You're researching the DGX OS (NVIDIA's operating system for DGX systems) and you want to know its foundation. Which Linux distribution does DGX OS build upon?
Select an answer to reveal the explanation.
Short Explanation
NVIDIA built DGX OS on top of Ubuntu. They enhanced it with drivers, CUDA libraries, and AI-focused tools. It's not Red Hat, SLES, or CentOS — it's Ubuntu.
Full Explanation
DGX OS is NVIDIA's customized Linux distribution for DGX systems. Instead of shipping raw hardware and leaving users to figure out driver installation and software setup, NVIDIA pre-configures everything on Ubuntu. This Ubuntu base is then enhanced with: NVIDIA drivers optimized for DGX hardware, CUDA toolkit, cuDNN, NCCL, DCGM, and various other AI libraries. The result is a turnkey system — users unbox the DGX, power it on, and they have a fully functional AI compute platform. NVIDIA chose Ubuntu because of its broad adoption, good hardware support, and active community. This is a specification detail about DGX OS that certification exams test. It's not a tricky question; it's testing knowledge.
