I passed the exam last week and I strongly advise to complement the Advanced Data Engineering courses with the Apache Spark Developer Learning path. It's also very useful to not just take the courses but also look through Spark/Databricks documentation the courses link to. A lot of the questions require a deep understanding of what happens in back-end in terms of optimizations etc. Taking the courses alone and going through the labs won't get you far in my opinion...Timing is also limited with 2hours for 60questions, so you won't have a ton of time to think about every question.
