Question #978
A company is conducting a week-long experiment in a remote area with no internet connectivity. Sensors on a local network will generate 8 TB of data in a proprietary format. The sensors can upload data via FTP but lack an FTP server. The company needs to aggregate the data centrally and transfer it to Amazon S3 immediately after the experiment.
Which solution meets these requirements?
Order an AWS Snowball Edge Storage Optimized device. Connect it to the local network. Configure AWS DataSync to transfer data to the device via NFS. After the experiment, return the device to AWS to load the data into Amazon S3.
Order an AWS Snowcone device with an Amazon Linux 2 AMI. Connect it to the local network. Launch an Amazon EC2 instance on the device and create a script to pull data from the sensors. Return the device to AWS to load the data into an Amazon EBS volume.
Order an AWS Snowball Edge Compute Optimized device. Connect it to the local network. Launch an Amazon EC2 instance on the device, install an FTP server, and configure the sensors to upload data to the instance. Return the device to AWS to load the data into Amazon S3.
Order an AWS Snowcone device. Configure it with Amazon FSx. Configure the sensors to upload data to the FSx file system. Use AWS DataSync to synchronize the data with an Amazon S3 bucket. Return the device to AWS.
Explanation
Option C is correct because:
- Snowball Edge Compute Optimized supports EC2 instances, allowing the installation of an FTP server to accept sensor uploads.
- Sensors can upload data via FTP to the EC2 instance, aggregating 8TB locally.
- After the experiment, returning the device to AWS loads data directly into S3.
Other options fail because:
- A: Uses NFS via DataSync, but sensors require FTP, which isn't addressed.
- B: Snowcone lacks sufficient storage (8TB) and EC2 on Snowcone cannot pull data without an FTP server.
- D: FSx and DataSync require internet connectivity for synchronization, which isn't available during the experiment.
Key Points: Use Snowball Edge Compute Optimized for EC2 instances to host services (e.g., FTP) in disconnected environments. Data is imported to S3 when the device is returned.
Answer
The correct answer is: C
