Sixteen crates of DGX H100 systems arrive on your loading dock on a Tuesday. Eight weeks later, someone expects a validated cluster: every NVLink at full width, every InfiniBand cable clean, HPL numbers matching the reference architecture, and a control plane that can provision nodes without a console cart. Everything between the crates and that handoff is what the NCP-AII exam tests.
NCP-AII (NVIDIA Certified Professional - AI Infrastructure) is the builder's certification in NVIDIA's infrastructure track. Where the associate-level NCA-AIIO validates that you understand AI infrastructure, NCP-AII validates that you can physically and logically stand it up: bring-up, firmware, fabric topology, control plane, and the test-and-verification gauntlet that separates a pile of expensive hardware from a production cluster.

Exam Quick Facts
What is NCP-AII?
The exam validates end-to-end deployment skill on the NVIDIA stack: DGX H100/H200 systems, NVLink and NVSwitch fabrics, BlueField DPUs, InfiniBand networking, and the software that turns racks into a cluster (Base Command Manager, Slurm, the container toolkit, and NGC).
An NCP-AII certified engineer can:
- Sequence a full cluster deployment from power and cooling validation through BMC configuration, firmware, OS provisioning, and fabric bring-up
- Validate NVLink topology, run NCCL communication tests across nodes, and execute HPL benchmarks that prove the cluster performs to spec
- Install and configure Base Command Manager as the control plane, including PXE provisioning and node images
- Diagnose hardware faults from DCGM output and Xid errors, and run component replacement procedures
- Configure MIG partitioning, vGPU, and BlueField DPU networking

Who Should Take This Exam
NVIDIA recommends two to three years of data center experience with NVIDIA hardware. The exam fits three profiles particularly well:
Data center engineers who deploy GPU systems. If your job includes racking DGX systems, running cables, updating firmware, and proving the result works, this exam formalizes exactly that workflow. The two largest domains (bring-up at 31%, test and verification at 33%) are two thirds of the exam and they are your day job.
HPC administrators moving to AI clusters. Cluster provisioning, Slurm, InfiniBand, and benchmark validation all transfer directly from traditional HPC. The NVIDIA-specific layer you add is the DGX platform, NVLink/NVSwitch fabrics, Fabric Manager, and the DCGM tooling.
Field and solutions engineers at NVIDIA partners. Integrators and OEM partners deploy these clusters for customers, and NCP-AII is the credential that maps to that delivery role.
If you operate clusters that someone else built, look at NCP-AIO instead: it covers administration, workload management, and troubleshooting of running infrastructure. And if you are earlier in the journey, the associate-level NCA-AIIO surveys the whole territory at lower depth and cost.
The Five Exam Domains
Two domains carry 64% of the exam, and both are hands-on hardware territory. The full topic list lives in the domains breakdown.
Core Topics
- •Single-node stress testing and burn-in
- •HPL benchmark execution and validation
- •NCCL testing for multi-node GPU communication
- •Cable signal verification and link integrity
- •NVLink topology validation
- •InfiniBand fabric testing
- •ClusterKit assessment tools
- •Firmware and software version confirmation

Career Impact and Salary
The AI build-out has made cluster deployment a scarce skill. Per ZipRecruiter, AI infrastructure engineers earn $107K-$141K in the 25th-75th percentile band, and senior engineers reach $155K-$200K with staff-level roles at $200K-$270K+. Deployment specialists sit at the front of that market because every new cluster (and enterprises are standing them up for the first time in large numbers) needs someone who has done a bring-up before.

The credential also compounds with its siblings. NCP-AII plus NCP-AIO covers a cluster's whole lifecycle, and adding NCP-AIN makes you the rare engineer who owns the fabric too.
How to Prepare
Start from the official material. NVIDIA recommends the self-paced AI Infrastructure and Operations Fundamentals course plus the instructor-led AI Infrastructure Professional Workshop. The workshop is the closest thing to a guided bring-up if your employer will fund it.
Get hands-on with the software layer. You cannot rack a DGX at home, and the exam knows it: the knowledge it tests around BCM, Slurm, containers, DCGM, and MIG can all be practiced on a single GPU node or cloud instance. This is where labs earn their keep.
Practice the software half of bring-up on real GPUs
Every lab runs on a live NVIDIA GPU. Deploy the GPU Operator stack, run DCGM health checks and auto-remediation, partition with MIG, profile with Nsight, and triage broken GPU pods: the operational muscle the exam assumes.
NVIDIA GPU Operator on k3s: Single-Node Kubernetes for GPU Workloads
Bring up a lightweight single-node Kubernetes cluster with the NVIDIA GPU Operator — k3s install, containerd wiring, Helm values, workload manifests with RBAC and ResourceQuota, plus a full runbook (validation plan, troubleshooting matrix, day-2 ops).
Inside the NVIDIA GPU Operator — From Helm to Workload-Ready
Walk the chain that turns a Helm install into the `nvidia.com/gpu` your workload requests. Inspect the cluster the way platform engineers do — node labels, capacity, RuntimeClass — and learn to attribute every piece of evidence to the GPU Operator component that produced it. Finishes with a Triage Day where three broken GPU pods each break a different chain link.
GPU Health Checks + Auto-Remediation
Build a production-grade GPU watchdog: multi-dimensional NVML health probe, rogue-process detection, auto-remediation that kills the offender and verifies recovery, then wire it up with Prometheus alerts and Kubernetes liveness probes.
GPU Observability: From nvidia-smi to a Production Monitoring Stack
Go from a raw NVML snapshot to a real monitoring pipeline: capture live GPU telemetry during a workload, diagnose a dataloader bottleneck from the utilization trace, and expose everything as a Prometheus /metrics endpoint.
GPU Sharing: Streams, MPS, MIG, and the Real Cost of Contention
Measure four ways to share a single GPU — CUDA streams, multi-process time-slicing, MPS, and MIG — and write the production artifacts (start scripts, k8s device-plugin ConfigMaps, MIG geometries) that turn 15%-utilized fleets into 80%-utilized ones.
Stuck-Pending Triage Day — Diagnose Any GPU Pod That Won't Run
The capstone NCA-AIIO operations lab. Walk the five-stage pod lifecycle (admission → scheduling → image pull → runtime → readiness), learn which `kubectl describe` field signals each stuck point, and finish by fixing four broken GPU pods, each broken at a different stage.
Learn the validation numbers. Test-and-verification is the biggest domain, and its questions reward knowing what healthy looks like: NCCL bus bandwidth in the expected range for the topology, HPL efficiency against the reference architecture, link widths at x16, NVLink counts per GPU generation. Build a mental table of reference values as you study.
