Exhibit
Worker log excerpt: 2026-04-28T09:02:11Z messageId=7f31 receiveCount=1 status=ValidationError 2026-04-28T09:03:14Z messageId=7f31 receiveCount=2 status=ValidationError 2026-04-28T09:04:17Z messageId=7f31 receiveCount=3 status=ValidationError Queue metric: ApproximateNumberOfMessagesNotVisible keeps increasing
Based on the exhibit, some SQS messages fail validation repeatedly and continue consuming worker time. What change best prevents the bad messages from being retried forever?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Distractor review
Increase the visibility timeout so each message has more time to finish processing.
A longer visibility timeout may help slow processing, but it does not stop poison messages from being retried after repeated failures.
B
Best answer
Configure a dead-letter queue and a redrive policy for messages that exceed the retry limit.
A dead-letter queue captures messages that fail repeatedly after a defined receive count. The main queue can keep processing healthy messages, while the poison messages are isolated for later inspection and remediation.
C
Distractor review
Replace the queue with an Amazon SNS topic so failed messages will not be retried.
SNS is a publish-subscribe service, not a retry-failure mechanism for already queued messages. It does not solve repeated processing of the same bad payload.
D
Distractor review
Increase the number of workers so the queue drains faster during peak load.
More workers can improve throughput, but they do not prevent the same malformed message from failing over and over again.
Common exam trap
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.
Technical deep dive
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.

FAQ
Questions learners often ask
What does this SAA-C03 question test?
Read the scenario before looking for a memorised answer.
What is the correct answer to this question?
The correct answer is: Configure a dead-letter queue and a redrive policy for messages that exceed the retry limit. — A dead-letter queue is the standard way to isolate poison messages in SQS. When the message exceeds the configured receive count, SQS moves it to the DLQ instead of returning it to workers again and again. That protects worker capacity, makes failures visible, and keeps the healthy messages flowing through the main queue. Option A only changes how long a message stays invisible after receive; it does not stop repeated failures. Option C uses the wrong service model and does not solve queue redelivery. Option D may increase throughput, but it can also waste more compute on the same bad payload.
