- The trade-offs and limitations of various AWS tools in different scenarios.
This knowledge enhances your problem-solving skills and helps you make better decisions in real-world projects.
5. A Confidence Booster
Tackling one of the most challenging AWS certifications proves your mettle as a cloud and DevOps professional.
My Study Resources 📚
Preparing for this exam was no easy feat—it required a mix of structured study, hands-on projects, and real-world experience. Here’s how I approached it:
1. Stephane Maarek’s Course Udemy
A fantastic starting point! Stephane’s content is well-structured and directly aligned with the exam’s objectives. It helps you build a strong foundation.
2. Adrian Cantrill’s Course
Adrian’s material dives deep into the inner workings of AWS services, giving you a more nuanced understanding. This course is invaluable for grasping the "why" behind AWS architectures.
3. Practice Exams by Jon Bonso
These mock exams are essential. The structure, difficulty, and content are very similar to the real exam, making them great tools for gauging readiness.
4. AWS Skill Builder
I utilized AWS’s official practice exams on Skill Builder to validate my knowledge and identify weak areas. These tests are great for understanding AWS's preferred solutions and best practices.
5. AWS Whitepapers and FAQs
Reading AWS whitepapers, particularly those on CI/CD, monitoring, automation, and security, provided insights into best practices and design principles. The FAQs for services like CodePipeline, CloudFormation, and CloudWatch were also extremely helpful.
6. Do some hands-on project
My work as an AWS Cloud Consultant gave me invaluable hands-on experience with AWS services. Real projects taught me how services are used, their limitations, and the kind of decisions required in practical scenarios.
If you don't have this chance yet, spin up your own projects on AWS Account.
Key takeaway: Don’t just rely on courses. Build pipelines, set up monitoring, deploy scalable architectures, and troubleshoot real-world problems. The exam is heavily focused on use cases, and hands-on experience helps bridge the gap between theory and application.

Lessons Learned 💪
Hands-On Is a Game-Changer
Understanding AWS concepts is one thing; applying them in real scenarios is another. Building CI/CD pipelines, setting up monitoring systems, and troubleshooting issues in a real-world environment taught me far more than any course.
The Exam Is All About Use Cases
The questions often involve multiple AWS services working together to solve a specific problem. It’s crucial to understand how services interact and which service fits a given scenario best.
Important to mention that all the answer options could be implemented. You need to read carefully what is the requirement mentioned in the question (eg: cost-efficient, reduce management overhead or high avalibility)
Final Thoughts 🏅
This certification is challenging, but with the right preparation, anyone can achieve it. More importantly, certifications are not just about passing an exam—they’re about building a deeper understanding of cloud practices and enhancing your ability to solve real-world problems.
Remember ‼️‼️
Certification is great, but hands-on experience is what truly sets you apart. Dive into projects, experiment with services, and push yourself to apply what you learn.
To everyone considering the AWS DevOps Engineer - Professional exam: go for it! The journey will not only add value to your career but also significantly elevate your cloud expertise.
