A company uses NFS to store large video files in on-premises network attached storage. Each video file ranges in size from 1 MB to 500 GB. The total storage is 70 TB and is no longer growing. The company decides to migrate the video files to Amazon S3. The company must migrate the video files as soon as possible while using the least possible network bandwidth.
Which solution will meet these requirements?
A. Create an S3 bucket. Create an IAM role that has permissions to write to the S3 bucket. Use the AWS CLI to copy all files locally to the S3 bucket.
B. Create an AWS Snowball Edge job. Receive a Snowball Edge device on premises. Use the Snowball Edge client to transfer data to the device. Return the device so that AWS can import the data into Amazon S3.
C. Deploy an S3 File Gateway on premises. Create a public service endpoint to connect to the S3 File Gateway. Create an S3 bucket. Create a new NFS file share on the S3 File Gateway. Point the new file share to the S3 bucket. Transfer the data from the existing NFS file share to the S3 File Gateway.
D. Set up an AWS Direct Connect connection between the on-premises network and AWS. Deploy an S3 File Gateway on premises. Create a public virtual interface (VIF) to connect to the S3 File Gateway. Create an S3 bucket. Create a new NFS file share on the S3 File Gateway. Point the new file share to the S3 bucket. Transfer the data from the existing NFS file share to the S3 File Gateway.

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。
某公司使用NFS（網絡文件系統）在本地網絡附加存儲中存儲大型視頻文件，文件大小從1 MB到500 GB不等，總存儲量為70 TB且不再增長。公司決定將這些視頻文件遷移到 Amazon S3，并要求盡快完成遷移，同時使用盡可能少的網絡帶寬。
A. 不正確。使用AWS CLI復制文件到S3 存儲桶。該方案方法雖然簡單直接，但考慮到文件總量為70 TB，且每個文件大小不等，通過網絡直接傳輸可能會非常耗時，并且占用大量網絡帶寬。
B. 正確。使用AWS Snowball Edge。AWS Snowball Edge 是一種用于大數據遷移的物理存儲設備。公司可以申請有償使用一個 Snowball Edge設備，AWS會將其運送到公司所在地。工程師將數據傳輸到 Snowball Edge設備上，然后將設備返回給AWS；AWS 會將數據導入到 S3 中。這種方法非常適合大量數據的遷移，并且可以減少對網絡帶寬的依賴。
C. 不正確。部署 S3 File Gateway 并使用NFS文件共享。S3 File Gateway 允許在本地以文件系統的形式訪問 S3 存儲桶中的數據。然而，這種方法仍然需要通過網絡將數據傳輸到 S3 File Gateway，然后再同步到 S3 存儲桶，這可能會占用大量網絡帶寬，并且不是最高效的遷移大量數據的方法。
D. 不正確。設置 AWS Direct Connect 并使用 S3 File Gateway。AWS Direct Connect 提供了一種專用的網絡連接，用于將本地網絡與AWS云直接相連，但是最終數據仍需通過網絡同步到S3存儲桶。此外，設置AWS Direct Connect的成本和復雜性也較高。
