Exam AWS Certified Solutions Architect - Associate SAA-C03 topic 1 question 311 discussion

Quote types need to be separated: SNS message filtering can be used to publish messages to the appropriate SQS queue based on the quote type, ensuring that quotes are separated by type. Quotes must be responded to within 24 hours and must not get lost: SQS provides reliable and scalable queuing for messages, ensuring that quotes will not get lost and can be processed in a timely manner. Additionally, each backend application server can use its own SQS queue, ensuring that quotes are processed efficiently without any delay. Operational efficiency and minimizing maintenance: Using a single SNS topic and multiple SQS queues is a scalable and cost-effective approach, which can help to maximize operational efficiency and minimize maintenance. Additionally, SNS and SQS are fully managed services, which means that the company will not need to worry about maintenance tasks such as software updates, hardware upgrades, or scaling the infrastructure.

C is the best option

SQS + SNS = fanout

Option C would be the most suitable solution to meet the requirements while maximizing operational efficiency and minimizing maintenance. Explanation: Amazon SNS (Simple Notification Service) allows for the creation of a single topic to which multiple subscribers can be attached. In this scenario, each quote type can be considered a subscriber. Amazon SQS (Simple Queue Service) queues can be subscribed to the SNS topic, and SNS message filtering can be used to direct messages to the appropriate SQS queue based on the quote type. This setup ensures that quotes are separated by quote type and that they are not lost. Each backend application server can then poll its own SQS queue to retrieve and process messages. This architecture is efficient, scalable, and requires minimal maintenance, as it leverages managed AWS services without the need for complex custom code or infrastructure setup.

I originally went for D due to searching requirements but Open Search is for analytics and logs and nothing to do with data coming from streams as in this question.

Keyword is "..and must not get lost" = SQS

Create a single SNS topic Subscribe separate SQS queues per quote type Use SNS message filtering to send messages to proper queue Backend servers poll their respective SQS queue The key points: Quote requests must be processed within 24 hrs without loss Need to maximize efficiency and minimize maintenance Requests separated by quote type

This wrong answers from examtopic are getting me so frustrated. Which one is the correct answer then?

This is the SNS fan-out technique where you will have one SNS service to many SQS services https://docs.aws.amazon.com/sns/latest/dg/sns-sqs-as-subscriber.html
