Part of HOW TO // AI — CERT — practice questions for NVIDIA, AWS, and Microsoft AI certifications.
The NCA-AIIO (NVIDIA-Certified Associate: AI Infrastructure and Operations) is NVIDIA’s entry-level certification for people who run, support, or sell AI infrastructure — data center technicians, DevOps and networking engineers, IT managers, sysadmins, and solution architects. The exam is 50 questions in 60 minutes, taken online with remote proctoring, and costs $125. It’s pass/fail (NVIDIA doesn’t report a score), and the credential is valid for two years.
Practice questions are the highest-leverage way to prepare: they show you how concepts get tested, expose the gaps you didn’t know you had, and make the real exam feel familiar. The free quiz below works like the real thing — multiple choice, one correct answer — and every question comes with an explanation of why the answer is right, which is where the actual studying happens.
What’s on the NCA-AIIO exam
NVIDIA’s published exam blueprint has three domains. Our question set mirrors these weights, so your practice score roughly tracks how the real exam distributes its questions:
| Domain | Exam weight | What it covers |
|---|---|---|
| AI Infrastructure | 40% | GPU hardware and sizing, clusters, data center networking (InfiniBand, RoCE), power and cooling, DPUs, on-prem vs cloud |
| Essential AI Knowledge | 38% | AI vs ML vs DL, training vs inference, GPU vs CPU architecture, the NVIDIA software stack (CUDA, NGC, TensorRT, Triton), AI use cases |
| AI Operations | 22% | Cluster orchestration and job scheduling (Slurm, Kubernetes), GPU monitoring (DCGM), virtualization (MIG, vGPU) |

How to prepare for the NCA-AIIO
NVIDIA recommends its self-paced AI Infrastructure and Operations Fundamentals course (about 7 hours) and suggests “a basic understanding of data center infrastructure” going in. A study loop that works: read the official exam guide on NVIDIA’s certification page, take a practice set like the one above, then study the domains where you missed questions rather than re-reading everything. If you’re newer to the AI side of the exam, our plain-English AI glossary and explainer on how AI models actually work cover the Essential AI Knowledge concepts in beginner-friendly terms.

Frequently asked questions
What is the NCA-AIIO certification?
NCA-AIIO (NVIDIA-Certified Associate: AI Infrastructure and Operations) is NVIDIA's entry-level certification covering the foundations of AI computing infrastructure — GPU hardware, data center networking, the NVIDIA software stack, and cluster operations. It's aimed at IT professionals, data center staff, DevOps and networking engineers, and solution architects who work with or around AI infrastructure.
How many questions is the NCA-AIIO exam and how long is it?
The exam is 50 questions in 60 minutes, taken online with remote proctoring. It costs $125 and is currently offered in English. That pace — just over a minute per question — is why timed practice matters.
What score do I need to pass the NCA-AIIO?
NVIDIA doesn't publish a passing score: the exam is pass/fail and you won't receive a numeric score. Some prep sites claim a 70% threshold, but that figure isn't confirmed by NVIDIA. Aim to consistently score 80%+ on practice sets so you have margin on exam day.
What topics are on the NCA-AIIO exam?
Three domains: AI Infrastructure (40%) — GPU hardware, clusters, data center networking, power and cooling, DPUs; Essential AI Knowledge (38%) — AI/ML/DL concepts, training vs inference, GPU vs CPU architecture, the NVIDIA software stack; and AI Operations (22%) — orchestration and scheduling, GPU monitoring, and virtualization.
How hard is the NCA-AIIO and how should I prepare?
It's an associate-level exam — broad rather than deep, with straightforward multiple-choice questions. Most candidates prepare with NVIDIA's self-paced AI Infrastructure and Operations Fundamentals course (about 7 hours) plus practice questions. Study the domains where practice reveals gaps instead of re-reading everything.
How long is the NCA-AIIO certification valid?
Two years from the date you earn it. To stay certified after that, you retake the current version of the exam.
