This CV0-004 practice question tests your understanding of operations and support. 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 uses a cloud object storage service to store backup data. The cloud provider charges for storage and retrieval. The operations team wants to minimize costs while ensuring data is available within 24 hours of a restore request. Which storage tier should they use?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "minimum / minimize"
Why it matters: Asks for the least resource use — fewest addresses, smallest subnet, lowest overhead. Eliminate over-provisioned options even if they would technically work.
Archive storage tier with retrieval time of 48 hours
Why wrong: Archive retrieval exceeds 24-hour requirement.
Hot storage tier
Why wrong: Hot storage is optimized for frequent access, more expensive.
Cold storage tier with retrieval time of 12 hours
Cold storage offers low cost and retrieval within 24 hours.
Infrequent access tier with retrieval time of 1 hour
Why wrong: Infrequent access is more expensive than cold for backup data.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Cold storage tier with retrieval time of 12 hours
Option C is correct because the cold storage tier offers a retrieval time of 12 hours, which meets the requirement of making data available within 24 hours while minimizing costs compared to hotter tiers. Cold storage is designed for infrequently accessed data with longer retrieval times, providing a cost-effective balance between availability and expense for backup data that does not need immediate access.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Archive storage tier with retrieval time of 48 hours
Why it's wrong here
Archive retrieval exceeds 24-hour requirement.
Hot storage tier
Why it's wrong here
Hot storage is optimized for frequent access, more expensive.
Cold storage tier with retrieval time of 12 hours
Why this is correct
Cold storage offers low cost and retrieval within 24 hours.
Clue confirmation
The clue word "minimum / minimize" in the question point toward this answer.

Infrequent access tier with retrieval time of 1 hour
Why it's wrong here
Infrequent access is more expensive than cold for backup data.
Common exam traps
The trap here is that candidates may confuse 'cold storage' with 'archive storage' or assume that any tier with a retrieval time under 24 hours is equally cost-effective, overlooking that cold storage specifically balances cost and retrieval time for infrequent access needs.
Detailed technical explanation
Cloud object storage tiers like cold storage typically use lower-cost media (e.g., magnetic tape or slower HDDs) and may involve a retrieval process that stages data to a faster tier, incurring a delay (e.g., 12 hours) and retrieval fees. In practice, backup data often has a recovery point objective (RPO) and recovery time objective (RTO) that align with cold storage's 12-hour retrieval, making it ideal for scenarios like weekly backups where cost savings are prioritized over speed.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A practitioner preparing for the CV0-004 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
