AWS Certified Solutions Architect – Professional (SAP-C02) — Question 441

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?

Answer options

• 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.
• 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.
• 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.
• 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.

Correct answer: C

Explanation

AWS Snowcone supports launching Amazon EC2 instances locally, which allows the company to host an FTP server to receive files from the sensors that only support FTP uploads. Since the sensors cannot act as FTP servers themselves, a local FTP server must be hosted on the Snowcone device using an Amazon Linux 2 AMI. Once the experiment concludes, returning the Snowcone device to AWS allows the collected data to be imported directly into Amazon S3, fulfilling the object storage requirement.
