Transforming and Cleansing Data

Introduction

This lesson continues the domain Prepare data (45–50% of the DP-600 skills measured). This course targets the English syllabus effective October 19, 2026. Microsoft does not publish the question count or the question-type mix for the exam, so OnLevelUp mock exams use a 50-question practice length and an unofficial 80% practice target; neither is equivalent to the official 700/1000 scaled passing score.
