I think the correct answer is B. The pound sign is indeed an invalid character, so only three files will be processed.

But what about E? Could it be just one file processed due to the naming restriction?

I'm leaning towards B, since the pound sign is not allowed in file names.

I disagree, I believe the answer is C because files with leading periods or underscores are ignored.

Okay, let's think this through step-by-step. HDFS file names, special characters, hidden files... I think I've got this. *rubs hands together*

Ugh, this is the kind of question that makes me wish I had a cheat sheet handy. I'm going to have to rely on my instincts and pray I don't mess this up.

I don't know, I kind of like these types of questions. It shows they're really testing our understanding of the underlying system. I'm going to give it my best shot.

Oh man, I hate questions like this! It's like they're testing our knowledge of HDFS arcane rules rather than our actual skills. Can't they just ask us something more straightforward?

Hmm, I think it's a valid question, but it feels a bit like they're trying to trip us up with the file naming conventions. I'm going to have to really think this through.
