MLA-C01 Practice Question: ML Solution Monitoring, Maintenance, and Security
A company wants to automate remediation when a SageMaker endpoint's latency exceeds a threshold for more than 5 minutes. The team needs to be notified and a Lambda function should be invoked to scale up the endpoint. Which combination of services should be used?
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 topic → Lambda function
CloudWatch Alarms monitor metrics and trigger actions. SNS can notify and invoke Lambda for automated remediation. EventBridge is used for scheduled events, not direct alarm actions.
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 topic → Lambda function
Why this is correct
CloudWatch Alarms can publish to an SNS topic which can invoke a Lambda function for automated scaling.
- ✗
EventBridge rule to trigger Lambda
Why it's wrong here
EventBridge rules can schedule events but cannot directly react to CloudWatch alarm state changes; CloudWatch Alarms are needed.
- ✗
CloudWatch Logs subscription filter → Lambda function
Why it's wrong here
Logs subscription filters process log streams; for metric-based alarms, CloudWatch Alarms are the correct trigger.
- ✗
SageMaker Model Monitor → Lambda function
Why it's wrong here
SageMaker Model Monitor detects drift and outputs violations to CloudWatch, but it does not directly trigger Lambda on latency thresholds.
