Question 5

What is the best way for an organization to transfer hundreds of terabytes of data from their on-premise data center into Amazon S3 with limited bandwidth available?

1. Use S3 Transfer Acceleration
2. Apply compression before uploading
3. Use AWS Snowball
4. Use Amazon CloudFront

Answer 5

3. Use AWS Snowball

Snowball is a petabyte-scale data transport solution that uses devices designed to be secure to transfer large amounts of data into and out of the AWS Cloud. Using Snowball addresses common challenges with large-scale data transfers including high network costs, long transfer times, and security concerns

• Use S3 Transfer Acceleration is incorrect. Amazon S3 Transfer Acceleration enables fast, easy, and secure transfers of files over long distances between your client and an S3 bucket. Transfer Acceleration takes advantage of Amazon CloudFront’s globally distributed edge locations. However, for these volumes of data Snowball is a better choice.
• Apply compression before uploading is incorrect as for this volume of data Snowball should be used.
• Use Amazon CloudFront is incorrect as this cannot be used for uploading large quantities of data to Amazon S3.
