A customer in Tokyo requires to transfer files (total of 1TB) to his S3 bucket in us-east-1. Which of the below AWS offerings can facilitate this in an easy, secured and fast way?

Answer options:

A.AWS Global accelerator
B.AWS Edge Locations
C.AWS S3 transfer acceleration
D.AWS Snowball family

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.
