Wait, are we talking about a port as in a harbor or a computer port? I'm picturing a bunch of ships downloading data from DataNodes now.

I'm not sure about option B, doesn't the NameNode just coordinate the file locations? Seems like an unnecessary step.

I'm not sure, but I think the answer is C because it seems logical for the client to connect to the node with the replica if there's a failure.

I disagree, I believe the answer is D because multiple clients should be able to read the same file data at the same time.
