MLA-C01 Practice Question: ML Solution Monitoring, Maintenance, and Security
A machine learning team deploys a fraud detection model on a SageMaker endpoint. The model's predictions are used in real-time. The team wants to monitor for data drift by comparing incoming data distributions against a baseline created from the training data. Which SageMaker capability should they use?
⚠ Common exam trap
Candidates often confuse 'data drift' (input distribution changes) with 'model quality drift' (prediction performance changes), leading them to select Model Quality Monitor instead of Data Quality Monitor.

Correct answer & explanation
✓
SageMaker Model Monitor - Data Quality Monitor
SageMaker Model Monitor's Data Quality Monitor is specifically designed to detect data drift by comparing the statistical distribution of incoming inference data against a baseline computed from the training dataset. This capability tracks metrics like mean, variance, and quantiles for each feature, alerting when significant deviations occur. For a fraud detection model requiring real-time monitoring of input distributions, this is the correct choice.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
SageMaker Model Monitor - Model Quality Monitor
Why it's wrong here
Requires ground truth labels which are not available in real time for fraud detection.
- ✓
SageMaker Model Monitor - Data Quality Monitor
Why this is correct
Correctly monitors statistical and schema drift against a training baseline.
- ✗
SageMaker Model Monitor - Feature Attribution Drift Monitor
Why it's wrong here
Monitors changes in SHAP feature importance, not data distribution.
- ✗
SageMaker Model Monitor - Bias Drift Monitor
Why it's wrong here
Monitors bias metrics, not data distribution drift.
