How hard is the NCP-AIN exam? +
Hard, because it demands professional depth in two fabrics at once. NVIDIA Spectrum (Ethernet) and InfiniBand are each 30%. Strong Ethernet engineers often lack InfiniBand subnet management, PKeys and SHARP, while InfiniBand specialists stumble on RoCE, PFC, ECN and BGP-EVPN. Troubleshooting Tools adds another 20%, with questions asking which specific command isolates a fabric problem.
What is the NCP-AIN exam format, and what's changing with lab exercises? +
NCP-AIN has 70 to 75 questions with a two-hour limit, taken online in English through NVIDIA's exam platform. NVIDIA announced it is adding hands-on lab exercises from November 1, with the fee rising from $400 to $500 at that point. Check the exam page for the current format before you book, and prepare to configure and verify a fabric yourself, not just answer multiple choice.
What is the passing score for NCP-AIN? +
NVIDIA does not publish the passing score for NCP-AIN; results are pass or fail. With two 30% fabric domains, a weak side - InfiniBand or Spectrum-X Ethernet - is usually what causes a fail. Aim for solid practice results in both fabrics and in Troubleshooting Tools rather than a high overall average.
What experience does NCP-AIN expect and how long is it valid? +
There are no formal prerequisites, but NVIDIA recommends 2 to 3 years of hands-on data center experience, ideally with NVIDIA networking hardware. The domains are Spectrum Networking 30%, InfiniBand Networking 30%, Troubleshooting Tools 20%, Automation and Configuration 10%, AI Data Center Design and Optimization 5% and Kubernetes Integration 5%. The certification is valid for two years, and you recertify by retaking the exam.
Which troubleshooting tools and commands does NCP-AIN test? +
Expect ibdiagnet, ibstat and ib_write_bw for InfiniBand, UFM for fabric management, NetQ for Ethernet visibility and What Just Happened for packet-drop analysis. Questions give a symptom and ask which tool or command isolates it, so you need to know what each one reports, not just what it's for. Automation questions use NVUE, Cumulus Linux and Ansible rather than other vendors' CLIs.
How long should I prepare for NCP-AIN? +
Experienced network engineers usually need 6 to 10 weeks, most of it on whichever fabric they use less. Hands-on time matters more than ever with lab exercises being added. NVIDIA Air lets you build simulated Cumulus Linux networks for free, which is a practical way to get comfortable with NVUE syntax if you don't have Spectrum switches available.
