What 1Z0‑071 emphasizes (in one paragraph)

Expect scenario questions about correct SELECT construction, filtering and NULL behavior, join semantics, grouping and aggregation, subqueries, set operators, and DDL/DML basics. Many wrong answers are “almost right” but fail on edge cases (NULL, LEFT JOIN filtering, duplicates, or grouping granularity).
