A company is running an SMB file server in its data center. The file server stores large files that are accessed frequently for the first few days after the files are created. After 7 days the files are rarely accessed.
The total data size is increasing and is close to the company's total storage capacity. A solutions architect must increase the company's available storage space without losing low-latency access to the most recently accessed files. The solutions architect must also provide file lifecycle management to avoid future storage issues.
Which solution will meet these requirements?
A. Use AWS DataSync to copy data that is older than 7 days from the SMB file server to AWS.
B. Create an Amazon S3 File Gateway to extend the company's storage space. Create an S3 Lifecycle policy to transition the data to S3 Glacier Deep Archive after 7 days.
C. Create an Amazon FSx for Windows File Server file system to extend the company's storage space.
D. Install a utility on each user's computer to access Amazon S3. Create an S3 Lifecycle policy to transition the data to S3 Glacier Flexible Retrieval after 7 days.
B
技巧:排除明显错误选项,在没有明显错误的选项中选择最合理的选项。
某公司当前面临的存储挑战,需要在不牺牲对最近访问文件的低延迟访问的同时增加可用存储空间,并提供文件生命周期管理以避免未来的存储问题。
A. 不正确。使用 AWS DataSync 将SMB文件服务器上超过7天的数据复制到 AWS。该解决方案只解决了数据迁移的问题,但没有提供额外的存储空间,也没有实现文件生命周期管理。
B. 正确。创建 Amazon S3 File Gateway 以扩展公司的存储空间。创建 S3 Lifecycle 策略以在7天后将数据迁移到 S3 Glacier Deep Archive 层。Amazon S3 File Gateway 允许将本地文件系统无缝扩展到云存储,同时保持对数据的本地访问,这对于需要低延迟访问的数据非常有用。通过设置S3 Lifecycle 策略,可以自动将不常访问的数据迁移到成本更低的存储类(如 S3 Glacier Deep Archive),从而实现文件生命周期管理。
这个选项既解决了存储空间的问题,又提供了文件生命周期管理,符合公司的要求。
C. 不正确。创建Amazon FSx for Windows File Server文件系统以扩展公司的存储空间。Amazon FSx for Windows File Server 提供了完全托管的Windows文件服务器,但它主要是作为本地替代方案,而不是作为扩展存储空间或实现文件生命周期管理的工具。它没有与S3集成来自动迁移数据。
D. 不正确。在用户计算机上安装实用程序以访问Amazon S3。创建S3 Lifecycle策略以在7天后将数据迁移到S3 Glacier Flexible Retrieval 层。该方案需要用户安装额外的软件来访问S3,这会影响用户体验,并且不是无缝扩展存储空间的解决方案。此外,虽然设置了S3 Lifecycle策略,但缺乏本地文件系统的低延迟访问。
