Nvidia NCP-AIN Certification Guide
About
About the Book
Pass the NVIDIA-Certified Professional: AI Networking (NCP-AIN) exam, and learn to run the networks behind AI factories.
GPU clusters live or die by their networks. This guide teaches the NVIDIA networking stack that connects them, from first principles to production operations. It follows every objective in NVIDIA’s published NCP-AIN exam blueprint.
One realistic running example, the Helix AI Factory, is built, configured, monitored and repaired across the whole book. It has an InfiniBand NDR training fabric and a Spectrum-X Ethernet fabric.
Inside you’ll find:
• AI factory architecture, NCCL collectives and rail-optimised topologies
• RDMA, InfiniBand transport and RoCEv2, with lossless Ethernet (PFC, ECN, DCQCN)
• Cumulus Linux and NVUE, adaptive routing, telemetry and BGP-EVPN multi-tenancy
• BlueField DPUs, SuperNICs and DOCA; NVIDIA Air digital twins; NetQ and What Just Happened
• The InfiniBand Subnet Manager, UFM high availability, partition keys, QoS, adaptive routing and SHARP
• The NVIDIA Network Operator for RDMA in Kubernetes
• Troubleshooting with ibdiagnet, perftest, nccl-tests, cl-resource-query, WJH and UFM health
• Automation with NVUE templates and Ansible
Built for learning: hundreds of technical diagrams, a hands-on lab and a troubleshooting scenario in every chapter, and about 1,000 original exam-style questions with explanations. It also has three timed 75-question mock exams, a final-week cram sheet, a command reference, a glossary and a flashcard deck.
Independent study guide. Not produced, sponsored or endorsed by NVIDIA Corporation. All practice questions are original.
