- A
Use SQS dead-letter queue for failed training jobs
Why wrong: SQS DLQ is for queue messages, not Step Functions error handling.
- B
Add a Catch rule in the Step Functions state machine to invoke a Lambda alert function
Catch rules in Step Functions handle errors and route to fallback states.
- C
Configure SageMaker training job to publish to SNS on failure
Why wrong: SageMaker can publish to SNS, but Step Functions orchestration should handle evaluation failures as well.
- D
Use EventBridge to monitor the training job status
Why wrong: EventBridge can monitor, but the orchestration logic should be in Step Functions for error handling.

MLA-C01 Deployment and Orchestration of ML Workflows Practice Question
This MLA-C01 practice question tests your understanding of deployment and orchestration of ml workflows. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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.
An ML team uses AWS Step Functions to orchestrate a retraining pipeline triggered by EventBridge when new training data arrives. The pipeline includes a SageMaker training job and a model evaluation. If evaluation fails, the team wants to send an alert. How should they implement this?
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 a Catch rule in the Step Functions state machine to invoke a Lambda alert function
Step Functions supports error handling via Catch rules; a Catch on the training or evaluation task can transition to a Lambda function that sends an alert.
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.
- ✗
Use SQS dead-letter queue for failed training jobs
Why it's wrong here
SQS DLQ is for queue messages, not Step Functions error handling.
- ✓
Add a Catch rule in the Step Functions state machine to invoke a Lambda alert function
Why this is correct
Catch rules in Step Functions handle errors and route to fallback states.

Why it's wrong here
EventBridge can monitor, but the orchestration logic should be in Step Functions for error handling.
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.
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
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.
