- A
AWS Lambda
Why wrong: Lambda can be triggered but EventBridge is the service that routes events to targets.
- B
Amazon CloudWatch Events (EventBridge)
Correct. EventBridge can capture Model Registry events and trigger downstream actions like CodePipeline.
- C
Amazon S3 Events
Why wrong: S3 events are triggered by S3 actions, not Model Registry changes.
- D
Amazon SNS
Why wrong: SNS is a notification service; it can be a target but is not the primary trigger service.
- E
AWS Config
Why wrong: AWS Config evaluates resource compliance, not event-driven triggers.

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. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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 the deployment of a SageMaker model into production whenever a new model version is approved in the Model Registry. Which service can be used to trigger the deployment pipeline?
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 CloudWatch Events (EventBridge)
Amazon EventBridge (formerly CloudWatch Events) can detect state changes in SageMaker Model Registry, such as when a model version is approved. It can then trigger a target like AWS CodePipeline or a Lambda function to automate the deployment pipeline, making it the correct choice for event-driven automation of model deployment.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

AWS Lambda
Why it's wrong here

Amazon S3 Events
Why it's wrong here
S3 events are triggered by S3 actions, not Model Registry changes.
- ✗
Amazon SNS
Why it's wrong here
SNS is a notification service; it can be a target but is not the primary trigger service.
- ✗
AWS Config
Why it's wrong here
AWS Config evaluates resource compliance, not event-driven triggers.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse the event source (SageMaker Model Registry) with the trigger mechanism (EventBridge), mistakenly selecting Lambda or SNS as the trigger service instead of recognizing EventBridge as the event bus that detects and routes the approval event.
Detailed technical explanation
How to think about this question
Under the hood, SageMaker Model Registry emits events to EventBridge when a model version's status changes (e.g., Approved, Rejected). EventBridge uses a default event bus and allows you to define rules with event patterns matching the 'SageMaker Model Package' source. This enables seamless integration with targets like CodePipeline, Step Functions, or Lambda, ensuring the deployment pipeline runs only on approved versions. In a real-world scenario, this pattern is critical for MLOps where manual approval gates must trigger automated CI/CD without polling.
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 media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
