Answer: Use the Storage Transfer Service after establishing a Cloud Interconnect connection between the on-premises data center and Google Cloud
To efficiently transfer a large volume of data (1 PB) within a short timeframe, employing a dedicated network connection such as Cloud Interconnect is advised. This method offers superior bandwidth and reduced latency over public internet connections. The Storage Transfer Service facilitates the movement of data between on-premises and cloud storage, compatible with Cloud Interconnect, ensuring a swift, secure, and dependable data transfer. Opting for a Transfer Appliance (Option D) involves manual data handling and may prolong the process. Similarly, utilizing gcloud compute scp jobs (Option C) might not be as efficient or reliable. Breaking down the data into smaller batches (Option A) complicates the migration and may not satisfy the urgency of the transfer requirement.
