Cloud Digital Leader Why Cloud Technology Can Transform Business Practice Question
A company wants to reduce its cloud spending by optimizing storage costs for infrequently accessed data. Which THREE Google Cloud storage classes should they consider? (Choose three.)
⚠ Common exam trap
GCDL often tests the confusion between storage class (access frequency tier) and storage location (Regional/Multi-regional), causing candidates to select Regional as if it were a cold tier.

Correct answer & explanation
✓
Archive
The scenario asks for storage classes suited to infrequently accessed data to cut costs, and the three marked options fit that profile. C (Archive) is correct because it is the lowest-cost class for data accessed less than once a year, with a 365-day minimum storage duration, ideal for long-term retention. D (Coldline) is correct because it targets data accessed less than once a quarter, offering low cost with a 90-day minimum storage duration. E (Nearline) is correct because it is designed for data accessed less than once a month, providing lower cost than hotter classes with a 30-day minimum storage duration. A (Standard) is not appropriate because it is the highest-cost class for frequently accessed data, and B (Regional) is not a storage class but a location type that can apply to Standard, Nearline, Coldline, or Archive, so neither reduces cost for infrequent access.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Standard
Why it's wrong here
The Standard storage class is the default for frequently accessed data and carries the highest per-GB price with no retrieval fees, but it is the least cost-effective choice for archival data because the company's goal is to reduce spending on data that is rarely accessed. Unlike Archive or Coldline, Standard has no minimum retention period, but that benefit does not justify its premium cost for infrequent or cold data.
- ✗
Regional
Why it's wrong here
The Regional storage class is a redundancy option rather than a cost-saving tier; it stores data redundantly within a single region and costs significantly more per GB than Standard. It is designed for frequently accessed data that needs regional availability, not for archival or cold data, so choosing it would directly contradict the company's objective to reduce cloud spending.
- ✓
Archive
Why this is correct
The Archive storage class is the lowest-cost option in Google Cloud, specifically designed for data accessed less than once per year, making it the ideal choice for long-term archival data. It has a 365-day minimum storage duration and higher retrieval fees than other classes, but for data that is rarely accessed, the dramatic reduction in storage cost offers the greatest overall savings, which is why it is the correct answer.
- ✓
Coldline
Why this is correct
The Coldline storage class is a low-cost option for cold data that is expected to be accessed no more than once every 90 days. It offers a lower per-GB storage price than Standard and Regional, with retrieval fees higher than Nearline but lower than Archive, making it a correct cost-optimization choice for data that is accessed slightly more often than true archive data.
- ✓
Nearline
Why this is correct
The Nearline storage class is built for infrequently accessed data that is expected to be read or modified no more than once every 30 days. It provides substantial storage cost savings compared to Standard and Regional, with lower retrieval fees than Coldline and Archive, so it is a correct option for reducing expenses when data access is occasional but not truly archival.

| Storage Class | Min Duration | Retrieval | Use Case |
|---|---|---|---|
| S3 Standard | None | Immediate | Frequently accessed data |
| S3 Standard-IA | 30 days | Immediate | Infrequent access, rapid retrieval |
| S3 One Zone-IA | 30 days | Immediate | Non-critical infrequent data |
| S3 Intelligent-Tiering | None | Immediate–hours | Unknown or changing access patterns |
| S3 Glacier Instant | 90 days | Milliseconds | Archive with instant retrieval |
| S3 Glacier Flexible | 90 days | Minutes–hours | Archive, flexible retrieval |
| S3 Glacier Deep Archive | 180 days | Hours | Long-term compliance archive |
