A company needs to store petabytes of archival data that is accessed very infrequently (less than once per year) but must be available within minutes when requested. Cost optimization is a primary concern. Which Google Cloud Storage class should be chosen?
- ANearline storage
- BStandard storage
- CArchive storage
- DColdline storage
Show answer & explanationAnswer & explanation
Correct answer: C. Archive storage
Archive storage is designed for long-term archival data that is accessed less than once a year, offering the lowest storage costs but with higher access costs and a minimum storage duration of 365 days. It meets the requirement for infrequent access and cost optimization.
Why the other options are wrong
- A. Nearline storage is for data accessed less than once a month, which is more frequent than the stated requirement.
- B. Standard storage is for frequently accessed data and would be too expensive for archival data accessed less than once per year.
- D. Coldline storage is for data accessed less than once a quarter, still more frequent than the stated requirement.
Google Cloud Storage Classes
Google Cloud Storage offers different storage classes optimized for specific access patterns and cost requirements, from frequently accessed to long-term archives.
- Standard: frequently accessed.
- Nearline: accessed less than once a month.
- Coldline: accessed less than once a quarter.
- Archive: accessed less than once a year.
Memory trick: Standard is quick, Nearline's a month, Coldline's a quarter, Archive's a year.
