Free MLA-C01 practice exams are now available for the AWS Certified Machine Learning Engineer Associate, AWS's associate-level certification for engineers who build, deploy, and operate ML workloads on AWS. If you spend your day in SageMaker, work with feature pipelines, or operate production endpoints, these practice questions help you confirm what you know before sitting the real exam.
What MLA-C01 covers
The MLA-C01 is targeted at engineers with around one year of hands-on AWS ML experience. It tests practical skills across the full ML lifecycle, with a heavy lean on SageMaker. You'll be asked about preparing data on AWS, choosing and tuning algorithms, deploying models for batch and real-time inference, and monitoring production solutions for drift, bias, latency, and security. The exam is scenario-heavy. You need to understand why a particular service or pattern is the right choice, not just what it does.
What's in these MLA-C01 practice exams
The free MLA-C01 practice exams cover every domain in the official exam guide:
- Data Preparation for ML (S3, Glue, Athena, DataBrew, Feature Store, Ground Truth, bias detection)
- ML Model Development (SageMaker built-in algorithms, Autopilot, JumpStart, hyperparameter tuning, evaluation metrics)
- Deployment and Orchestration of ML Workflows (real-time and batch inference, multi-model endpoints, SageMaker Pipelines, Step Functions, CI/CD)
- ML Solution Monitoring, Maintenance, and Security (Model Monitor, Clarify drift, IAM, KMS, VPC endpoints, CloudWatch alarms)
Every question includes a written explanation that covers the correct answer and why the distractors are wrong. The first set is completely free, so you can try it without an account or payment.
How to use these effectively
Start with the free set and read every explanation, even on questions you get right. The MLA-C01 leans on judgment calls between similar SageMaker features, like when to pick Asynchronous Inference over Batch Transform or when a multi-model endpoint beats one endpoint per model. Once you've worked through the free set, move into timed mode to practise pacing for the 130 minute real exam. Spend extra time on Pipelines, Model Monitor, Feature Store, and security patterns like VPC isolation and KMS encryption, since those topics show up across almost every domain.
