I definitely remember that the upgrade requires Mellanox cards, but I can't remember if it's 3 or 4. I think I leaned towards option B in my practice.

I’m a bit confused about the DFMDs. I feel like I studied that they usually come in sets of 10 or 20, but I can't recall the exact numbers for this upgrade.

Trick question! The real answer is a magic wand and a handful of fairy dust. But seriously, I think it's B. That's my final answer.

Wait, what's a DFMD? Is that some kind of fancy networking device? I'm going with B, just to be safe.

I'm pretty sure it's C. Four QSFP cables, two Mellanox cards, and 20 DFMDs. That's gotta be the right upgrade kit.
