Exam Professional Data Engineer topic 1 question 98 discussion

Should be A

should be A, dataflow is on cloud is external; "don't allow access from external IPs to their on-premises resources" so no dataflow.

The gcloud storage command is the standard tool for small- to medium-sized transfers over a typical enterprise-scale network, from a private data center or from another cloud provider to Google Cloud.

A is correct

A is the answer. https://cloud.google.com/architecture/migration-to-google-cloud-transferring-your-large-datasets#gsutil_for_smaller_transfers_of_on-premises_data The gsutil tool is the standard tool for small- to medium-sized transfers (less than 1 TB) over a typical enterprise-scale network, from a private data center to Google Cloud. We recommend that you include gsutil in your default path when you use Cloud Shell. It's also available by default when you install the Google Cloud CLI. It's a reliable tool that provides all the basic features you need to manage your Cloud Storage instances, including copying your data to and from the local file system and Cloud Storage. It can also move and rename objects and perform real-time incremental syncs, like rsync, to a Cloud Storage bucket.

Should be A

Without this "The security rules don't allow access from external IPs to their on-premises resources" B would be an answer.

A is the better and most simple IF there is no problem in having gsutil in our servers. B and C no way, the comms will go GCP–Home, which sais is not allowed. D is valid, we can send the files with http://ftp…BUT ftp is not secure, and we’ll need to move them to the cloud storage afterwards, which is not detailed in the answer. https://cloud.google.com/storage/docs/gsutil/commands/rsync

I am confused . which one is correct A or B ???

A is correct.

How rsynch will handle private network? "..The security rules don't allow access from external IPs to their on-premises resources.."

Vote for A

A: https://cloud.google.com/solutions/migration-to-google-cloud-transferring-your-large-datasets#options_available_from_google

gsutil rsync will be used to transfer the files ANS A

A is correct

Ans : A The gsutil rsync command makes the contents under dst_url the same as the contents under src_url, by copying any missing files/objects (or those whose data has changed), and (if the -d option is specified) deleting any extra files/objects. src_url must specify a directory, bucket, or bucket subdirectory
