Practice Test 3 | Google Cloud Certified Professional Data Engineer | Dumps | Mock Test
Your company is using multiple Google Cloud projects. Since maintaining and managing bills for these projects is becoming very complicated with time, management decided to unify the company’s projects into one and migrate all existing resources to a single project.
One of the projects to be migrated contains several Google Storage buckets with the total estimated file size of 25TB. This data is required to be moved to the newly created project. You need to find a secure and efficient method to migrate data. What Google Cloud product is best for this task?
A. gsutil command
B. Storage Transfer Service
C. Appliance Transfer Service
D. Dataproc
Correct Answer: B
Storage Transfer Service allows you to quickly import ONLINE data into Cloud Storage. You can also set up a repeating schedule for transferring data, as well as to transfer data within Cloud Storage, from one bucket to another.
Transfer Appliance is an OFFLINE, secure, high capacity storage server that you set up in your data center. You fill it with data and ship it to an ingest location where the data is uploaded to Google Cloud Storage.
So, option B is correct, while option C is incorrect.
Option A is incorrect: The gsutil tool is good for programmatic usage by developers and may be useful to copy and move megabytes/gigabytes of data. It’s not so practical for Terabytes of data. It’s also not a reliable data transfer technique as it is related to the machine’s connectivity with Google Cloud.
Option D is incorrect: Dataproc may help by reading from source buckets and writes into the destination buckets, but this requires data in source buckets to be used by Hadoop/Apache tools (Partitioned, optimized file formats such as ORC, ..).
