C. Create a single Amazon Simple Notification Service (Amazon SNS) topic and subscribe the Amazon SQS queues to the SNS topic. Configure SNS message filtering to publish messages to the proper SQS queue based on the quote type. Configure each backend application server to work its own SQS queue.

Answer is C. Same case-study is presented here: https://aws.amazon.com/getting-started/hands-on/filter-messages-published-to-topics/

B. Create multiple Amazon Simple Notification Service (Amazon SNS) topics and register Amazon SQS queues to their own SNS topic based on the quote type. Configure the web application to publish messages to the SNS topic queue. Configure each backend application server to work with its own SQS queue. This solution allows for separation of quotes by type using different SNS topics and SQS queues. The SNS topics ensure that messages are published to the corresponding SQS queues based on quote type, and SQS provides reliable and scalable message storage. Each backend application server can then consume messages from its designated SQS queue, process them accordingly, and ensure that quotes are responded to within the required time frame. Additionally, this setup is relatively simple to set up and maintain compared to the other options provided.

Ans is C

Should be C

C for me since the process needed is not real time. so SNS will do.

Unless there is a phrase from case-study: "and an analytics system that needs to process all quote requests" it doesn't seems to be a big difference between single topic and multiple topics. IMHO multiple is prefferable if you don't need all the messages

C is ans

What does it has to do with Kinesis? You can't register to a SNS topic but subscribe to a topic, right? I think it should be C.

Right and is C - to configure SNS message filtering to publish messages to proper SQS queue. Not sure why they have mentioned as D.

C for sure, why the answer is wrong? To use Kinesis, you need to have key words such as big data, real-time. This a classic example of SNS+SQS fan out architecture.

Ans looks like: C SNS capable of message filter (key word) and same insurance quote type filtering given in below official doc https://aws.amazon.com/getting-started/hands-on/filter-messages-published-to-topics/

The answer is C.

To me the answer B makes more sense.
