You need to migrate 1 PB of data from an on-premises data center to Google Cloud. Data transfer time during the migration should take only a few hours. You want to follow Google-recommended practices to facilitate the large data transfer over a secure connection. What should you do?

A. Establish a Cloud Interconnect connection between the on-premises data center and Google Cloud, and then use the Storage Transfer Service. B. Use a Transfer Appliance and have engineers manually encrypt, decrypt, and verify the data. C. Establish a Cloud VPN connection, start gcloud compute scp jobs in parallel, and run checksums to verify the data. D. Reduce the data into 3 TB batches, transfer the data using gsutil, and run checksums to verify the data.
