MLA-C01 Practice Question: ML Solution Monitoring, Maintenance, and Security
An ML engineer monitors a SageMaker endpoint for data drift. They set up SageMaker Model Monitor to compare inference data against a baseline created from the training dataset. The monitoring schedule runs daily and reports violations. Which monitoring type should be configured to detect if the distribution of a numerical feature in real-time inference data differs significantly from the training distribution?
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
✓
Data quality monitoring
SageMaker Model Monitor's data quality monitoring detects feature distribution drift (statistical drift) between baseline and live data. Model quality monitoring requires ground truth labels, bias drift monitors fairness metrics, and feature attribution drift monitors SHAP values.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Data quality monitoring
Why this is correct
Data quality monitoring evaluates statistical properties of features against a baseline and can detect numerical feature drift using metrics like mean, variance, or Kolmogorov-Smirnov test.
- ✗
Feature attribution drift monitoring
Why it's wrong here
Feature attribution drift monitors changes in SHAP values to detect concept drift, not raw feature distributions.
- ✗
Bias drift monitoring
Why it's wrong here
Bias drift monitoring tracks fairness metrics over time; it does not directly measure feature distribution changes.
- ✗
Model quality monitoring
Why it's wrong here
Model quality monitoring requires ground truth labels to compare predictions against actual outcomes; it does not check input feature distributions.
