The NVIDIA Certified Professional: AI Infrastructure (NCP-AII) is a professional-level credential that validates hands-on expertise in deploying, configuring, validating, and troubleshooting advanced NVIDIA AI infrastructure. The certification covers the full lifecycle of building a production-ready GPU cluster, including hardware bring-up of NVIDIA HGX systems, BMC and firmware configuration, InfiniBand and Ethernet networking topology, storage integration, and cluster orchestration using platforms such as Base Command Manager with Slurm, Enroot, and Pyxis. Candidates are expected to demonstrate proficiency with GPU-specific technologies including Multi-Instance GPU (MIG) for workload partitioning, BlueField DPU configuration for networking offloads and secure multi-tenancy, and NVIDIA NVLink/NVSwitch interconnects.
The certification also places significant emphasis on cluster verification and performance validation, requiring proficiency with tools such as HPL (High-Performance Linpack), NCCL (NVIDIA Collective Communications Library) tests, and ClusterKit. This distinguishes the NCP-AII from more conceptual credentials — it is explicitly designed to test the practical skills needed to stand up and certify an AI data center cluster from rack-level physical installation through software-stack validation and performance benchmarking.
The NCP-AII is designed for data center professionals who build and maintain GPU-accelerated infrastructure for AI workloads. Primary target roles include data center administrators, system administrators, infrastructure engineers, network engineers, and storage administrators who work directly with NVIDIA hardware. Solution architects and pre-sales engineers who need to validate hands-on knowledge of NVIDIA AI infrastructure deployments are also well-suited for this credential.
Candidates should already be working in a data center environment with direct exposure to NVIDIA compute platforms. This is not an entry-level credential — it targets practitioners with meaningful operational experience who are looking to formalize and validate their expertise in large-scale GPU cluster deployment and management.
NVIDIA recommends that candidates have two to three years of operational experience working in a data center with NVIDIA hardware solutions. Candidates should be capable of independently deploying all components of a data center infrastructure in support of AI workloads, including GPU servers, high-speed networking, and storage systems. There are no formal prerequisites or mandatory prior certifications required to register for the exam.
Familiarity with Linux system administration, networking fundamentals (InfiniBand and Ethernet), and container-based workload execution is strongly recommended. Candidates who lack hands-on experience may benefit from completing the associate-level NVIDIA Certified Associate: AI Infrastructure and Operations (NCA-AIIO) credential before attempting the NCP-AII, as it covers foundational concepts that the professional exam assumes as prerequisite knowledge.
The NCP-AII exam consists of approximately 70 questions and must be completed within a 120-minute time limit. The exam is delivered online via remote proctoring through the Certiverse platform, making it accessible without requiring travel to a testing center. Questions are primarily multiple-choice and scenario-based, testing practical knowledge of NVIDIA infrastructure deployment and validation workflows. The exam is available in English and Simplified Chinese.
The exam costs $400 USD and results are reported as pass/fail. Upon passing, candidates receive a digital badge (delivered via Credly) typically within 24 hours, along with an optional printed certificate. The certification remains valid for two years from the date of issuance, after which recertification requires retaking the current version of the exam. A minimum passing score of approximately 70% correct responses is required, though NVIDIA does not publish a specific numeric threshold.
The NCP-AII credential aligns directly with some of the most in-demand technical roles in the current AI infrastructure market, including AI Infrastructure Engineer, GPU Cluster Administrator, MLOps Engineer, HPC Systems Engineer, and Solutions Architect for AI data centers. Organizations deploying NVIDIA Hopper and Blackwell GPU clusters — including cloud providers, hyperscalers, enterprise AI teams, and HPC facilities — increasingly list NVIDIA professional certifications as a preferred or required qualification. Salary ranges for professionals in these roles typically fall between $125,000 and $175,000 at the mid-level, with senior infrastructure architects exceeding $200,000 annually in competitive markets.
Within NVIDIA's certification pathway, the NCP-AII sits at the professional tier alongside the NCP-AIO (AI Operations), with both credentials building on the associate-level NCA-AIIO foundation. The NCP-AII is specifically differentiated toward cluster build and bring-up roles, while the NCP-AIO targets ongoing operations, monitoring, and optimization. Earning the NCP-AII demonstrates a depth of hands-on capability — particularly around cluster verification with HPL and NCCL — that is difficult to demonstrate through résumé experience alone, making it a meaningful differentiator for practitioners competing for roles at organizations running large-scale AI infrastructure.
5 sample questions with answers and explanations. The full bank has 1,046 questions, enough for 16 full-length practice exams.
Preview — answers shown1. A data center engineer is configuring a new DGX H100 system and needs to verify the NVLink topology. When running nvidia-smi topo -m, the output shows 'NV18' between GPU pairs within the same NVSwitch domain. What does this NV18 designation indicate?
Explanation
The NV18 designation in nvidia-smi topo output indicates 18 NVLink connections between GPU pairs. In the DGX H100 system with fourth-generation NVLink, each link provides 50 GB/s bidirectional bandwidth, so 18 links provide 900 GB/s total bidirectional bandwidth. This full NVLink connectivity enables efficient GPU-to-GPU communication for distributed training workloads.
2. A cluster administrator notices that XID errors 45 are appearing intermittently across multiple GPUs in a DGX H100 system during large model training. What type of issue does XID 45 indicate?
Explanation
XID error 45 indicates a preemptive context switch, which occurs when the GPU scheduler interrupts a running kernel to allow another context to execute. This is normal behavior when multiple applications share a GPU or when compute preemption is enabled. If seen frequently during dedicated training jobs, it may indicate unintended workloads running on the same GPUs. This is not a hardware error but rather a scheduling event that can impact performance if unexpected.
3. A cluster administrator runs HPL-MxP (Mixed Precision) benchmark and achieves significantly higher FLOPS than traditional HPL but observes periodic performance drops every 15-20 minutes. GPU temperatures remain stable. What should be investigated?
Explanation
HPL-MxP achieves high FLOPS through Tensor Core utilization but may stress GPU power delivery differently than traditional workloads. Periodic performance drops (15-20 minutes) suggest boost clock cycling or power management behavior as the GPU manages thermal and power budgets over time. Modern GPUs dynamically adjust boost behavior based on sustained power consumption patterns.
4. A performance engineer is reviewing NVLink Switch capabilities. What is the non-blocking switching capacity of the NVLink 5 Switch?
Explanation
The NVIDIA NVLink 5 Switch features 144 NVLink ports with a non-blocking switching capacity of 14.4 TB/s. This is the first rack-level switch chip capable of supporting up to 576 fully connected GPUs in a non-blocking compute fabric, enabling massive scale-out GPU clusters.
5. A data center engineer is documenting rack elevation diagrams for a DGX SuperPOD installation. According to NVIDIA reference architecture, what rack unit position is recommended for InfiniBand leaf switches in a standard deployment?
Explanation
NVIDIA reference architecture typically places InfiniBand leaf switches at the Top of Rack (ToR) position. This provides efficient cable management with short, consistent cable lengths to DGX systems below, while uplinks to spine switches (in dedicated network racks or top of row) have a clear, organized path. ToR placement also provides good accessibility for switch management and cable changes. Weight distribution is not a concern for typical switch weights.
