- A
Use the SageMaker Experiments Python SDK to create an experiment and log runs.
Directly supports experiment tracking.
- B
Enable SageMaker Model Monitor to track training metrics.
Why wrong: Model Monitor is for inference monitoring.
- C
Configure CloudWatch Logs to store experiment data.
Why wrong: CloudWatch is not designed for experiment tracking.
- D
Create a trial component in the experiment to log hyperparameters and metrics.
Trial components capture detailed run information.
- E
Enable SageMaker Studio to automatically capture experiments.
Why wrong: Not a required action; experiments can be tracked without Studio.

MLS-C01 Practice Question: Machine Learning Implementation and Operations
This MLS-C01 practice question tests your understanding of machine learning implementation and operations. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A data scientist is using SageMaker to train a model and wants to track experiments, including hyperparameters and metrics. Which TWO actions should the scientist take to set up experiment tracking? (Choose TWO.)
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
✓
Use the SageMaker Experiments Python SDK to create an experiment and log runs.
Option A is correct because the SageMaker Experiments Python SDK provides the primary interface for creating and managing experiments, allowing the data scientist to log runs, hyperparameters, and metrics in a structured way. This SDK directly integrates with SageMaker training jobs and notebook executions to capture experiment metadata.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The MLS-C01 exam often tests the distinction between monitoring (Model Monitor) and experiment tracking (Experiments SDK), and the trap here is that candidates confuse CloudWatch Logs or Model Monitor as valid tools for structured experiment metadata capture when they are not designed for that purpose.
Detailed technical explanation
How to think about this question
Under the hood, SageMaker Experiments uses a trial component as the core unit for logging hyperparameters and metrics; each training job or processing job creates a trial that contains multiple trial components. The SDK writes experiment data to the SageMaker backend, which stores it in a dedicated metadata store separate from CloudWatch Logs, enabling efficient querying and comparison across runs. In a real-world scenario, a data scientist might run hundreds of hyperparameter tuning jobs and use the Experiments SDK to compare validation accuracy across different learning rates and batch sizes without sifting through raw logs.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
