Exam Professional Cloud Architect topic 1 question 152 discussion

D is ok . https://cloud.google.com/storage/docs/gsutil/commands/hash

Seems most of the questions are having wrong answers.. If there is no discussion , its highly difficult to get the right answers.

Use gsutil hash -c FILE_NAME to generate CRC32C hashes, you cannot forget to generate the hashes

created hash and compare after is way to go.

I am losing faith on the answers given... Option C is downright absurd.

https://cloud.google.com/storage/docs/gsutil/commands/hash Calculate hashes on local files, which can be used to compare with gsutil ls -L output. -c Calculate a CRC32c hash for the specified files.

Downloading before hashing cannot be right. The upload might be fine but if the download could corrupt

The correct answer should be D: https://cloud.google.com/storage/docs/gsutil/commands/hash

D is the correct answer

D is ok

Calculate hashes on local files, which can be used to compare with gsutil ls -L output. If a specific hash option is not provided, this command calculates all gsutil-supported hashes for the files. Note that gsutil automatically performs hash validation when uploading or downloading files, so this command is only needed if you want to write a script that separately checks the hash. If you calculate a CRC32c hash for files without a precompiled crcmod installation, hashing will be very slow. See gsutil help crcmod for details. https://cloud.google.com/storage/docs/gsutil/commands/hash

D is the right answer per this doc https://cloud.google.com/storage/docs/gsutil/commands/hash

All those who answered D.. can one of you if you're genuine tell how is this even possible - The second step in the option D? 2. Use gsutil hash -c FILE_NAME to generate CRC32C hashes of all on-premises files.

Correct Answer C A- digest comparison does not gurantee file contents are same. moreover lot of extra steps. - not correct B - custom Java code - lot of effort - not correct D - gs util cannot be used for creating hash for on prem files stored on on prem filestore/database. Not correct C - not the best option but right answer for the options available.

D is correct , there is no need to build custom java script.

D seems valid

I am eliminating tedious approaches that is downloading and doing custom coding so A B C are eliminated. D is the solution.
