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：排除明顯錯誤選項，在沒有明顯錯誤的選項中選擇最合理的選項。
某公司當前面臨的存儲挑戰(zhàn)，需要在不犧牲對最近訪問文件的低延遲訪問的同時增加可用存儲空間，并提供文件生命周期管理以避免未來的存儲問題。
A. 不正確。使用 AWS DataSync 將SMB文件服務(wù)器上超過7天的數(shù)據(jù)復(fù)制到 AWS。該解決方案只解決了數(shù)據(jù)遷移的問題，但沒有提供額外的存儲空間，也沒有實現(xiàn)文件生命周期管理。
B. 正確。創(chuàng)建 Amazon S3 File Gateway 以擴展公司的存儲空間。創(chuàng)建 S3 Lifecycle 策略以在7天后將數(shù)據(jù)遷移到 S3 Glacier Deep Archive 層。Amazon S3 File Gateway 允許將本地文件系統(tǒng)無縫擴展到云存儲，同時保持對數(shù)據(jù)的本地訪問，這對于需要低延遲訪問的數(shù)據(jù)非常有用。通過設(shè)置S3 Lifecycle 策略，可以自動將不常訪問的數(shù)據(jù)遷移到成本更低的存儲類（如 S3 Glacier Deep Archive），從而實現(xiàn)文件生命周期管理。
這個選項既解決了存儲空間的問題，又提供了文件生命周期管理，符合公司的要求。
C. 不正確。創(chuàng)建Amazon FSx for Windows File Server文件系統(tǒng)以擴展公司的存儲空間。Amazon FSx for Windows File Server 提供了完全托管的Windows文件服務(wù)器，但它主要是作為本地替代方案，而不是作為擴展存儲空間或?qū)崿F(xiàn)文件生命周期管理的工具。它沒有與S3集成來自動遷移數(shù)據(jù)。
D. 不正確。在用戶計算機上安裝實用程序以訪問Amazon S3。創(chuàng)建S3 Lifecycle策略以在7天后將數(shù)據(jù)遷移到S3 Glacier Flexible Retrieval 層。該方案需要用戶安裝額外的軟件來訪問S3，這會影響用戶體驗，并且不是無縫擴展存儲空間的解決方案。此外，雖然設(shè)置了S3 Lifecycle策略，但缺乏本地文件系統(tǒng)的低延遲訪問。
