Practice Test 2 | Google Cloud Certified Professional Data Engineer | Dumps | Mock Test
You have about 20TB of data which is not accessed and the data team decided to archive them in the cloud. The team is looking for a storage solution that is highly available with minimum costs. On the other hand, the data may be accessed a few times a year for reconciliation purposes. Reconciliation frequency is per month.
Which of the following choices best satisfy data team’s requirements?
A. Google Storage Standard.
B. Google Storage Nearline.
C. Google Storage Coldline.
D. BigQuery.
Correct Answer: B
Nearline Storage is a low-cost, highly durable storage service for storing infrequently accessed data. Nearline Storage is a better choice than Standard Storage in scenarios where slightly lower availability, a 30-day minimum storage duration, and costs for data access are acceptable trade-offs for lowered at-rest storage costs.
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.
————————————-
Coldline Storage is a very low-cost, highly durable storage service for storing infrequently accessed data. Coldline Storage is a better choice than Standard Storage or Nearline Storage in scenarios where slightly lower availability, a 90-day minimum storage duration, and higher costs for data access are acceptable trade-offs for lowered at-rest storage costs.
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.
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 C is incorrect: The scenario mentions the need to access the data several times a year. Hence, Coldline is not a suitable option because Coldline is to plan archive data accessed at most once a year.
Option D is incorrect: BigQuery does not have a cheaper cost for storing data than Nearline for the first 90 days until it’s moved to long-term storage.
