My preparation strategy involved completing the entire DP-600 learning path on Microsoft Learn to grasp the core concepts, followed by additional targeted techniques. This comprehensive approach enabled me to pass the exam. 1) Start by taking the assessment test from the link below to identify the areas where you need improvement and target those. The questions in this test are more challenging than those in the actual exam, so aim for a score between 80% and 90%.

It's a good idea to allocate 15–20 minutes specifically for the case study section. 3) Since SQL is fundamental to working with databases, you can expect around 4–5 questions focused on key concepts such as CTEs, joins, GROUP BY, HAVING clauses, and window functions. Additionally, be prepared to use aggregation functions like MAX(), GREATEST(), MIN(), or LEAST() in various scenarios. 4) KQL is a relatively new query language that shares similarities with SQL. If you're already comfortable with SQL, you can refer to the cheat sheet below to get up to speed quickly. You can expect around 3 to 4 questions on KQL in the exam.

Type 2 SCD is especially critical, as it's the most used method for tracking historical changes. In the exam, expect at least 2–4 questions related to SCDs.
