This timed practice set contains forty original single-answer and multiple-select questions about BigQuery architecture, storage, access, loading and SQL. It uses the scenario style of Google's Professional Data Engineer exam, but it covers only BigQuery with the lower end of the current exam's question count and its two-hour time limit. It is not an official exam or a complete certification assessment.
The clock gives you 120 minutes and survives page reloads. Your first submitted answer determines your practice score; later corrections help you learn without changing that score. Revealed answers count as assisted. Select one answer unless a question asks for two. You receive an explanation after each answer. When time expires, restart the attempt to submit again. A restart clears this exam's lesson progress and leaves other lessons alone.
