Answer: C.
Option A is INCORRECT.
AWS Global accelerator provides static IP to enable fixed entry points to your applications reducing the overhead of managing specific IP addresses.
AWS Global Accelerator helps by improving the application's availability and performance.
It does not help to upload files to S3.
Option B is INCORRECT.
Edge locations are the sites that are used by AWS CDN (Cloudfront) to serve contents to the users.
One of the characteristics of edge locations is that edge locations cache data.
Hence it helps serve the requests faster.
It is not used to help upload files to an S3 bucket.
Option C is CORRECT.
AWS S3 transfer acceleration can use optimized network protocols and the AWS edge infrastructure when uploading files to the S3 bucket.
This method is easy, secure and fast.
Option D is INCORRECT.
Snowball facilitates the transfer of huge batches of data in one go.
The typical turnaround for AWS Snowball is 5-7 days.
It is not suitable for 1TB files.

The best option to transfer files to an S3 bucket in a different region in a fast, secure, and easy way would be through AWS S3 Transfer Acceleration (Option C).
AWS S3 Transfer Acceleration is a service that enables fast, secure, and easy transfers of files over the internet to Amazon S3 buckets. It takes advantage of Amazon CloudFront's globally distributed edge locations to accelerate transfers over the public internet.
To use AWS S3 Transfer Acceleration, the customer can simply enable it on their S3 bucket in us-east-1, and then upload the files using a specially generated endpoint URL that includes the acceleration domain name. This endpoint URL can be easily shared with the customer in Tokyo.
AWS Global Accelerator (Option A) is a service that improves the availability and performance of applications by routing traffic through the AWS global network infrastructure. While it can improve performance, it is not specifically designed for file transfers and may not be the most efficient option for this use case.
AWS Edge Locations (Option B) are part of the Amazon CloudFront content delivery network and are used to cache content closer to end-users for faster access. They may be used in conjunction with AWS S3 Transfer Acceleration to further optimize performance, but alone, they are not the optimal solution for transferring large files across regions.
AWS Snowball family (Option D) is a physical data transport solution that allows for the secure and efficient transfer of large amounts of data into and out of AWS. It involves physically shipping a device (Snowball or Snowball Edge) to the customer to load the data onto, which is then shipped back to AWS to be uploaded. While this is a secure and efficient option for large data sets, it may not be the most cost-effective or practical solution for a single transfer of 1TB.
