#81 Roadmap to conquer Microsoft Certified: Data Engineer Associate certification exam (DP-203)
Since I am closely working with Azure Databricks and Data engineering in general, this exam turned out to be surprisingly easy for me. If you have been working for a while with Azure Databricks, Azure Data Factory and Synapse, this exam is tailored perfectly for you. Don’t hesitate and take the exam right away :) (I personally only went through some free questions on Exam Topics of roughly 120 questions and used my common sense from work experience to pass this exam.

Structure of DP-203 exam
- Design and implement data storage (40–45%)
- Design and develop data processing (25–30%)
- Design and implement data security (10–15%)
- Monitor and optimize data storage and data processing (10–15%)
Focuses of exam
Next, let’s discuss some of the centrics in preparation phase of this DP-203 exam.
Basic data and cloud knowledge
If you are not yet familiar with data engineering and cloud technology in general, I suggest taking first all 900 series, especially dp-900 to grab all basic concepts and terminology regarding data engineering and cloud technology before taking this exam.
To the surprise of many, data engineers spend an abundance amount of time working around with SQL. It is of importance to deeply understand SQL queries and how to manipulate data with SQL. This exam requires you to be extra careful to query data from different sources.
Below example actually returns error rather than giving any data since the the source that data is retrieved from is invalid (with extra .dbo in the middle while…
