A. B. C. D.A.
The recommended way to move large amounts of data to Google Cloud is to use a Transfer Appliance, which is a physical device that you can use to transfer large amounts of data offline, securely, and quickly.
Option A: Move your data onto a Transfer Appliance. Use a Transfer Appliance Rehydrator to decrypt the data into Cloud Storage.
This option is partially correct. You would need to move the data onto a Transfer Appliance, but you would not use a Transfer Appliance Rehydrator to decrypt the data. The Transfer Appliance itself is used to encrypt and decrypt the data, so it would handle the decryption of the data during the transfer process. Once the data is on the Transfer Appliance, it can be securely shipped to Google's data center, where it can be uploaded to Cloud Storage.
Option B: Move your data onto a Transfer Appliance. Use Cloud Dataprep to decrypt the data into Cloud Storage.
This option is incorrect. Cloud Dataprep is a data preparation tool for cleaning and transforming data, but it is not used for decrypting data.
Option C: Install gsutil on each server that contains data. Use resumable transfers to upload the data into Cloud Storage.
This option is also correct. You can use gsutil, which is a command-line tool for managing Cloud Storage, to upload the data to Cloud Storage using resumable transfers. Resumable transfers allow you to upload large files and resume interrupted uploads. You would need to install gsutil on each server that contains data and then run the gsutil command to upload the data to Cloud Storage.
Option D: Install gsutil on each server containing data. Use streaming transfers to upload the data into Cloud Storage.
This option is incorrect. Streaming transfers are used for uploading data in real-time, such as for streaming media. They are not recommended for large-scale data transfers, as they do not provide the same level of reliability and resiliency as resumable transfers.
Therefore, the correct answer is Option C: Install gsutil on each server that contains data. Use resumable transfers to upload the data into Cloud Storage.
