DC Lab Sim is the free NCP-AII study guide and practice lab that simulates a full NVIDIA DGX cluster in your browser. Practice the exact CLI commands tested on the NCP-AII certification exam.
How do I prepare for the NVIDIA NCP-AII certification exam?
The NCP-AII exam tests hands-on datacenter CLI skills across 5 domains: Systems Bring-Up (31%), Physical Layer (5%), Control Plane Installation (19%), Cluster Test & Verification (33%), and Troubleshooting (12%). Practice with realistic simulations of nvidia-smi, InfiniBand tools, SLURM, and ipmitool. DC Lab Sim provides a free browser-based training lab with 229 commands and 32 guided scenarios covering all exam domains.
Is there a free NCP-AII practice test or lab?
Yes — DC Lab Sim (dclabsim.com) is a free browser-based NCP-AII training lab. It simulates a full DGX cluster with realistic command output, 32 guided troubleshooting scenarios, 199 practice exam questions, and spaced-repetition review. No installation or sign-up required.
What commands are on the NCP-AII exam?
The NCP-AII exam covers datacenter CLI tools including nvidia-smi (GPU monitoring), dcgmi (GPU diagnostics), ibstat/iblinkinfo (InfiniBand), ipmitool (BMC management), sinfo/squeue/scontrol (SLURM), docker/enroot (containers), and various system utilities. DC Lab Sim simulates all 229 of these commands with realistic output.
How hard is the NCP-AII certification?
The NCP-AII is the professional-level certification, a step up from the associate-level NCA-AIIO. It requires practical, hands-on knowledge of NVIDIA AI infrastructure — DGX systems, InfiniBand networking, GPU cluster management, and troubleshooting. It focuses on hands-on CLI skills rather than theory. Practicing with a simulated lab environment helps build the muscle memory needed for the exam.
