- A
Add an SNS topic as the alarm action
SNS sends notifications to subscribers or triggers automation.
- B
Increase the endpoint instance count manually
Why wrong: Manual intervention is not automated remediation.
- C
Create a CloudWatch Alarm on the 5XXError metric
The alarm triggers when error count exceeds threshold.
- D
Enable detailed monitoring on the endpoint
Why wrong: Detailed monitoring provides more metrics but not remediation.
- E
Configure a Lambda function to restart the endpoint or scale out
Lambda can perform remediation steps like scaling or restarting.

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 machine learning team notices an increase in 5XXError count for a SageMaker endpoint. They want to set up automated remediation. Which THREE actions should they take? (Select THREE)
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
✓
Add an SNS topic as the alarm action
Option A is correct because adding an SNS topic as the alarm action enables automated notifications when the CloudWatch Alarm triggers on the 5XXError metric. This allows the team to receive alerts and trigger downstream remediation workflows, such as invoking a Lambda function, without manual intervention.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse enabling detailed monitoring (which only increases metric frequency) with automated remediation, or they mistakenly think manual scaling counts as automated remediation.
Detailed technical explanation
How to think about this question
SageMaker endpoints emit the 5XXError metric to CloudWatch, which counts HTTP 5XX responses from the model container. When creating a CloudWatch Alarm on this metric, you can configure an SNS topic as the alarm action, which can then invoke a Lambda function via an SNS subscription. The Lambda function can programmatically call the UpdateEndpointWeightsAndCapacities or UpdateEndpoint API to scale out the endpoint or restart the model container, providing automated remediation without manual steps.
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.
TExam Day Tips
- 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.
