AWS SAA-C03 · Question 31 · Domain 2.3: Decoupling Mechanisms
An e-commerce application uses an Amazon SQS queue to decouple the order ingestion web tier from the order processing backend tier. Occasionally, a malformed order message causes the backend processing application to crash. The message remains in the queue and causes a continuous loop of crashes. How can a solutions architect resolve this issue?
Answer options:
Increase the visibility timeout of the SQS queue.
Change the SQS queue to a FIFO queue.
Configure a Dead-Letter Queue (DLQ) for the SQS queue.
Use Amazon SNS instead of SQS.
