Haha, good one! I'll make sure to keep my notes in a Fabric notebook, just like the one in the question. Definitely the most efficient way to study for this exam.

Exactly! I'm going with option C. It just makes the most sense for this scenario. Now, if only the exam had a question about the best way to store my exam notes... *wink wink*

Ooh, good catch! Option C does seem like the winner here. Broadcast joins are great for minimizing data movement, especially when one of the DataFrames is small enough to fit in memory on each partition.
