UPDATE: Please be aware of the fake reviews were being posted by other courses to discredit my course, many students have reported to me that they have passed certification with more than 90% score. I actively respond to Q & A with explanations if you still have questions. These practice tests for Databricks Certified Data Engineer Associate are designed to help you understand all of the exam topics so you can pass the exam but also help you learn the concepts of the Databricks platform. It is very important to finish all 5 practice exams because each exam focuses on certain features of Databricks so you don’t want to miss out on those prior to taking the exam. My goal here is not just to help you pass the exam but help you learn the Databricks platform along the way. Here is a summary of the Databricks Certified Data Engineer Associate certification exam: The exam assesses an individuals ability to use the Databricks Lakehouse Platform to complete introductory data engineering tasks. This includes an understanding of the Lakehouse Platform and its workspace, its architecture, and its capabilities. It also assesses the ability to perform multi-hop architecture ETL tasks using Apache Spark SQL and Python in both batch and incrementally processed paradigms. Finally, the exam assesses the testers ability to put basic ETL pipelines and Databricks SQL queries and dashboards into production while maintaining entity permissions. Individuals who pass this certification exam can be expected to complete basic data engineering tasks using Databricks and its associated tools.
