Practice Test 1 | Google Cloud Certified Professional Data Engineer | Dumps | Mock Test
A multinational company has multiple Google Storage buckets in different regions around the world. Each branch has its own set of buckets in the region nearest to them to avoid latencies.
However, this led to a problem for the analytics team to reach and do the necessary reports on the data using BigQuery since they need to create the tables in the same region either to import the data or create external tables to access the data in different regions. The head of data decided to sync the data daily from different Google Storage buckets scattered in different regions to a single multi-regional bucket to do the necessary data analysis and reporting.
Which service could help with this approach?
A. Appliance Transfer Service
B. gsutil
C. Storage Transfer Service
D. Dataflow
Answer: C.
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 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 datacenter. You fill it with data and ship it to an ingest location where the data is uploaded to Google Cloud Storage.
So, answer C is correct, while answer A is incorrect.
Answer B is incorrect: gsutil tool is good for programmatic usage by developers and may be useful to copy and move megabytes/gigabytes of data. Not so practical for Terabytes of data. It’s also not reliable data transfer technique as it is related to the machine’s connectivity with Google Cloud.
Answer D is incorrect: Dataflow as a solution may be viable, but you need to build a pipeline to migrate data from bucket to another. Storage Transfer Service can do it without the extra effort.
