CompTIA Data+ DA0-001 (V1) Practice Question

Which dimension-table strategy is best for preserving older changes and new details, allowing data analysis across different time intervals?

  • Add a series of extra columns in the same record for each change

  • Create a separate temporary table for older changes and delete them on a schedule

  • Overwrite the existing record in the dimension whenever an update occurs

  • Retain older dimension details by generating a new row for each update
