- A
Amazon SNS topics to send email or SMS.
SNS is used for sending notifications.
- B
Amazon EventBridge to trigger a notification.
Why wrong: EventBridge can trigger a target, but notification directly is typically through SNS.
- C
AWS Lambda to process the drift and send an email via SES.
Why wrong: Lambda can be used, but the question asks for a service pair that 'can be used together'; CloudWatch+SNS is more direct.
- D
Amazon SQS to queue the notification.
Why wrong: SQS is a queue, not a notification delivery service.
- E
Amazon CloudWatch Alarms set on the drift metric.
CloudWatch Alarm can monitor the drift metric and invoke an action.

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 uses SageMaker Model Monitor to detect drift. They want to receive notifications when drift is detected. Which TWO services can be used together to send notifications? (Choose TWO.)
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
✓
Amazon SNS topics to send email or SMS.
Amazon SNS (Simple Notification Service) is the correct service to send notifications via email or SMS when drift is detected. Amazon CloudWatch Alarms can be set on the drift metrics emitted by SageMaker Model Monitor (e.g., `feature_baseline_drift` or `data_quality_drift`), and when the alarm state changes to ALARM, it can trigger an SNS topic to deliver the notification. This combination provides a fully managed, serverless notification pipeline without custom code.
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 overcomplicate the solution by choosing Lambda or EventBridge, not realizing that CloudWatch Alarms can directly trigger SNS topics for drift metrics emitted by SageMaker Model Monitor, making those extra services unnecessary.
Detailed technical explanation
How to think about this question
SageMaker Model Monitor publishes drift metrics to CloudWatch automatically under the namespace `/aws/sagemaker/ModelMonitor`. You can create a CloudWatch Alarm on the `Drift` metric (e.g., `feature_baseline_drift` or `data_quality_drift`) with a threshold (e.g., 0.1 for statistical distance). When the alarm enters the ALARM state, it publishes to an SNS topic, which can fan out to email, SMS, or other endpoints. This pattern is recommended by AWS for drift notifications because it uses native integrations and avoids custom code, ensuring reliability and low latency.
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
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
