What is a primary benefit of data retention rollups in NPM?

• A. They reduce storage needs while preserving trend data.
• B. They eliminate the need for backups.
• C. They increase data retention requirements.
• D. They render real-time dashboards unusable.

Answer: (D)

Data retention rollups are about keeping long-term visibility while using less storage. By aggregating many raw data points into coarser time intervals (for example, converting several minutes of data into an hourly rollup), you dramatically reduce the number of samples that need to be stored. This lowers storage requirements without sacrificing the ability to see how metrics trend over extended periods, which is essential for capacity planning and long-term performance analysis. These rollups don’t replace backups, and they don’t force you to keep more data; they make it feasible to retain historical trends with far less storage. They also don’t render dashboards unusable—near‑term dashboards can still display granular, real-time data, while older data is available in rolled‑up form to support long-term insights.
