — but to ensure you can think, reason, and design like a true Azure Solutions Architect.
1: Understanding the AZ-305 Exam Blueprint
Overview
The AZ-305 exam measures your ability to design end-to-end Azure solutions that balance security, scalability, reliability, and cost. It assumes you already have hands-on implementation skills (from AZ-104 or real experience).
Microsoft skill domains and weightage:
-
Design Identity, Governance, and Monitoring Solutions → ~25–30%
-
Design Data Storage Solutions → ~20–25%
-
Design Business Continuity Solutions → ~15–20%
-
Design Infrastructure Solutions → ~25–30%
Exam Format:
-
~40–60 questions.
-
Question types: multiple choice, drag-and-drop, case studies, sequence design, yes/no multiple responses.
-
Duration: 120 minutes (150 including survey).
-
Passing score: 700 / 1000.
Key Tip
You’ll see scenario-based questions where multiple answers look correct — but the “best” answer balances security + performance + cost + manageability.
2: Exam-Focused Design Scenarios
Example Scenarios
1. Identity & Governance
Company requires centralized identity for hybrid users, conditional access, and least privilege.
Answer: Use Entra ID + PIM + Conditional Access + Management Groups.
2. Networking
Multi-region deployment with latency optimization.
Answer: Azure Front Door + Traffic Manager + Private Endpoints + NSGs.
3. Data Storage
High throughput transactional app + analytical workloads.
Answer: Azure SQL Managed Instance + Synapse / Data Lake integration.
4. Business Continuity
Compliance requires RTO < 5 min, RPO < 15 min.
Answer: Azure Site Recovery + Geo-redundant Storage (GRS).
5. Security & Compliance
Healthcare system requiring data confidentiality and audit logs.
Answer: Always Encrypted + Key Vault (CMK) + Defender for Cloud.
3: Common Pitfalls & How to Avoid Them
1. Ignoring the “Design” Perspective
-
AZ-305 tests architecture trade-offs, not just which service fits.
Tip: Always justify design with cost, manageability, and resilience.
2. Mixing Up Similar Services
-
Front Door vs Traffic Manager → layer difference (7 vs DNS-based).
-
Event Hub vs Service Bus → streaming vs messaging.
-
Azure Firewall vs NSG → stateful vs stateless.
Tip: Build a “compare & contrast” table before the exam.
3. Over-Engineering
-
If two answers meet requirements, choose simpler + cheaper + compliant design.
4. Ignoring Dependencies
-
Example: Assigning private endpoints without DNS update = broken connectivity.
5. Forgetting Identity Integration
-
Always consider RBAC, Managed Identity, and Policy inheritance in solutions.
4: Time Management & Question Strategy
Tips:
-
Start with case studies last — they consume time.
-
Mark difficult questions and revisit.
-
Use elimination: remove answers violating compliance, scalability, or cost principles.
-
Spend <2 minutes per question on average.
-
Read carefully: the exam often includes keywords like minimize cost, reduce latency, ensure compliance, or simplify management — these are design drivers!
5: Final Revision Plan & Study Checklist
1. Pre-Exam Day
-
Review Microsoft Learn skill outline.
-
Re-read all module summaries (especially Governance, Identity, and Business Continuity).
-
Practice with free MS Learn sample questions.
-
Sleep well — brain fatigue kills reasoning ability.
2. Exam Day Strategy
-
Skim all questions once before answering.
-
Focus on understanding requirements, not symptoms.
-
Use the “Review” flag wisely — revisit unclear items later.
3. Quick Review Checklist
Governance & Management Groups
Conditional Access & PIM
Private Endpoints vs Service Endpoints
VNet Peering, VPN, ExpressRoute
Availability Zones & Geo-replication
App Gateway vs Front Door
Log Analytics vs App Insights vs Sentinel
Azure Policy, Blueprints, Tags, Budgets
Post-Exam Growth Path
Passing AZ-305 qualifies you as a Microsoft Certified: Azure Solutions Architect Expert (after AZ-104).
Next Steps for Continuous Growth:
-
Specialize in Security (SC-100, SC-300) or Data (DP-203).
-
Explore DevOps (AZ-400) for full solution lifecycle design.
-
Keep your certification active by renewing annually (free online).
