SAP-C02 第 296 题
题目
A company implements a containerized application by using Amazon Elastic Container Service (Amazon ECS) and Amazon API Gateway The application data is stored in Amazon Aurora databases and Amazon DynamoDB databases. The company automates infrastructure provisioning by using AWS CloudFormation. The company automates application deployment by using AWS CodePipeline. A solutions architect needs to implement a disaster recovery (DR) strategy that meets an RPO of 2 hours and an RTO of 4 hours. Which solution will meet these requirements MOST cost-effectively?

一家公司使用 Amazon Elastic Container Service (Amazon ECS) 和 Amazon API Gateway 实施容器化应用程序。应用程序数据存储在 Amazon Aurora 数据库和 Amazon DynamoDB 数据库中。该公司使用 AWS CloudFormation 自动化基础设施配置。该公司使用 AWS CodePipeline 自动化应用程序部署。解决方案架构师需要实施满足 2 小时 RPO 和 4 小时 RTO 的灾难恢复 (DR) 策略。哪种解决方案能够最具成本效益地满足这些要求?
选项
A. Set up an Aurora global database and DynamoDB global tables to replicate the databases to a secondary AWS Region. In the primary Region and in the secondary Region, configure an API Gateway API with a Regional endpoint. Implement Amazon CloudFront with origin failover to route traffic to the secondary Region during a DR scenario.

设置 Aurora 全局数据库和 DynamoDB 全局表以将数据库复制到辅助 AWS 区域。在主要区域和次要区域中,使用区域终端节点配置 API Gateway API。实施具有源故障转移功能的 Amazon CloudFront,以在灾难恢复场景期间将流量路由到次要区域。
B. Use AWS Database Migration Service (AWS DMS), Amazon EventBridge, and AWS Lambda to replicate the Aurora databases to a secondary AWS Region. Use DynamoDB Streams, EventBridge. and Lambda to replicate the DynamoDB databases to the secondary Region. In the primary Region and in the secondary Region, configure an API Gateway API with a Regional endpoint. Implement Amazon Route 53 failover routing to switch traffic from the primary Region to the secondary Region.
