Brief Introduction
Prepare well for your AWS Certified Machine Learning Specialty certification by taking this practice exam!Description
Realistic practice exam based on the most recent AWS Certified Machine Learning Specialty exam.
Just like the actual exam this practice test has 65 questions and takes 170 minutes.
Questions are mapped based on the actual exam domains:
Data Engineering
Exploratory Data Analysis
Modeling
Machine Learning Implementation and Operations.
