In Data modeling section, the correct answer is Type 2: Adding a new row with a timestamp not all of the above as type 1 does not maintain the historical data
Hello Rohish, Thank you for taking time and flagging this. Yes. The answer for the Python section is [2,4,6,8] There is apparently a typo. The initial question i prepared was supposed to have ** instead of * so that mistake occurred in the solutions. As per data modeling section as well, Yes, you're right! The best answer should be B) Type 2: Adding a new row with a timestamp, if the question is specifically asking for the best technique for tracking historical changes in a dimensional table. Both the corrections have been made.
Answer for python and data modeling is incorrect.
In python, lambda x: x*2 return
[2, 4, 6, 8] not [1, 4, 9, 16]
In Data modeling section, the correct answer is Type 2: Adding a new row with a timestamp not all of the above as type 1 does not maintain the historical data

You’re welcome 🙂!
Thank you for flagging. Il look into this and get back.
Both of the post has direct solution and explanation. It does not have 4 options for a quiz, not sure if it's way you want to put
