MLS-C01 Practice Question: Machine Learning Implementation and Operations
A team is using Amazon SageMaker Autopilot to automatically build models. The dataset has 50 features and 1 million rows. After training, Autopilot generates multiple candidates. The team wants to deploy the model with the highest accuracy. What is the best practice to select and deploy the model?
⚠ Common exam trap
The trap here is that candidates may overthink the process and assume manual review or additional tuning is required, when in fact Autopilot is designed to automate model selection and deployment based on the leaderboard.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Deploy the candidate with the highest objective metric value from the Autopilot leaderboard
Amazon SageMaker Autopilot automatically generates a leaderboard ranking candidate models by their objective metric (e.g., accuracy, F1, AUC). The highest-ranked candidate represents the best-performing model based on the validation data, and deploying it directly is the recommended best practice. Autopilot handles preprocessing, algorithm selection, and hyperparameter tuning internally, so manual intervention is unnecessary.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Deploy all candidates behind a multi-model endpoint and route traffic based on request features
Why it's wrong here
Overly complex and not recommended.
- ✗
Select the model with the highest validation accuracy after performing additional hyperparameter tuning
Why it's wrong here
Autopilot already optimizes; extra tuning may overfit.
- ✗
Manually review each candidate's architecture and select the one with the simplest design
Why it's wrong here
Accuracy should be primary, not simplicity.
- ✓
Deploy the candidate with the highest objective metric value from the Autopilot leaderboard
Why this is correct
Autopilot ranks candidates by objective metric.
