Recently, I passed my AWS Certified Developer Associate certification (DVA C02 exam and I was able to score 905 marks in the same. I expected a good mark, but not this great. Here in this read, you will find a detailed guide and tips that helped in my preparation. This is going to be unlike other experiences. I’ll share how stress-free and confident I was prepared to attain a great score on my first attempt. Let’s give it a read.
To start with,
My Cloud Career journey
I came from a non-development background, and it was completely overwhelming and different at the start. I stumbled upon the vast Service group of AWS, stood unsure, and had no clarity. To start off with, I took the Cloud Practitioner certificate as my foundation out of serious Research. It was told to dive into the basics of the ecosystem and navigate exclusively different services. However, theories felt Greek and Latin initially, I would say practical learning with real-time tests and lab experience shot up my confidence. Eventually, coding came in like a calming breeze, and yes, of course, I found joy in doing it. This interest has now become the starting point for my passion to get my hands on creating, automating and deploying. That’s me here today writing this as I passed the AWS Developer Associate.
Why choose DVA among other certifications?
When I looked for associate roles after, from Solution Architect to SysOps associate, the options are vast and here are the strengths. SAA where you understand architectures, and SysOps opening up to operations. I mostly aligned with Real development tasks like SDKs, writing lambda functions, deploying APIs, CI/CD integration and more. As my inference mostly relies on building a scalable system and a reliable background in cloud DVA is my pick. In the process of building a monolithic application into microservices, it opens doors to many technical roles.
Benefits of taking the Developer Associate
- It’s a stepping stone for advancing in DevOps and Architecture roles.
- The AWS Developer Associate lays a strong foundation for cloud-native apps and modern CI/CD.
- Get insights on AWS SDKs and API integrations, and a great edge for backend DevOps roles.
- It’s recognised by employers for developer roles, mainly in startups and enterprises leveraging microservices.

What’s my Exam day strategy for AWS Certified Developer Associate?
To start with, Setup and Mindset, I was very much focusing on being calm and aware. I made sure the desk was clean, ensured there was stable internet and also tested my webcam. I was concise on what I ate, a light meal, and had a water bottle handy. Avoided learning new things, instead just skimmed through all the service limits, core policies, etc.
Coming to the time management part, I started with some questions and answered them. I flagged the tough ones and then went to the difficult set with fresh focus. I aimed to finish the test by 40minutes and planned to review.
You can utilize the Flag feature in practice tests and mocks available to help you revisit the questions you are unsure about later. Don’t get panicked, breathe through difficult ones, and your instincts do a careful review, vitalise it.
Common Mistakes to Avoid
- Don’t misunderstand with IAM roles and policies, it might be confusing in the start like Trust relationships, implicit denies, explicit denies, etc., but the scenario will ask for the requirement, act accordingly.
- Missing out on practising SAM and CDK can affect giving equal importance to hands-on deployment.
- Don’t simply ignore Logging and Monitoring questions. CloudWatch Logs, metrics filters, X-Ray tracing, and alerts are key for troubleshooting. Try to configure each of them in the AWS account. bash aws logs create-log-group –log-group-name my-lambda-logs
- Over-relying on theories and skipping practical experience on deploying Lambda functions, updating IAM policies, and integrating API Gateway with real Lambda endpoints will not give completeness.
What helped me score 905 in AWS DVA C02 in reality?
- Concentrating on hands-on practice over Theories. Get to build Real projects like a REST API using Lambda, API Gateway, and DynamoDB. Then watch the theories to connect.
- Time box and review practice test on a serious note, no gimmick or being lethargic over it.
- Break down the wrong answer, learn, try and know it in detail.
- Don’t miss out on Reddit and forum sites.
What is Next after AWS Developer Associate?
If you ask me, I’m now trying to understand what best suits my career and niche focus. Here are the top picks.
