Amazon Web Services (AWS) leads the cloud computing industry, providing solutions and services that enable organisations worldwide to thrive in data management, storage, and machine learning (ML). With machine learning becoming a strategic priority for companies of all sizes, achieving AWS Certified Machine Learning opens doors to lucrative and high-demand roles. This guide details everything you need to know to succeed on the AWS Certified Machine Learning Specialty (MLS-C01) exam and establish a strong career foundation in ML on AWS.
Overview of the AWS Certified Machine Learning Specialty Exam
The AWS Certified Machine Learning – Specialty (MLS-C01) certification is designed for professionals who want to demonstrate their expertise in building, deploying, and securing machine learning models on AWS. This exam covers data engineering, model training, deployment, and the effective implementation of ML solutions using AWS tools like SageMaker, Comprehend, Polly, and Rekognition.
Passing this exam not only validates your ML skills on the AWS platform but also sets you apart as an ML expert capable of handling end-to-end machine learning projects, from data preparation to model deployment.
Exam Domains and Preparation Strategy
Domain 1: Data Engineering (20%)
This domain assesses your knowledge of data ingestion and preparation, foundational for effective ML modeling. Key areas include:
Data Repositories: Building storage systems to house large datasets.
Data Ingestion: Selecting the optimal data ingestion techniques, including batch and streaming methods using AWS services like Kinesis, Glue, and Data Pipeline.
Data Transformation: Cleaning, transforming, and managing data for ML readiness.
Study Tips:
Practice setting up data pipelines with AWS Glue and Kinesis.
Familiarize yourself with data transformation best practices in AWS.
Domain 2: Exploratory Data Analysis (24%)
