LibertyMunson Thank you for replying.
1. Got it. Thank you.
2. I read your blog indeed. And, I have been learning and working with Azure Services for the past year as a Data Engineer. And hands-on experience for the contents in the outline.
3. I did not provide any details about the exam, not here, not anywhere. Was point 3 in my previous comment providing too much detail? If yes, I am sorry, and I would like to remove it. How can I do that? I respect the NDA. The purpose to mention SQL implementation was that for some SQL implementations, Python and Scala do the same job better in a much manageable way, in real-world projects. Focusing on Python or Scala implementations won't be enough. SQL, Python, and Scala are the three languages mentioned in the outline, BTW.
