To preserve an archive of past campaign data for later analysis, which practice is recommended?

• A. Reusing the same report indefinitely
• B. Exporting data by campaign and preserving copies in CSV or PDF
• C. Relying solely on real-time dashboards
• D. Exporting data by campaign to preserve an archive for analysis and comparison

Answer: (D)

Creating a durable historical record of campaign performance by exporting data by campaign and preserving those copies lets you analyze trends, compare outcomes across campaigns, and revisit decisions long after the live reports have updated. This archival approach gives you a time-stamped, campaign-level dataset you can reference for longitudinal analysis, benchmarking, and audits, and it remains accessible even if dashboards or source systems change. Keeping archived files in stable formats like CSV or PDF helps ensure the data stays usable over time.

Reusing the same report indefinitely doesn’t capture new information or provide a true historical view. Relying solely on real-time dashboards focuses on current status and typically lacks a retrievable record for future analysis. Exporting data by campaign without an archival intent may produce snapshots, but the explicit practice of preserving an archive is what enables ongoing analysis and meaningful cross-period comparisons.
