A won't really help with filtering, just checking.

Wait, why not just fix the corrupt data instead of filtering it out?

I think C could work too, but B seems more straightforward.

Partitioning sounds like it could work, but I feel like it might be overkill for just filtering out 2% of corrupt data.

I practiced a similar question where we had to clean data in a pipeline. I think using a ParDo transform was the solution there too.

I'm not entirely sure, but I think a SideInput might complicate things. We just need to filter out the bad data directly.

I remember something about using ParDo for filtering data in Dataflow. It seems like the right approach to discard corrupt elements.

I agree, the Process Builder seems like the way to go here. I'd create a single Process that checks the criteria and then takes the appropriate actions based on the results.

Hmm, I'm a bit confused on this one. I'll have to think it through carefully.

Okay, I think I've got this. Based on the question, the Azure Sentinel Contributor role seems like the best fit. It allows the security analyst to edit the queries of custom workbooks, which is exactly what the requirement is asking for. And it follows the principle of least privilege since it's a more specific role than something like Security Administrator.
