MLA-C01 Practice Question: ML Solution Monitoring, Maintenance, and Security
An ML engineer wants to be notified when the average inference latency of a SageMaker endpoint exceeds 500 ms for 2 consecutive evaluation periods. Which AWS service combination should they use?
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
✓
CloudWatch Alarm + SNS
CloudWatch collects the 'Latency' metric from SageMaker endpoints. A CloudWatch Alarm can be set on this metric with a threshold of 500 ms for 2 consecutive periods. SNS then sends notification (email, SMS, etc.). Lambda is for automated remediation, not required for notification only.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
CloudWatch Alarm + SNS
Why this is correct
CloudWatch Alarm triggers on the Latency metric and publishes to SNS for notification.
- ✗
SageMaker Model Monitor + SNS
Why it's wrong here
Model Monitor is for data/model quality, not latency metrics.
- ✗
EventBridge + Lambda
Why it's wrong here
EventBridge is for scheduling or event-driven workflows, not direct metric-based alarms.
- ✗
SageMaker Clarify + SNS
Why it's wrong here
SageMaker Clarify is for bias and explainability, not latency monitoring.
