- A
Nearline Storage
Why wrong: Nearline is for data accessed less than once a month, not as cost-effective for yearly access.
- B
Regional persistent disk
Why wrong: Persistent disk is for VM storage and not designed for long-term archival; cost is higher.
- C
Archive Storage
Archive Storage has the lowest cost for data accessed less than once a year and with a 365-day minimum.
- D
Coldline Storage
Why wrong: Coldline is for data accessed less than once a quarter; still more expensive than Archive.

Google ACE Practice Question: Store 50 TB of access logs that are rarely…
This ACE practice question tests your understanding of ace 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 company needs to store 50 TB of access logs that are rarely accessed (once a year) and must be retained for 7 years. Which storage option is the most cost-effective?

Correct answer & explanation
✓
Archive Storage
Archive Storage is the most cost-effective option for data that is accessed less than once a year and must be retained for 7 years. It offers the lowest storage cost among Google Cloud storage classes, specifically designed for long-term, infrequently accessed data with a 365-day minimum storage duration and a higher retrieval cost, which is 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 distinction between Coldline and Archive storage by making candidates assume 'cold' is the cheapest, but Archive Storage is the true lowest-cost tier for data accessed less than once a year, with a longer minimum storage duration and higher retrieval fees.
Detailed technical explanation
How to think about this question
Google Cloud Archive Storage uses a single-redundancy model (no geo-redundancy) to achieve the lowest storage cost, with a 365-day minimum storage duration and a 0.0012 USD per GB per month price (as of standard pricing). Retrieval costs are higher (e.g., 0.05 USD per GB) and data cannot be accessed directly; it must be restored to a standard storage class first, which can take up to 24 hours. This trade-off is ideal for compliance-driven retention where access is rare, such as audit logs or legal holds.
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.

AWS S3 Storage Class Comparison
| 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 |
