CompTIA Cloud+ (CV0-004)Cloud ArchitectureMedium
A cloud architect is designing a solution for storing infrequently accessed archive data that needs to be retained for several years due to regulatory compliance. Retrieval times can be several hours, but cost optimization is a primary concern. Which storage tier is most appropriate?
- ACold Object Storage (Archive)
- BFile Storage (NFS)
- CHot Object Storage
- DStandard Block Storage
Show answer & explanationAnswer & explanation
Correct answer: A. Cold Object Storage (Archive)
Cold Object Storage (Archive tier) is specifically designed for very infrequently accessed data, offering the lowest storage costs. It accepts retrieval times of several hours, which matches the scenario's requirements for long-term retention and cost optimization.
Why the other options are wrong
- B. File Storage (NFS) is for shared file access, not typically optimized for extremely low-cost, long-term archival storage.
- C. Hot Object Storage is for frequently accessed, unstructured data, also too expensive for infrequent archives.
- D. Standard Block Storage is for active, frequently accessed data with low latency, making it too expensive for archives.
Cold Object Storage (Archive)
A storage tier designed for long-term retention of data that is accessed very infrequently, characterized by the lowest storage costs and potentially longer retrieval times.
- Optimized for cost savings on archival data.
- Suitable for regulatory compliance and disaster recovery backups.
- Retrieval times can range from minutes to hours.
Memory trick: For 'archive' data that's 'cold' and 'cheap', choose 'Cold Object Storage'.
