[All Professional Cloud Architect Questions]

For this question, refer to the TerramEarth case study. TerramEarth has about 1 petabyte (PB) of vehicle testing data in a private data center. You want to move the data to Cloud Storage for your machine learning team. Currently, a 1-Gbps interconnect link is available for you. The machine learning team wants to start using the data in a month. What should you do?

  • A. Request Transfer Appliances from Google Cloud, export the data to appliances, and return the appliances to Google Cloud.
  • B. Configure the Storage Transfer service from Google Cloud to send the data from your data center to Cloud Storage.
  • C. Make sure there are no other users consuming the 1Gbps link, and use multi-thread transfer to upload the data to Cloud Storage.
  • D. Export files to an encrypted USB device, send the device to Google Cloud, and request an import of the data to Cloud Storage.

Storage Transfer Service is usually for inter cloud, if you don't see any other cloud or cloud storage compliant service as the source you can ignore that option, as it is in this question - Storage Transfer Service Transfer data quickly and securely between object and file storage across Google Cloud, Amazon, Azure, on-premises, and more.

Selected Answer: A
Answer is A. https://cloud.google.com/transfer-appliance/docs/4.0/overview#location-availability With a typical network bandwidth of 100 Mbps, one petabyte of data takes about 3 years to upload. However, with Transfer Appliance, you can receive the appliance and capture a petabyte of data in under 25 days. Your data can be accessed in Cloud Storage within another 25 days, all without consuming any outbound network bandwidth. with 1GBps - online STS will take 124 days ..
