Your company is moving 75 TB of data into Google Cloud. You want to use Cloud Storage and follow Google-recommended practices. What should you do?
To move 75 TB of data into Google Cloud, the recommended practice is to use the Transfer Appliance. The Transfer Appliance is designed for transferring large amounts of data securely and efficiently. Once the data is on the Transfer Appliance, the Transfer Appliance Rehydrator is used to decrypt and upload the data into Cloud Storage. This method is ideal for datasets exceeding 10 TB as it avoids the high duration and potential connectivity issues that could occur with online transfers.
It should be 'A' Transfer Appliance lets you quickly and securely transfer large amounts of data to Google Cloud Platform via a high capacity storage server that you lease from Google and ship to our datacenter. Transfer Appliance is recommended for data that exceeds 20 TB or would take more than a week to upload.
where did u get that 20 TB number - can help to share link?
Here is the link: https://cloud.google.com/transfer-appliance/docs/2.2/overview
But that link mentions a few hundred terabytes to 1 petabyte not 20TB or did I read that incorrectly?
The request transfer appliance UI seems to suggest that it is not cost effective under 20TB of data.
To this date Transfer Appliance supported locations are only United States Canada European Union Norway Switzerland. What if data reside in a location other than this? C is the most convenience for this scenario.
Why assume a scenario no provided in the question. We need to choose the best case scenario based on available information instead of making assumptions. So A should be good.
There is NO mention of region - you dont assume anything NOT mentioned in the question therefore - Ans =A
stupid answer
Why not A?
A is ok
It is A
A, anything over 10TB goes via appliance.
I have moved 120 TB using gsutil- cost effectively!
takes longer though
Answer is A.

Is Transfer Appliance suitable for me? "Your data size is greater than or equal to 10TB." https://cloud.google.com/transfer-appliance/docs/4.0/overview#suitability
A is correct ... https://cloud.google.com/architecture/migration-to-google-cloud-transferring-your-large-datasets#transfer-options 1. gsutil is for lessthan <1 TB data with enough bandwidth, so C and D can be eliminated 2. option b can be eliminated since dataprep for decription is not correct 3. so only left over is a and its offline transfer, since the question did not give any time line when the transfer to be completed
The correct answer is A: Move your data onto a Transfer Appliance. Use a Transfer Appliance Rehydrator to decrypt the data into Cloud Storage. To move large amounts of data into Google Cloud, it is recommended to use Transfer Appliance. Transfer Appliance is a physical storage device that you can use to transfer large amounts of data to Google Cloud quickly and securely. Once you have moved your data onto a Transfer Appliance, you can use a Transfer Appliance Rehydrator to decrypt the data and load it into Cloud Storage.
Option B: Using Cloud Dataprep to decrypt the data into Cloud Storage is not a valid option, as Cloud Dataprep is a data preparation tool that does not support data transfer or decryption. Option C: Using resumable transfers to upload the data into Cloud Storage is not a recommended option for moving large amounts of data, as resumable transfers are designed for smaller data sets and may not be efficient for transferring large amounts of data. Option D: Using streaming transfers to upload the data into Cloud Storage is not a recommended option for moving large amounts of data, as streaming transfers are designed for transferring real-time data streams and may not be efficient for transferring large amounts of data. Therefore, the correct answer is A: Move your data onto a Transfer Appliance. Use a Transfer Appliance Rehydrator to decrypt the data into Cloud Storage.
It will be more precise with info about the bandwidth Google says: The two main criteria to consider with Transfer Appliance are cost and speed. With reasonable network connectivity (for example, 1 Gbps), transferring 100 TB of data online takes over 10 days to complete. If this rate is acceptable, an online transfer is likely a good solution for your needs. If you only have a 100 Mbps connection (or worse from a remote location), the same transfer takes over 100 days. At this point, it's worth considering an offline-transfer option such as Transfer Appliance. So even for such 100 TB google choose between transfer appliance or online transfer. not going with gsutil at all. it is clear gsutil is suitable for small to medium size (less than 1 TB) so with no more details, google recommendation is A
gsutil is recommanded for data size less than a TB. That rules out C and D B says decrypt data using Dataprep not sure this is possible. https://cloud.google.com/solutions/migration-to-google-cloud-transferring-your-large-datasets#transfer-options
A, is the correct option for transferring data of few TB to PB. gsutil is viable option if the data size is about 1TB or less than that. Reference: https://cloud.google.com/architecture/migration-to-google-cloud-transferring-your-large-datasets
Opion A is partially correct as you would not use a Transfer Appliance Rehydrator to decrypt the data. The Transfer Appliance itself is used to encrypt and decrypt the data. Option C is correct.
I would eliminate B & C as the question clearly methos google recomendations.About 10 TB or canal to we need to me transfer appliance. Let's not worry about what regions Ohk for now. Between A & B B is over kill as transfer applion allows decryption. Hence A
https://cloud.google.com/transfer-appliance/docs/4.0/overview#suitability
A. Move your data onto a Transfer Appliance. Use a Transfer Appliance Rehydrator to decrypt the data into Cloud Storage.
Option A Use a Transfer Appliance Rehydrator
ok for A
Sending 75 TB of data on reliable 1.5 Gbps line will take about 6 days to complete data transfer online at the same time it will consume entire bandwidth. Hence use of Transfer appliace is required.
A - Correct
