SAP-C02 第 292 题
题目
A company needs to migrate an on-premises SFTP site to AWS. The SFTP site currently runs on a Linux VM. Uploaded files are made available to downstream applications through an NFS share. As part of the migration to AWS, a solutions architect must implement high availability. The solution must provide external vendors with a set of static public IP addresses that the vendors can allow. The company has set up an AWS Direct Connect connection between its on-premises data center and its VPC. Which solution will meet these requirements with the LEAST operational overhead?

一家公司需要将本地 SFTP 站点迁移到 AWS。 SFTP 站点当前在 Linux VM 上运行。上传的文件可通过 NFS 共享供下游应用程序使用。作为迁移到 AWS 的一部分，解决方案架构师必须实现高可用性。该解决方案必须向外部供应商提供一组供应商允许的静态公共IP 地址。该公司已在其本地数据中心与其 VPC 之间建立了 AWS Direct Connect 连接。哪种解决方案能够以最少的运营开销满足这些要求？
选项
A. Create an AWS Transfer Family server. Configure an internet-facing VPC endpoint for the Transfer Family server. Specify an Elastic IP address for each subnet. Configure the Transfer Family server to place files into an Amazon Elastic File System (Amazon EFS) file system that is deployed across multiple Availability Zones. Modify the configuration on the downstream applications that access the existing NFS share to mount the EFS endpoint instead.

创建 AWS Transfer Family 服务器。为 Transfer Family 服务器配置面向互联网的 VPC 终端节点。为每个子网指定弹性 IP 地址。配置 Transfer Family 服务器以将文件放入跨多个可用区部署的 Amazon Elastic File System (Amazon EFS) 文件系统中。修改访问现有 NFS 共享的下游应用程序的配置以挂载 EFS 端点。
B. Create an AWS Transfer Family server. Configure a publicly accessible endpoint for the Transfer Family server. Configure the Transfer Family server to place files into an Amazon Elastic File System (Amazon EFS) file system that is deployed across multiple Availability Zones. Modify the configuration on the downstream applications that access the existing NFS share to mount the EFS endpoint instead.

创建 AWS Transfer Family 服务器。为 Transfer Family 服务器配置可公开访问的端点。配置 Transfer Family 服务器以将文件放入跨多个可用区部署的 Amazon Elastic File System (Amazon EFS) 文件系统中。修改访问现有 NFS 共享的下游应用程序的配置以挂载 EFS 端点。
C. Use AWS Application Migration Service to migrate the existing Linux VM to an Amazon EC2 instance. Assign an Elastic IP address to the EC2 instance. Mount an Amazon Elastic File System (Amazon EFS) file system to the EC2 instance. Configure the SFTP server to place files in the EFS file system. Modify the configuration on the downstream applications that access the existing NFS share to mount the EFS endpoint instead.

使用 AWS Application Migration Service 将现有 Linux VM 迁移到 Amazon EC2 实例。为 EC2 实例分配弹性 IP 地址。将 Amazon Elastic File System (Amazon EFS) 文件系统挂载到 EC2 实例。配置SFTP服务器以将文件放置在EFS文件系统中。修改访问现有 NFS 共享的下游应用程序的配置以挂载 EFS 端点。
D. Use AWS Application Migration Service to migrate the existing Linux VM to an AWS Transfer Family server. Configure a publicly accessible endpoint for the Transfer Family server. Configure the Transfer Family server to place files into an Amazon FSx for Lustre file system that is deployed across multiple Availability Zones. Modify the configuration on the downstream applications that access the existing NFS share to mount the FSx for Lustre endpoint instead.
