Topic #: 1

[All AWS Certified Solutions Architect - Associate SAA-C02 Questions]

A company has two applications: a sender application that sends messages with payloads to be processed and a processing application intended to receive messages with payloads. The company wants to implement an AWS service to handle messages between the two applications. The sender application can send about 1,000 messages each hour. The messages may take up to 2 days to be processed. If the messages fail to process, they must be retained so that they do not impact the processing of any remaining messages.
Which solution meets these requirements and is the MOST operationally efficient?

A. Set up an Amazon EC2 instance running a Redis database. Configure both applications to use the instance. Store, process, and delete the messages, respectively.
B. Use an Amazon Kinesis data stream to receive the messages from the sender application. Integrate the processing application with the Kinesis Client Library (KCL).
C. Integrate the sender and processor applications with an Amazon Simple Queue Service (Amazon SQS) queue. Configure a dead-letter queue to collect the messages that failed to process.
D. Subscribe the processing application to an Amazon Simple Notification Service (Amazon SNS) topic to receive notifications to process. Integrate the sender application to write to the SNS topic.

I have doubts about SQS answer What about "The messages may take up to 2 days to be processed"? maximum SQS Visibility timeout : 12 h retention period could be up to 14 days, but then the messages cuuld be processed several times Can anyone clarify this point?

paraphrase " If the messages fail to process, they must be retained so that they do not impact the processing of any remaining messages." >> DLQ --> leads to Answer (C).

Visibility timeout is processing time. the message may take up to 2 days to be processed I think it means retention time 2 days but not processing time two days.

C for correct https://docs.aws.amazon.com/sns/latest/dg/sns-dead-letter-queues.html: "A dead-letter queue is an Amazon SQS queue that an Amazon SNS subscription can target for messages that can't be delivered to subscribers successfully"
