Aspirants, how are you preparing for the AWS Certified Developer Associate exam (AWS CDA).
Whizlabs aims to offer industry-leading study and practice materials that are up-to-date and relevant in line with the latest updates from Amazon Web Services. Whizlabs AWS Expert Team member, I took (and passed) the AWS Certified Developer Associate exam to keep track of the latest changes and to see if the online course Whizlabs AWS CDA is good enough for the AWS CDA certification exam.
Amazon Web Services offers three associate-level certifications, including the AWS Certified Developer Associate exam (DVA–C01). It allows candidates to demonstrate their ability to use AWS Certified Developer Associate exam (DVA-C01).
Understanding the core AWS services and their uses. Also, understanding AWS architecture best practices.
Expertise in cloud-based applications using AWS.
Preparation for the AWS Certified Developer Associate Exam (DVA-C01).
The Whizlabs AWS CDA online course was my main preparation tool for the AWS developer Associate certification exam. It provides focused content that will allow you to pass the AWS CDA exam on your first attempt. The course includes 15+ hours of training videos and a few interactive labs. You can also practice with the labs in real-time to gain real-world experience.
I passed the AWS developer associate certification exam by taking the online course. It covers the following sections:
Command Line Interface
Developer Tools and CI/CD
Additional Key Services
To make sure I was prepared for the online course, I took the Whizlabs AWS CDA practice test. I took two practice tests and scored 80% higher on the first attempt, while scoring 90% higher on the second. This was the same score as the real exam.
