Answer: Increase the message retention period, Attach a dead-letter queue (DLQ) to the SQS queue.
Option A is CORRECT because increasing the message retention period in Amazon SQS allows messages to remain in the queue for a longer duration before they expire. By extending the retention period (up to 14 days), the application has a longer time window to process the messages, thereby reducing the likelihood of message loss due to occasional application downtime. Option C is CORRECT because attaching a dead-letter queue (DLQ) to the SQS queue ensures that messages that cannot be processed successfully after a specified number of retries are moved to the DLQ. This helps preserve unprocessed messages rather than allowing them to expire in the main queue, enabling the application to analyze or reprocess the messages later, thereby minimizing data loss.

A
Increase the message retention period
B
Increase the visibility timeout.
C
Attach a dead-letter queue (DLQ) to the SQS queue.
