Active standard guide · verified 15 October 2026. Official guide.

Unofficial English practice: 30 original scenarios across five domains. The real standard exam has 40–50 multiple-choice and multiple-select questions in two hours. These untimed single-choice rounds cover selected concepts and do not predict passing. For renewal requirements, use the official certification page.

Blueprint mix uses approximate guide weights 22/25/20/15/18%, rounded to whole questions. Focused rounds sample uniformly within one domain.

Keep the seed to replay the same questions and option order.
