51% attack is more about control, not chain length.

A makes the most sense, but I see the confusion.

Wait, are we sure it's not C? Double-spend sounds like it could fit.

I think it's actually B, long-range attacks are sneaky.

Definitely A, selfish mining is all about that chain length!

I'm pretty sure the answer is C. Performing a forced takeover on Node01 should allow Node02 to serve data while we figure out what's wrong with Node01.

Hmm, I'm a bit unsure about this one. I know we need to set up some kind of category codes, but I'm not sure which ones would be the best fit for this requirement. I'll need to think it through carefully.

I think the key here is that the question specifies "no other configuration". That makes me think it's probably in a more specialized file, like mlag-config or api-config.
