SAP-C02 第 278 题
题目
A company plans to deploy a new private intranet service on Amazon EC2 instances inside a VPC. An AWS Site-to-Site VPN connects the VPC to the company's on-premises network. The new service must communicate with existing on-premises services. The on-premises services are accessible through the use of hostnames that reside in the company.example DNS zone. This DNS zone is wholly hosted on premises and is available only on the company's private network. A solutions architect must ensure that the new service can resolve hostnames on the company.example domain to integrate with existing services. Which solution meets these requirements?

一家公司计划在 VPC 内的 Amazon EC2 实例上部署新的私有 Intranet 服务。 AWS 站点到站点 VPN 将 VPC 连接到公司的本地网络。新服务必须与现有的本地服务进行通信。可通过使用驻留在 company.example DNS 区域中的主机名来访问本地服务。该 DNS 区域完全托管在本地,并且仅在公司的专用网络上可用。解决方案架构师必须确保新服务可以解析 company.example 域上的主机名,以与现有服务集成。哪种解决方案满足这些要求?
选项
A. Create an empty private zone in Amazon Route 53 for company.example. Add an additional NS record to the company's on- premises company.example zone that points to the authoritative name servers for the new private zone in Route 53.

在 Amazon Route 53 中为 company.example 创建一个空的私有区域。将额外的 NS 记录添加到公司的本地 company.example 区域,该区域指向 Route 53 中新私有区域的权威名称服务器。
B. Turn on DNS hostnames for the VPC. Configure a new outbound endpoint with Amazon Route 53 Resolver. Create a Resolver rule to forward requests for company.example to the on-premises name servers.
中文翻译:
为 VPC 打开 DNS 主机名。使用 Amazon Route 53 Resolver 配置新的出站终端节点。创建解析程序规则以将对 company.example 的请求转发到本地名称服务器。
C. Turn on DNS hostnames for the VPConfigure a new inbound resolver endpoint with Amazon Route 53 Resolver. Configur&the on-premises DNS server to forward requests for company.example to the new resolver.
中文翻译:
为 VP 打开 DNS 主机名使用 Amazon Route 53 解析器配置新的入站解析器终端节点。配置本地 DNS 服务器,将对 company.example 的请求转发到新解析器。
D. Use AWS Systems Manager to configure a run document that will install a hosts file that contains any required hostnames. Use an Amazon EventBridge rule to run the document when an instance is entering the running state.
中文翻译:
使用 AWS Systems Manager 配置运行文档,该文档将安装包含任何所需主机名的主机文件。当实例进入运行状态时,使用 Amazon EventBridge 规则运行文档。
