Practice Test 2 | Google Cloud Certified Professional Data Engineer | Dumps | Mock Test
An e-payment service generates thousands of gigabytes of logs every month which are streamed to a Dataflow pipeline, transformed, and stored in a data warehouse for further analysis.
These raw logs are not accessed once the transformation is done by Dataflow. CTO suggested that log files should be archived after a month of the transformation and after making sure that the data is not required for debugging. Which of the following storage types are recommended?
A. Google Storage Standard
B. Google Storage Nearline
C. Google Storage Coldline
D. Google Storage Archive
The correct answer is Option D.
Archive storage is the lowest-cost, highly durable storage service for data archiving, online backup, and disaster recovery. Unlike the “coldest” storage services offered by other Cloud providers, your data is available within milliseconds, not hours or days.
Like Nearline storage and Coldline storage, Archive storage has a slightly lower availability than Standard storage. Archive storage also has higher costs for data access and operations, as well as a 365-day minimum storage duration. Archive storage is the best choice for data that you plan to access less than once a year.
Option A is incorrect: Google Storage Standard is not a cheap option for storing archive data. There are other options to store archive data cheaper.
Option B is incorrect: The scenario states the raw logs are to be archived after processed and kept for a month to ensure data is not required anymore. Data archived will most probably won’t be
accessed so Nearline storage is not necessary.
Answer C is incorrect: Google Storage Coldline is not apt for archival storage.
