Suggested Answer: B

Tabular Editor is an advanced tool for editing Tabular models outside of Power BI Desktop that allows you to script out changes and apply them across multiple columns or tables. To accomplish the task programmatically, you would:

Open the model in Tabular Editor.

Create an Advanced Script using C# to iterate over all tables and their respective columns.

Within the script, check if the column name ends with 'Key'.

For columns that meet the condition, set the properties accordingly: IsHidden = true, IsNullable = false, SummarizeBy = None, IsAvailableInMDX = false.

Additionally, mark the column as a key column.

Save the changes and deploy them back to the Fabric tenant.

I'm going with Option B, because why not? It's like a game of 'Where's Waldo?' for your data, and Spark's 'broadcast' feature is like the winning lottery ticket.

Option A all the way, baby! Spark's 'join()' method is the way to go. It's like a dance party for your data, and you're the DJ!

I'm not sure, this seems tricky. But I'll go with Option C just to be safe. Can't go wrong with a good old pandas merge, right?
