[All AWS Certified Solutions Architect - Professional SAP-C02 Questions]

A company wants to refactor its retail ordering web application that currently has a load-balanced Amazon EC2 instance fleet for web hosting, database API services, and business logic. The company needs to create a decoupled, scalable architecture with a mechanism for retaining failed orders while also minimizing operational costs.

Which solution will meet these requirements?

  • A. Use Amazon S3 for web hosting with Amazon API Gateway for database API services. Use Amazon Simple Queue Service (Amazon SQS) for order queuing. Use Amazon Elastic Container Service (Amazon ECS) for business logic with Amazon SQS long polling for retaining failed orders.
  • B. Use AWS Elastic Beanstalk for web hosting with Amazon API Gateway for database API services. Use Amazon MQ for order queuing. Use AWS Step Functions for business logic with Amazon S3 Glacier Deep Archive for retaining failed orders.
  • C. Use Amazon S3 for web hosting with AWS AppSync for database API services. Use Amazon Simple Queue Service (Amazon SQS) for order queuing. Use AWS Lambda for business logic with an Amazon SQS dead-letter queue for retaining failed orders.
  • D. Use Amazon Lightsail for web hosting with AWS AppSync for database API services. Use Amazon Simple Email Service (Amazon SES) for order queuing. Use Amazon Elastic Kubernetes Service (Amazon EKS) for business logic with Amazon OpenSearch Service for retaining failed orders.

Option C combines Amazon S3 for web hosting, AWS AppSync for database API services, and AWS Lambda for business logic. This combination provides a decoupled and scalable architecture. Using Amazon SQS for order queuing ensures reliable message delivery, and utilizing an SQS dead-letter queue allows for retaining failed orders. This solution meets the requirements of the scenario while minimizing operational costs

Checking a bit more for AWS AppSync - AWS AppSync enables developers to connect their applications and services to data and events with secure, serverless and high-performing GraphQL and Pub/Sub APIs. GraphQL is an open-source query language that describes how a client should request information through an API I don't believe this is the intent of the exercise here by saying "Database API"

SQS long polling does not solve "retaining failed orders" - it's dead-letter queue's responsibility.
