Hi @jia-whitaker ,
This is a question we have heard quite a bit as Amazon rolled out the Data Analytics Specialty. The Exam outlines, as you have read are nearly identical, save some minor language variance. The main differences are:
If I may take a stab at the question behind the question: can we use Big Data materials to prepare for the Data Analytics exam? The answer is yes, and.
Yes, the Big data video and notes here on ITProTV launched in 2019; the DA exam launched in 2020. Partnering the ITProTV materials with current vendor resources will be an effective pairing. So, yes, use the Big Data materials and use current resources to fine-tune your studies while focusing your attention according to the new domain weights.
