Google PCA Practice Question: Analysing and Optimising Technical and Business Processes
A company needs to transfer 200 TB of data from on-premises to Cloud Storage within one week. The on-premises network upload speed is 100 Mbps. Which method should they use?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Order a Transfer Appliance
200 TB at 100 Mbps = 200 * 1024 * 8 / (100/8) seconds ≈ 1,620,000 seconds ≈ 19 days, which exceeds one week. So network transfer is too slow. Transfer Appliance is a physical device for fast offline transfer. Storage Transfer Service is for cloud-to-cloud. gsutil rsync is an online tool. Velostrata is for VM migration.

Order a Transfer Appliance
