CompTIA Data+ DA0-002 (V2) Practice Question

While building a performance dashboard, a data analyst needs to identify product categories whose combined unit sales meet or exceed 1,000 units so that only high-volume categories appear in a chart. The transactional table sales.detail stores one row per product sold and includes the columns product_id, category_id, and units_sold.

Which SQL statement will return only the qualifying categories and their total units sold without generating a syntax error?

  • SELECT category_id,
       SUM(units_sold) AS total_units
FROM   sales.detail
WHERE  units_sold >= 1000
GROUP BY category_id;

  • SELECT category_id,
       SUM(units_sold) AS total_units
FROM   sales.detail
GROUP BY category_id
HAVING SUM(units_sold) >= 1000;

  • SELECT category_id,
       SUM(units_sold) AS total_units
FROM   sales.detail
WHERE  SUM(units_sold) >= 1000
GROUP BY category_id;

  • SELECT category_id,
       SUM(units_sold) AS total_units
FROM   sales.detail
GROUP BY category_id
HAVING COUNT(units_sold) >= 1000;
