An architect is reviewing several proposed migration tasks and must decide which ones genuinely warrant the AWS Snow Family rather than an online network transfer service such as DataSync or S3 Transfer Acceleration. The estate spans sites with very different connectivity and data profiles, and the cost and timeline must be defensible to the programme board. The architect wants to apply the offline Snow Family approach only where the data volume and connectivity actually justify it. For which THREE of the following situations is the AWS Snow Family the MOST appropriate choice? Select THREE.
- AA site must move 500 TB to Amazon S3 within three weeks, but its only link is a shared 50 Mbps internet connection that a network-only copy would take many months to complete and would saturate. Correct
- BA remote sensor station with no reliable internet connectivity must move 80 TB of collected data to AWS, and the only feasible path is to capture the data locally and ship a device. Correct
- CA one-time migration of 200 TB must complete before a lease ends in a month, and the available bandwidth would need far longer than that to transfer the full dataset over the network. Correct
- DA site must replicate 5 TB of changed files into S3 every night over an existing, lightly used 10 Gbps Direct Connect link, verifying integrity and copying only the delta on each run.
- EExternal partners must upload modest daily files into S3 using their own SFTP clients and credentials on an ongoing basis without the company running a file server.
Why A is correct: The data volume vastly exceeds what a 50 Mbps link can carry inside the deadline, which is exactly the condition where an offline Snow Family shipment beats any online transfer service.
Why B is correct: With no usable connectivity at the edge site, an online transfer service cannot run, so capturing the data onto a Snow Family device and shipping it is the appropriate mechanism.
Why C is correct: When the bandwidth cannot move the full volume inside a hard deadline, the offline shipment time of a Snow Family device becomes the faster and lower-risk path, so it is the right call.
Why D is wrong: A small recurring delta over an existing high-bandwidth link is a textbook DataSync scheduled task, so shipping a device nightly would be slower and far higher overhead than an online transfer.
Why E is wrong: Recurring small partner uploads over SFTP are served by AWS Transfer Family, not an offline device, so the Snow Family does not fit this protocol-based ingestion pattern at all.
