SAP-C02 第 449 题
题目
A company needs to gather data from an experiment in a remote location that does not have internet connectivity. During the experiment, sensors that are connected to a local network will generate 6 TB of data in a proprietary format over the course of 1 week. The sensors can be configured to upload their data files to an FTP server periodically, but the sensors do not have their own FTP server. The sensors also do not support other protocols. The company needs to collect the data centrally and move the data to object storage in the AWS Cloud as soon as possible after the experiment. Which solution will meet these requirements?

一家公司需要从没有互联网连接的远程位置的实验中收集数据。实验期间，连接到本地网络的传感器将在 1 周内以专有格式生成 6 TB 数据。传感器可以配置为定期将其数据文件上传到 FTP 服务器，但传感器没有自己的 FTP 服务器。传感器也不支持其他协议。公司需要在实验结束后尽快集中收集数据并将数据迁移到AWS云中的对象存储中。哪种解决方案可以满足这些要求？
选项
A. Order an AWS Snowball Edge Compute Optimized device. Connect the device to the local network. Configure AWS DataSync with a target bucket name, and unload the data over NFS to the device. After the experiment, return the device to AWS so that the data can be loaded into Amazon S3.

订购 AWS Snowball Edge 计算优化设备。将设备连接到本地网络。使用目标存储桶名称配置 AWS DataSync，并通过 NFS 将数据卸载到设备。实验结束后，将设备返回AWS，以便将数据加载到Amazon S3中。
B. Order an AWS Snowcone device, including an Amazon Linux 2 AMI. Connect the device to the local network. Launch an Amazon EC2 instance on the device. Create a shell script that periodically downloads data from each sensor. After the experiment, return the device to AWS so that the data can be loaded as an Amazon Elastic Block Store (Amazon EBS) volume.

订购 AWS Snowcone 设备，包括 Amazon Linux 2 AMI。将设备连接到本地网络。在设备上启动 Amazon EC2 实例。创建一个 shell 脚本，定期从每个传感器下载数据。实验结束后，将设备返回到 AWS，以便可以将数据作为 Amazon Elastic Block Store (Amazon EBS) 卷加载。
C. Order an AWS Snowcone device, including an Amazon Linux 2 AMI. Connect the device to the local network. Launch an Amazon EC2 instance on the device. Install and configure an FTP server on the EC2 instance. Configure the sensors to upload data to the EC2 instance. After the experiment, return the device to AWS so that the data can be loaded into Amazon S3.
中文翻译：
订购 AWS Snowcone 设备，包括 Amazon Linux 2 AMI。将设备连接到本地网络。在设备上启动 Amazon EC2 实例。在 EC2 实例上安装并配置 FTP 服务器。配置传感器以将数据上传到 EC2 实例。实验结束后，将设备返回AWS，以便将数据加载到Amazon S3中。
D. Order an AWS Snowcone device. Connect the device to the local network. Configure the device to use Amazon FSx. Configure the sensors to upload data to the device. Configure AWS DataSync on the device to synchronize the uploaded data with an Amazon S3 bucket. Return the device to AWS so that the data can be loaded as an Amazon Elastic Block Store (Amazon EBS) volume.
中文翻译：
订购 AWS Snowcone 设备。将设备连接到本地网络。配置设备以使用 Amazon FSx。配置传感器以将数据上传到设备。在设备上配置 AWS DataSync 以将上传的数据与 Amazon S3 存储桶同步。将设备返回给 AWS，以便可以将数据作为 Amazon Elastic Block Store (Amazon EBS) 卷加载。
