SAP-C02 第 331 题
题目
A company is migrating an application to the AWS Cloud. The application runs in an on-premises data center and writes thousands of images into a mounted NFS file system each night. After the company migrates the application, the company will host the application on an Amazon EC2 instance with a mounted Amazon Elastic File System (Amazon EFS) file system. The company has established an AWS Direct Connect connection to AWS. Before the migration cutover, a solutions architect must build a process that will replicate the newly created on-premises images to the EFS file system. What is the MOST operationally efficient way to replicate the images?
中文翻译：
一家公司正在将应用程序迁移到 AWS 云。该应用程序在本地数据中心运行，每晚将数千个图像写入已安装的 NFS 文件系统中。在公司迁移应用程序后，公司将在安装有 Amazon Elastic File System (Amazon EFS) 文件系统的 Amazon EC2 实例上托管该应用程序。该公司已建立与 AWS 的 AWS Direct Connect 连接。在迁移转换之前，解决方案架构师必须构建一个流程，将新创建的本地映像复制到 EFS 文件系统。复制图像最有效的操作方法是什么？
选项
A. Configure a periodic process to run the aws s3 sync command from the on-premises file system to Amazon S3. Configure an AWS Lambda function to process event notifications from Amazon S3 and copy the images from Amazon S3 to the EFS file system.
中文翻译：
配置定期进程以运行从本地文件系统到 Amazon S3 的 aws s3sync 命令。配置 AWS Lambda 函数以处理来自 Amazon S3 的事件通知并将图像从 Amazon S3 复制到 EFS 文件系统。
B. Deploy an AWS Storage Gateway file gateway with an NFS mount point. Mount the file gateway file system on the on- premises server. Configure a process to periodically copy the images to the mount point.
中文翻译：
使用 NFS 挂载点部署 AWS Storage Gateway 文件网关。在本地服务器上挂载文件网关文件系统。配置进程以定期将映像复制到挂载点。
C. Deploy an AWS DataSync agent to an on-premises server that has access to the NFS file system. Send data over the Direct Connect connection to an S3 bucket by using a public VIF. Configure an AWS Lambda function to process event notifications from Amazon S3 and copy the images from Amazon S3 to the EFS file system.
中文翻译：
将 AWS DataSync 代理部署到有权访问 NFS 文件系统的本地服务器。使用公共 VIF 通过 Direct Connect 连接将数据发送到 S3 存储桶。配置 AWS Lambda 函数以处理来自 Amazon S3 的事件通知并将图像从 Amazon S3 复制到 EFS 文件系统。
D. Deploy an AWS DataSync agent to an on-premises server that has access to the NFS file system. Send data over the Direct Connect connection to an AWS PrivateLink interface VPC endpoint for Amazon EFS by using a private VIF. Configure a DataSync scheduled task to send the images to the EFS file system every 24 hours.
中文翻译：
将 AWS DataSync 代理部署到有权访问 NFS 文件系统的本地服务器。使用私有 VIF 通过 Direct Connect 连接将数据发送到 Amazon EFS 的 AWS PrivateLink 接口 VPC 终端节点。配置 DataSync 计划任务以每 24 小时将映像发送到 EFS 文件系统。
答案
D
