AWS Certified Solutions Architect Professional SAP-C02 Practice Question
A media company stores 500 TB of video files on an on-premises NFS server. The business has given the cloud team 2 weeks to migrate the data into an Amazon S3 bucket so that a new analytics pipeline can launch on schedule. The files will continue to be edited during the migration, and all changes must be captured before the final cut-over. The data center has a shared 1 Gbps internet link that cannot be saturated for an extended period, and the team wants to minimize operational effort without buying new hardware.
Which migration approach will meet the timeline and capture ongoing changes?
Deploy an AWS DataSync agent on-premises and copy all 500 TB over the 1 Gbps link, throttling bandwidth and running a final sync just before cutover.
Enable Amazon S3 Transfer Acceleration on the destination bucket and perform parallel multipart uploads of all files during off-peak hours.
Use multiple AWS Snowball Edge Storage Optimized devices for the initial 500 TB load, then run AWS DataSync to replicate incremental file changes over the existing link until cutover is complete.
Provision an SFTP server with AWS Transfer Family and script uploads from the NFS share to S3, then apply S3 Lifecycle policies for storage management.
At 1 Gbps, transferring 500 TB online would take roughly 45-50 days-far longer than the 2-week window. AWS Snowball Edge Storage Optimized devices move bulk data offline, avoiding internet bandwidth constraints; several devices (each up to 210 TB) can be filled and shipped in parallel within days. After AWS imports the devices into the target S3 bucket, installing an AWS DataSync agent on-premises allows incremental, bandwidth-throttled synchronization of only the changed files, ensuring that edits made during shipping are copied before cutover. Using DataSync alone, S3 Transfer Acceleration, or AWS Transfer Family still relies on the 1 Gbps link for the full 500 TB and therefore cannot meet the schedule, while also requiring more operational scripting and monitoring. Snowball Edge plus DataSync is the only option that satisfies the deadline, captures deltas, and keeps operational overhead low.
