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。
某公司使用NFS（网络文件系统）在本地网络附加存储中存储大型视频文件，文件大小从1 MB到500 GB不等，总存储量为70 TB且不再增长。公司决定将这些视频文件迁移到 Amazon S3，并要求尽快完成迁移，同时使用尽可能少的网络带宽。
A. 不正确。使用AWS CLI复制文件到S3 存储桶。该方案方法虽然简单直接，但考虑到文件总量为70 TB，且每个文件大小不等，通过网络直接传输可能会非常耗时，并且占用大量网络带宽。
B. 正确。使用AWS Snowball Edge。AWS Snowball Edge 是一种用于大数据迁移的物理存储设备。公司可以申请有偿使用一个 Snowball Edge设备，AWS会将其运送到公司所在地。工程师将数据传输到 Snowball Edge设备上，然后将设备返回给AWS；AWS 会将数据导入到 S3 中。这种方法非常适合大量数据的迁移，并且可以减少对网络带宽的依赖。
C. 不正确。部署 S3 File Gateway 并使用NFS文件共享。S3 File Gateway 允许在本地以文件系统的形式访问 S3 存储桶中的数据。然而，这种方法仍然需要通过网络将数据传输到 S3 File Gateway，然后再同步到 S3 存储桶，这可能会占用大量网络带宽，并且不是最高效的迁移大量数据的方法。
D. 不正确。设置 AWS Direct Connect 并使用 S3 File Gateway。AWS Direct Connect 提供了一种专用的网络连接，用于将本地网络与AWS云直接相连，但是最终数据仍需通过网络同步到S3存储桶。此外，设置AWS Direct Connect的成本和复杂性也较高。
