This is a shortened, original Core-style practice mock with a 45-minute clock. It mixes single-choice decisions, paired-statement and matching-style choices, and hands-on workflow tasks. The questions cover preparation, input/output, joins, reshaping, parsing and result inspection. They use the skills built in this course and are not copied from a vendor exam.
The practice label describes the requested Core-style format. It is not an official assessment, a complete current certification syllabus or a promise of certification eligibility. Read the task carefully and inspect the supplied records when a workflow is required. Several choices differ only at a boundary or an output anchor. Work steadily and use your remaining time to inspect fields, counts and exceptions rather than trusting a completed run alone.
