Preparation for the AWS Certified Developer Associate Exam

My main preparation resource for the AWS developer associate certification exam was the Whizlabs AWS CDA online course that provides a focused content to pass the AWS CDA exam in the first attempt. The course provides 15+ hours of training videos with few interactive labs along with hands-on practice labs to gain real-time experience.

I completed the online course for the AWS developer associate certification exam that covers a comprehensive set of videos under the following sections:

  • Introduction
  • Getting Started
  • Core Services
  • Command Line Interface
  • Serverless
  • CI/CD and Developer Tools
  • Security
  • Additional Key Services

After the completion of the online video course, I also tried Whizlabs AWS CDA practice tests to check if I’m well-prepared. I tried practice tests 2 times, scored 80% above in the first attempt while 90% above in the second attempt and so in the real exam.
