Hi @shilpashivamall ,

At the moment, the best source to prepare for this exam is Databricks Academy. Why do I think so? Because starting from September 30th, a new version of the exam will be introduced, and most of the Udemy courses have not yet been updated.

I recommend going through the Data Engineering Path on Databricks Academy. You can also wait for the update of the course below. The author has promised to update content of the course to align with new exam objectives:

Databricks Certified Data Engineer Professional -Preparation | Udemy

He also provides practice questions which were really useful in my preparations. I guess those also be updated soon.
