- Performance tracking across every attempt
- A course leaderboard to compare your progress
- Unlimited opportunities to practise, improve and master each test
A Progressive Path to AZ-305 Mastery
Practice Test A — Core Azure Architecture Design
Begin with a comprehensive assessment covering the major responsibilities of an Azure Solutions Architect.
This test evaluates your ability to design solutions across identity, governance, networking, application hosting, data storage, integration, security and business continuity.
It establishes your baseline knowledge and helps identify which architecture domains require further revision before you progress to more demanding scenarios.
Practice Tests B–D — Case Study Architecture Assessments
Work through complete exams featuring detailed case studies based on realistic organisations, including Contoso, Fabrikam and Tailwind Traders.
Each assessment presents connected business goals, existing environments, technical requirements and operational constraints. You must analyse the complete scenario and select an architecture that satisfies the organisation’s security, performance, availability, scalability and cost requirements.
You will design solutions involving:
- Identity, access and governance
- Hybrid identity and infrastructure
- Azure networking and connectivity
- Application and compute architecture
- Data storage and database services
- Integration and messaging patterns
- Security and regulatory compliance
- High availability and disaster recovery
- Monitoring, management and automation
- Performance and cost optimisation
These case studies are designed to test your ability to connect multiple Azure services and make informed architecture decisions rather than answer isolated product questions.
Practice Test E — Advanced Multi-Service Architecture
Take on high-difficulty architecture scenarios that require you to evaluate competing Azure services, identify design trade-offs and recommend the most appropriate solution.
Questions may require you to balance availability, performance, security, operational complexity and cost while working within strict technical or business constraints.
This test strengthens your ability to:
- Compare multiple valid architecture approaches
- Identify the most important design requirement
- Evaluate service limitations and dependencies
- Select appropriate resiliency and scaling strategies
- Make architect-level recommendations under constraints
Final Mastery Test — Expert Solutions Architect Simulation
Complete your preparation with a demanding Final Mastery Test that combines concepts from across the entire AZ-305 curriculum.
This capstone assessment mirrors the most complex scenario, case-study and multi-step reasoning styles you may encounter in the official exam.
You will be required to evaluate complete Azure environments, interpret competing requirements and recommend secure, scalable, resilient and cost-effective architectures.
The Final Mastery Test is intentionally challenging, helping ensure that the official exam feels familiar and manageable.
Learn From Every Architecture Decision
Every question includes detailed feedback designed to build genuine architectural understanding.
You will learn:
- Why the recommended design is the best solution
- Why each alternative design fails to meet the requirements
- Which business or technical constraint determines the answer
- How different Azure services compare
- Which service limitations and dependencies must be considered
- How to recognise important clues within architecture scenarios
- How to avoid common design mistakes and misleading answer choices
This explanation-first approach helps you understand the reasoning behind each decision instead of relying on memorised answers.
Track Your Progress and Climb the Leaderboard
Monitor your scores, repeat assessments and compare your performance using the Harbourmetric leaderboard.
Use each attempt to identify weaker architecture domains, review the detailed explanations and improve your ability to solve complex design scenarios.
Achieving 80% or higher consistently across all six assessments is a strong indication that you understand the AZ-305 curriculum and are ready to schedule the official certification exam.
Build Real Azure Architecture Skills
By completing this course, you will strengthen your ability to:
- Design identity, authentication and authorisation solutions
- Develop governance and management strategies
- Design secure hybrid and Azure network architectures
- Select appropriate compute and application-hosting services
- Design relational, non-relational and analytical data solutions
- Recommend integration and messaging technologies
- Design for high availability and disaster recovery
- Evaluate security, compliance and operational requirements
- Balance performance, resiliency, scalability and cost
- Make confident architecture decisions across complex Azure environments
The knowledge developed throughout this course supports both certification success and real-world Azure architecture responsibilities.
Prepare with realistic design challenges, learn from every answer and build the confidence required to become a Microsoft Certified: Azure Solutions Architect Expert.
