Reference Materials


Jayendra’s Blog

This was an excellent resource for understanding the exam topics. The content is well-organized, and I recommend following this guide from start to finish on your learning path.

AWS Official Documentation

Practice Tests

WhizLabs - AWS Certified Big Data – Specialty

To be honest, I thought that it was not well-organized, had numerous typos and contained grammatical errors, which made it difficult to use.


The exam includes many questions related to Apache Hadoop ecosystem. If you are working with big data, this exam surely offers the good opportunity for learning.
