N+M, huh? Sounds like a new math equation I need to learn. Maybe I can get bonus points if I solve for X while I'm at it.

Alright, let's focus here. The key is understanding the principle of Erasure code N+M. I think the correct answer is D, since the system should support up to N hard disk failures, not just M.

Haha, 'wong'? I think the person who wrote this question needs to brush up on their English. Maybe they're trying to be funny, but it's a bit cringeworthy.

Okay, let me think this through. If the system stores N+M data blocks in parallel, then it should be able to tolerate up to M disk failures, not just N. That must be the 'wong' statement.

I think you're right. The system should be able to tolerate up to M disk failures, not just N.
