Answer: Use an Amazon SQS queue subscribed to the SNS topic., Adapt Lambda to process messages from an SQS queue.
To ensure that the Lambda function ingests all data reliably, using an Amazon SQS queue subscribed to the SNS topic will allow messages to be queued and retried automatically if there are transient failures, such as network connectivity issues. Modifying the Lambda function to read from an Amazon SQS queue ensures that the function processes all messages that it might have missed during these failures. Therefore, the correct answers are B and E.
