MLA-C01 Practice Question: A machine learning engineer is setting up…
A machine learning engineer is setting up automated retraining for a model using SageMaker Pipelines. The pipeline should trigger when a data drift alert is received from Model Monitor. Which event source should the engineer use to initiate the pipeline?
⚠ Common exam trap
Many exam-takers confuse S3 event notifications (which are for object-level events) with the structured, high-level alerts emitted by Model Monitor, leading them to choose Option C instead of the correct EventBridge integration.

Correct answer & explanation
✓
Amazon CloudWatch Events (Amazon EventBridge) rule that captures Model Monitor outcome.
Amazon EventBridge (formerly CloudWatch Events) is the native AWS service for reacting to state changes in AWS resources. SageMaker Model Monitor publishes data drift alerts as events to EventBridge, so a rule can be configured to match those specific events and trigger the SageMaker Pipeline execution as a target. This provides a fully managed, event-driven architecture without polling or custom integrations.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Amazon CloudWatch Events (Amazon EventBridge) rule that captures Model Monitor outcome.
Why this is correct
Model Monitor publishes violation events to EventBridge, which can trigger a pipeline execution reliably.
- ✗
AWS Lambda function that polls CloudWatch logs.
Why it's wrong here
Polling is inefficient and introduces latency; event-driven approach is preferred.
- ✗
S3 event notification on the monitoring output bucket.
Why it's wrong here
S3 events fire when new monitoring results are written, but they do not indicate drift severity; over-triggering could occur.
- ✗
SageMaker model monitor webhook.
Why it's wrong here
SageMaker Model Monitor does not provide a webhook mechanism.
