CV0-004 Practice Question: A company uses a cloud object storage service to…
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?
⚠ Common exam trap
Watch out — candidates often 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.
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
✓
Cold storage tier with retrieval time of 12 hours
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.
