Your company is planning to upload several important files to Cloud Storage. After the upload is completed, they want to verify that the upload content is identical to what they have on- premises. You want to minimize the cost and effort of performing this check. What should you do?

A1) Use gsutil -m to upload all the files to Cloud Storage.
2) Use gsutil cp to download the uploaded files
3) Use Linux diff to compare the content of the files

B1) Use gsutil -m to upload all the files to Cloud Storage.
2) Develop a custom Java application that computes CRC32C hashes
3) Use gsutil ls -L gs://[YOUR_BUCKET_NAME] to collect CRC32C hashes of the uploaded files
4) Compare the hashes

C1) Use Linux shasum to compute a digest of files you want to upload
2) Use gsutil -m to upload all the files to the Cloud Storage
3) Use gsutil cp to download the uploaded files
4) Use Linux shasum to compute a digest of the downloaded files 5.Compre the hashes

D1) Use gsutil -m to upload all the files to Cloud Storage.
2) Use gsutil hash -c FILE_NAME to generate CRC32C hashes of all on-premises files
3) Use gsutil ls -L gs://[YOUR_BUCKET_NAME] to collect CRC32C hashes of the uploaded files
4) Compare the hashes

Option B is the clear winner here. Who has time to download all those files and run a diff? Not me, I'm too busy hunting Pokémon!

Plus, using gsutil ls -L gs://[YOUR_BUCKET_NAME] to collect CRC32C hashes of the uploaded files makes the comparison process much easier.

Agreed! Developing a custom Java application to compute CRC32C hashes is the most efficient way to verify the content.

I prefer option D. Generating CRC32C hashes of on-premises files before uploading and comparing them with the uploaded files seems like a thorough method to verify the content.
