Practice Test 3 | Google Cloud Certified Professional Data Engineer | Dumps | Mock Test
You have a system-generated log file required to be later uploaded to Google Storage in the data lake. Since the data is only accessed occasionally a few times a year by the development team for debugging and log analysis. You are looking for a cheaper storage option for log files than the standard class. Which of the following is suitable?
A. Cloud Storage Nearline
B. Cloud Storage Coldline
C. BigQuery
D. Filestore
Correct Answer: B
Option A is incorrect: Nearline Storage is ideal for data you plan to read or modify on average once per month or less. For example, if you want to continuously add files to Cloud Storage and plan to access those files once a month for analysis, Nearline Storage is a great choice.
Option B is Correct: Coldline Storage is ideal for data you plan to read or modify at most once a quarter. Note, however, that for data being kept entirely for backup or archiving purposes, Archive Storage is more cost-effective, as it offers the lowest storage costs.
Options C and D are incorrect: Both BigQuery and Filestore’s storage rate is two times higher than Cloud Storage Nearline.
