Route 53 API Gateway Lambda CloudFront S3 RDS Config DMS

题目

A company runs its sales reporting application in an AWS Region in the United States. The application uses an Amazon API Gateway Regional API and AWS Lambda functions to generate on-demand reports from data in an Amazon RDS for MySQL database. The frontend of the application is hosted on Amazon S3 and is accessed by users through an Amazon CloudFront distribution. The company is using Amazon Route 53 as the DNS service for the domain. Route 53 is configured with a simple routing policy to route traffic to the API Gateway API. In the next 6 months, the company plans to expand operations to Europe. More than 90% of the database traffic is read-only traffic. The company has already deployed an API Gateway API and Lambda functions in the new Region. A solutions architect must design a solution that minimizes latency for users who download reports. Which solution will meet these requirements? API。

中文翻译:
一家公司在美国的 AWS 区域运行其销售报告应用程序。该应用程序使用 Amazon API Gateway Regional API 和 AWS Lambda 函数根据 Amazon RDS for MySQL 数据库中的数据生成按需报告。该应用程序的前端托管在 Amazon S3 上,用户可以通过 Amazon CloudFront 发行版进行访问。该公司使用 Amazon Route 53 作为域的 DNS 服务。 Route 53 配置了一个简单的路由策略,用于将流量路由到 API Gateway API。未来6个月内,该公司计划将业务扩展至欧洲。超过90%的数据库流量是只读流量。该公司已经在新区域部署了 API Gateway API 和 Lambda 函数。解决方案架构师必须设计一种解决方案,最大限度地减少下载报告的用户的延迟。哪种解决方案可以满足这些要求? API。

选项

A. Use an AWS Database Migration Service (AWS DMS) task with full load to replicate the primary database in the original Region to the database in the new Region. Change the Route 53 record to latency-based routing to connect to the API Gateway API.

中文翻译:
使用满负载的 AWS Database Migration Service (AWS DMS) 任务将原始区域中的主数据库复制到新区域中的数据库。将 Route 53 记录更改为基于延迟的路由以连接到 API Gateway API。

B. Use an AWS Database Migration Service (AWS DMS) task with full load plus change data capture (CDC) to replicate the primary database in the original Region to the database in the new Region. Change the Route 53 record to geolocation routing to connect to the API Gateway API.

中文翻译:
使用具有完全加载和更改数据捕获 (CDC) 功能的 AWS Database Migration Service (AWS DMS) 任务将原始区域中的主数据库复制到新区域中的数据库。将 Route 53 记录更改为地理位置路由以连接到 API Gateway API。

C. Configure a cross-Region read replica for the RDS database in the new Region Change the Route 53 record to latency-based routing to connect to the API Gateway API.

中文翻译:
为新区域中的 RDS 数据库配置跨区域只读副本 将 Route 53 记录更改为基于延迟的路由以连接到 API Gateway API。

D. Configure a cross-Region read replica for the RDS database in the new Region. Change the Route 53 record to geolocation routing to connect to the API Gateway API.

中文翻译:
为新Region中的RDS数据库配置跨Region只读副本。将 Route 53 记录更改为地理位置路由以连接到 API Gateway API。

答案

C

解析

正确答案:C 解析: 本题应选择 C。 正确选项: C. 为新区域中的 RDS 数据库配置跨区域只读副本 将 Route 53 记录更改为基于延迟的路由以连接到 API Gateway API。 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、合规要求等。本题相关考点主要包括:Route 53、API ...
