GCP Professional Cloud Architect Practice Question
Your media company must migrate 400 TB of archived video from an on-prem NFS server to a new Cloud Storage Archive bucket within four weeks. The only Google Cloud path is a shared 200 Mbps WAN link, so continuous bulk transfer is unacceptable. After the seed load, about 2 TB of new footage will arrive each week and must sync to the bucket over the WAN with minimal effort. Which data-movement approach best meets these schedule and operational needs?
Use Transfer Appliance for the initial 400 TB ingest, then configure recurring Storage Transfer Service jobs from the on-prem agent to push weekly deltas.
Provision a 10 Gbps Partner Interconnect and use Storage Transfer Service for the full load and weekly updates.
Mount the Archive bucket with Cloud Storage FUSE, copy the bulk data locally, and order a new Transfer Appliance each week for incremental loads.
Copy all data with gsutil -m over the 200 Mbps link and use a weekly rsync script for the deltas.
A Transfer Appliance can ingest hundreds of terabytes by physically shipping an encrypted device, completing the initial 400 TB load within the four-week window without stressing the 200 Mbps link. Once the seed data is uploaded, Storage Transfer Service can run scheduled, incremental transfers from an on-premises agent, moving the 2 TB weekly deltas over the existing WAN with throttling and retries. Copying 400 TB over a 200 Mbps circuit would take roughly six months, repeated Transfer Appliance orders add unnecessary overhead, and deploying a 10 Gbps Partner Interconnect would be costly and time-consuming for this short-term need.
