CompTIA Data+ DA0-001 (V1) Practice Question

While reviewing an inventory dataset, a data analyst notices that warehouse clerks type the literal string "EMPTY" in the Quantity field whenever an item is out of stock. Because the column is stored as text, any numeric aggregations fail. Which remediation preserves all rows and restores the column to a usable numeric format?

  • Move rows with "EMPTY" quantities to a separate holding table

  • Replace each "EMPTY" entry with the numeric value 0

  • Change the entire Quantity column to a text data type

  • Delete every row that contains an "EMPTY" quantity
