Recently, I achieved the Microsoft Azure Fundamentals (AZ-900) certification. While the certification is considered an entry-level Azure exam, the journey taught me several valuable lessons about cloud computing, exam preparation, and continuous learning.
Why I Decided to Pursue AZ-900
As a software engineer, I wanted to strengthen my understanding of cloud concepts and Azure services. Although I work primarily in application development, cloud technologies have become an essential part of modern software delivery. AZ-900 provided a structured way to build foundational knowledge across cloud concepts, architecture, security, governance, networking, storage, and cost management.
My Preparation Approach
I primarily relied on Microsoft Learn modules and practice assessments. Initially, I focused on understanding concepts rather than memorizing answers. Topics such as cloud service models (IaaS, PaaS, SaaS), Azure regions, availability zones, virtual networks, storage services, and governance tools formed the core of my preparation.
One of the biggest lessons I learned was that understanding the differences between similar services is critical. For example:
- Azure Policy vs RBAC
- Azure Monitor vs Application Insights
- VPN Gateway vs ExpressRoute
- Azure Advisor vs Azure Migrate
- Availability Zones vs Region Pairs
Many exam questions are scenario-based and require understanding when to use a specific service rather than simply knowing its definition.
Challenges During Preparation
Practice assessments were not always consistent. My scores fluctuated across attempts, which was initially discouraging. Some assessments focused heavily on governance and monitoring, while others emphasized architecture and networking concepts.
Instead of focusing solely on scores, I reviewed every incorrect answer and created flashcards for recurring weak areas. This approach helped me improve my understanding and confidence over time.
Exam Experience
The exam tested both foundational concepts and practical scenarios. Reading questions carefully was important because Microsoft often includes keywords that point directly to the correct service or feature.
A few tips from my experience:
- Understand concepts instead of memorizing answers.
- Focus on service selection scenarios.
- Review governance and monitoring topics thoroughly.
- Use practice assessments to identify weak areas.
- Stay calm during the exam and avoid overthinking questions.
Final Result
I successfully passed the AZ-900 certification exam and earned the Microsoft Azure Fundamentals certification.
More importantly, the journey improved my understanding of cloud computing fundamentals and provided a stronger foundation for future Azure learning paths.
Key Takeaway
Certification is not just about passing an exam. It is about building confidence, learning new concepts, and creating a foundation for future growth. Every practice test, mistake, and revision contributed to the final outcome.
For anyone considering AZ-900, my advice is simple: focus on understanding the concepts, practice consistently, and don't get discouraged by practice assessment scores. Progress matters more than perfection.
