- A
Archive storage class
Archive is the lowest-cost option for data accessed less than once a year.
- B
Coldline storage class
Why wrong: Coldline is for data accessed less than once a quarter, but Archive is cheaper.
- C
Standard storage class
Why wrong: Standard is for frequently accessed data and costs more.
- D
Nearline storage class
Why wrong: Nearline is designed for data accessed less than once a month, but still more expensive than Archive.

This GCDL practice question tests your understanding of gcdl exam topics. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A retail company stores petabytes of customer transaction data for compliance reasons. They access data less than once a year but must retain it for 10 years. They want the lowest-cost storage. Which storage class should they choose?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Archive storage class
Archive storage class is the correct choice because it is designed for data accessed less than once a year, with the lowest storage cost among Google Cloud storage classes. The customer's requirement of retaining data for 10 years with infrequent access aligns perfectly with Archive's 365-day minimum storage duration and retrieval costs that are higher but acceptable given the rare access pattern.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Google Cloud often tests the misconception that 'Coldline' is the lowest-cost option because of its name, but Archive is actually cheaper for data accessed less than once a year, and candidates overlook the access frequency and minimum storage duration requirements.
Detailed technical explanation
How to think about this question
Archive storage class uses erasure coding and is stored on lower-cost, higher-latency media, with retrieval times typically ranging from minutes to hours (e.g., 1-15 minutes for expedited access). The minimum storage duration of 365 days means deleting data earlier incurs a pro-rated charge, which is a key cost consideration for 10-year retention. In real-world scenarios, compliance data like financial records often uses Archive to balance regulatory requirements with budget constraints, and retrieval is typically automated via batch jobs or legal hold requests.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.

| 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 |
