A company must move 80 TB of archived data from its on-premises data centre to Amazon S3, but its internet link is slow and a transfer over the network would take many weeks. Which AWS service is designed to move this bulk data into AWS without relying on that link?
- AAmazon S3 Transfer Acceleration, which speeds uploads over the public internet
- BAWS Snowball, a physical device shipped to the site to load data and return Correct
- CAWS Direct Connect, a dedicated private circuit running into an AWS Region
- DAmazon CloudFront, a content delivery network that caches files near users
Why A is wrong: Transfer Acceleration uses optimised network paths but still depends on the internet link, so it cannot rescue a transfer that the bandwidth itself makes too slow.
Why B is correct: AWS Snowball ships a rugged physical device to the customer site, so a large dataset is loaded locally and posted back, bypassing the slow internet link entirely.
Why C is wrong: Direct Connect gives a private link but takes weeks to provision and is built for ongoing traffic, not a one-off bulk move when the existing link is the problem.
Why D is wrong: CloudFront distributes content out to viewers at edge locations, so it has no role in importing a large dataset from a data centre into AWS.
