What is a data lifecycle policy in cloud storage?

• A. Rules that manually move data between storage tiers
• B. Rules that automatically transition data between storage tiers and delete data after a retention period
• C. Policies for controlling who can delete data
• D. Guidelines for data replication across regions

Answer: (B)

A data lifecycle policy in cloud storage is about automating how data is managed as it ages. It uses rules to move objects to appropriate storage tiers automatically—so newer or frequently accessed data stays in faster, more expensive tiers, while older or less-accessed data shifts to cheaper, long-term storage. It can also automatically delete data after a defined retention period to meet regulatory or organizational requirements. This combination of automatic tiering and automatic deletion is what makes lifecycle policies powerful for cost control and governance. Manual data movement would be labor-intensive and error-prone, which is why it isn’t the best description. Policies about who can delete data relate to access control, not lifecycle management. Guidelines for data replication across regions deal with redundancy and disaster recovery, not lifecycle aging and retention.
