- A
CloudWatch Alarm → SNS topic → Lambda function
CloudWatch Alarms can publish to an SNS topic which can invoke a Lambda function for automated scaling.
- B
EventBridge rule to trigger Lambda
Why wrong: EventBridge rules can schedule events but cannot directly react to CloudWatch alarm state changes; CloudWatch Alarms are needed.
- C
CloudWatch Logs subscription filter → Lambda function
Why wrong: Logs subscription filters process log streams; for metric-based alarms, CloudWatch Alarms are the correct trigger.
- D
SageMaker Model Monitor → Lambda function
Why wrong: SageMaker Model Monitor detects drift and outputs violations to CloudWatch, but it does not directly trigger Lambda on latency thresholds.

MLA-C01 Practice Question: ML Solution Monitoring, Maintenance, and Security
This MLA-C01 practice question tests your understanding of ml solution monitoring, maintenance, and security. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
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.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Trap categories for this question
Command / output trap
SageMaker Model Monitor detects drift and outputs violations to CloudWatch, but it does not directly trigger Lambda on latency thresholds.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
An e-commerce site experiences heavy traffic on Black Friday and near-zero traffic during off-peak weeks. Rather than provisioning permanent large VMs, the team uses auto-scaling groups that add capacity automatically under load and reduce it overnight. Questions like this test whether you understand elasticity, availability zones, and cloud compute scaling patterns.
