SAP-C02 第 457 题
题目
A company has an application that analyzes and stores image data on premises. The application receives millions of new image files every day. Files are an average of 1 MB in size. The files are analyzed in batches of 1 GB. When the application analyzes a batch, the application zips the images together. The application then archives the images as a single file in an on-premises NFS server for long-term storage. The company has a Microsoft Hyper-V environment on premises and has compute capacity available. The company does not have storage capacity and wants to archive the images on AWS. The company needs the ability to retrieve archived data within 1 week of a request. The company has a 10 Gbps AWS Direct Connect connection between its on-premises data center and AWS. The company needs to set bandwidth limits and schedule archived images to be copied to AWS during non-business hours. Which solution will meet these requirements MOST cost-effectively?

一家公司有一个可以在本地分析和存储图像数据的应用程序。该应用程序每天都会收到数百万个新图像文件。文件的平均大小为 1 MB。文件以 1 GB 为单位进行批量分析。当应用程序分析一批图像时，应用程序会将图像压缩在一起。然后，应用程序将图像作为单个文件存档在本地 NFS 服务器中，以便长期存储。该公司拥有 Microsoft Hyper-V 环境并拥有可用的计算能力。该公司没有存储容量，希望将图像存档在 AWS 上。该公司需要能够在收到请求后 1 周内检索存档数据。该公司在其本地数据中心和 AWS 之间拥有 10 Gbps AWS Direct Connect 连接。该公司需要设置带宽限制并安排在非工作时间将存档图像复制到 AWS。哪种解决方案能够最具成本效益地满足这些要求？
选项
A. Deploy an AWS DataSync agent on a new GPU-based Amazon EC2 instance. Configure the DataSync agent to copy the batch of files from the NFS on-premises server to Amazon S3 Glacier Instant Retrieval. After the successful copy, delete the data from the on-premises storage.
中文翻译：
在新的基于 GPU 的 Amazon EC2 实例上部署 AWS DataSync 代理。配置 DataSync 代理以将批量文件从 NFS 本地服务器复制到 Amazon S3 Glacier Instant Retrieval。复制成功后，删除本地存储中的数据。
B. Deploy an AWS DataSync agent as a Hyper-V VM on premises. Configure the DataSync agent to copy the batch of files from the NFS on-premises server to Amazon S3 Glacier Deep Archive. After the successful copy, delete the data from the on- premises storage.
中文翻译：
将 AWS DataSync 代理部署为本地 Hyper-V 虚拟机。配置 DataSync 代理以将批量文件从 NFS 本地服务器复制到 Amazon S3 Glacier Deep Archive。复制成功后，删除本地存储中的数据。
C. Deploy an AWS DataSync agent on a new general purpose Amazon EC2 instance. Configure the DataSync agent to copy the batch of files from the NFS on-premises server to Amazon S3 Standard. After the successful copy, delete the data from the on- premises storage. Create an S3 Lifecycle rule to transition objects from S3 Standard to S3 Glacier Deep Archive after 1 day.
中文翻译：
在新的通用 Amazon EC2 实例上部署 AWS DataSync 代理。配置 DataSync 代理以将批量文件从 NFS 本地服务器复制到 Amazon S3 Standard。复制成功后，删除本地存储中的数据。创建 S3 生命周期规则以在 1 天后将对象从 S3 Standard 过渡到 S3 Glacier Deep Archive。
D. Deploy an AWS Storage Gateway Tape Gateway on premises in the Hyper-V environment. Connect the Tape Gateway to AWS. Use automatic tape creation. Specify an Amazon S3 Glacier Deep Archive pool. Eject the tape after the batch of images is copied.
中文翻译：
在 Hyper-V 环境中本地部署 AWS Storage Gateway 磁带网关。将磁带网关连接到 AWS。使用自动磁带创建。指定 Amazon S3 Glacier Deep Archive 池。复制完该批图像后弹出磁带。
答案
B
解析
正确答案：B 解析： 本题应选择 B。 正确选项： B. 将 AWS DataSync 代理部署为本地 Hyper-V 虚拟机。配置 DataSync 代理以将批量文件从 NFS 本地服务器复制到 Amazon S3 Glacier Deep Archive。复制成功后，删除本地存储中的数据。 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...
