SAP-C02 第 395 题

API Gateway Lambda Aurora Config

题目

A company hosts a software as a service (SaaS) solution on AWS. The solution has an Amazon API Gateway API that serves an HTTPS endpoint. The API uses AWS Lambda functions for compute. The Lambda functions store data in an Amazon Aurora Serverless v1 database. The company used the AWS Serverless Application Model (AWS SAM) to deploy the solution. The solution extends across multiple Availability Zones and has no disaster recovery (DR) plan. A solutions architect must design a DR strategy that can recover the solution in another AWS Region. The solution has an RTO of 5 minutes and an RPO of 1 minute. What should the solutions architect do to meet these requirements?

中文翻译:
一家公司在 AWS 上托管软件即服务 (SaaS) 解决方案。该解决方案有一个为 HTTPS 终端节点提供服务的 Amazon API Gateway API。该 API 使用 AWS Lambda 函数进行计算。 Lambda 函数将数据存储在 Amazon Aurora Serverless v1 数据库中。该公司使用 AWS 无服务器应用程序模型 (AWS SAM) 来部署该解决方案。该解决方案跨越多个可用区,并且没有灾难恢复 (DR) 计划。解决方案架构师必须设计一个可以在另一个 AWS 区域恢复解决方案的灾难恢复策略。该解决方案的 RTO 为 5 分钟,RPO 为 1 分钟。解决方案架构师应该怎样做才能满足这些要求?

选项

A. Create a read replica of the Aurora Serverless v1 database in the target Region. Use AWS SAM to create a runbook to deploy the solution to the target Region. Promote the read replica to primary in case of disaster.

中文翻译:
在目标区域中创建 Aurora Serverless v1 数据库的只读副本。使用 AWS SAM 创建 Runbook 以将解决方案部署到目标区域。在发生灾难时将只读副本提升为主副本。

B. Change the Aurora Serverless v1 database to a standard Aurora MySQL global database that extends across the source Region and the target Region. Use AWS SAM to create a runbook to deploy the solution to the target Region.

中文翻译:
将 Aurora Serverless v1 数据库更改为跨源区域和目标区域扩展的标准 Aurora MySQL 全局数据库。使用 AWS SAM 创建 Runbook 以将解决方案部署到目标区域。

C. Create an Aurora Serverless v1 DB cluster that has multiple writer instances in the target Region. Launch the solution in the target Region. Configure the two Regional solutions to work in an active-passive configuration.

中文翻译:
创建在目标区域中具有多个写入器实例的 Aurora Serverless v1 数据库集群。在目标区域启动解决方案。将两个区域解决方案配置为在主动-被动配置中工作。

D. Change the Aurora Serverless v1 database to a standard Aurora MySQL global database that extends across the source Region and the target Region. Launch the solution in the target Region. Configure the two Regional solutions to work in an active-passive configuration.

中文翻译:
将 Aurora Serverless v1 数据库更改为跨源区域和目标区域扩展的标准 Aurora MySQL 全局数据库。在目标区域启动解决方案。将两个区域解决方案配置为在主动-被动配置中工作。

答案

D

解析

正确答案:D 解析: 本题应选择 D。 正确选项: D. 将 Aurora Serverless v1 数据库更改为跨源区域和目标区域扩展的标准 Aurora MySQL 全局数据库。在目标区域启动解决方案。将两个区域解决方案配置为在主动-被动配置中工作。 选择理由: 该选项最直接地满足题干中的关键约束。做 SAP-C02 题目时,需要同时对照题干里的限定词,例如最高性能、最低运维开销、成本效益、可靠性、可扩展性、安全性、RTO/RPO...
