NCP-AIN sample questions

2 questions from the NCP-AIN practice set, with the answer and explanation.

  1. Question 1
    Which NVIDIA component is a data processing unit (DPU) that offloads networking, storage and security work from the host CPUs in an AI factory design?
    • A.
      BlueField DPU
    • B.
      Spectrum-X leaf switch
    • C.
      NVLink Switch tray
    • D.
      Out-of-band management switch
    Show answer

    Correct answer:

    • A.
      BlueField DPU

    Explanation

    BlueField is NVIDIA's DPU family, and it runs networking, storage and security services on its own Arm cores so the host CPU is not burdened. A Spectrum-X leaf switch forwards packets between servers but does not host those offloads, which makes it the most tempting distractor.
  2. Question 2
    What defines a rail-optimized topology for multi-node GPU training?
    • A.
      All GPUs in one server connect to a single switch port group
    • B.
      GPUs with the same index on each node share one rail switch
    • C.
      Storage traffic is isolated onto dedicated rails
    • D.
      Rails carry only out-of-band management traffic
    Show answer

    Correct answer:

    • B.
      GPUs with the same index on each node share one rail switch

    Explanation

    In a rail-optimized design, the GPU at a given index in every node attaches to the same rail (leaf) switch, so collective operations between matching GPUs stay on one switch layer. Grouping all GPUs of one server onto one switch, the first option, describes a simple node-local layout rather than rail alignment.
