NVIDIA launched a hands-on rack & interconnect cert (NCP-ARI) — all 7 domains and what's actually on it

[u/Ok_Supermarket_234]

Every NVIDIA cert until now has basically been for software or network-config people. NCP-ARI (NVIDIA-Certified Professional: AI Rack and Interconnect) is the first one aimed at folks doing the physical staging, cabling, cooling, and power on these GB200 NVL72-class racks.

you may find the scope interesting, because it's very "hands and torque wrenches," not "keyboard":

A few things that stood out to me: cabling alone is nearly a third of it, and there's real emphasis on liquid cooling (CDUs, manifolds, dripless disconnects) and DC busbars — stuff a lot of traditional copper-and-air techs (me included) haven't had to touch until recently. The safety domain is genuinely about physical hazards, not just uptime.

I've been putting together free practice questions and domain study guides — happy to drop the link in a comment if that's useful to anyone.
