NVIDIA AI Infrastructure : NCP-AII Exam Questions

During BCM cluster setup, an engineer must configure bonded network interfaces on DGX nodes for high availability. Which cmsh command sequence properly configures a bond0 interface with two physical NICs?

• A.
  
• B.
  
• C.
  
• D.
  

An AI infrastructure team upgrades a training cluster from PCIe-only GPU servers to HGX systems with NVLink and NVSwitch. Single-GPU benchmark results remain unchanged, but multi-GPU training jobs complete significantly faster. Which workload characteristic most directly benefits from the new architecture?

• A. Kubernetes control plane scheduling latency
• B. Frequent peer-to-peer communication and collective operations among GPUs
• C. Sequential CPU-intensive preprocessing before model execution
• D. Local NVMe read performance for training datasets

A cluster administrator is preparing to update the firmware on a DGX H100 system, including the GPU tray (baseboard). What is the correct sequence of steps to perform a safe and successful firmware upgrade?

• A. Perform a cold reset, stop all GPU activity, update and reboot the BMC, update motherboard and tray components, and verify completion.
• B. Update the GPU tray first, then the motherboard tray, and reboot the BMC after all updates are complete.
• C. Stop all GPU activity, update and reboot the BMC, update motherboard and tray components, perform a cold reset, and verify completion.
• D. Update the BMC and skip the GPU tray and motherboard tray updates if the system appears healthy.

You are a network administrator responsible for configuring an East-West (E/W) Spectrum-X fabric using SuperNIC. The Bluefield 3 devices in your network should be a set to NIC mode with RoCE enabled to optimize data flow between servers. You have access to the Spectrum-X management tools and the necessary documentation. You need to use specific configuration commands to achieve this setup. Which of the following steps and commands are necessary to configure the Bluefield 3 devices in NIC mode for the E/W Spectrum-xX fabric using SuperNIC?
(Choose two.)

• A. Use the command sudo mixconfig -d /dev/mst/<device> set LINK_TYPE_P1=2 to enable Ethernet on the Bluefield 3 devices.
• B. Use the command sudo mixconfig -d /dev/mst/<device> set DISABLE_SPECTRUM_X=1 to reduce overhead.
• C. Use the command sudo mixconfig -d /dev/mst/<device> set DPU_MODE=1 to set up the Bluefield
  3 devices in DPU (Data Processing Unit) mode.
• D. Use the command sudo mixconfig -d /dev/mst/<device> set
  INTERNAL_CPU_OFFLOAD_ENGINE=1 to configure the SuperNIC to operate in NIC mode.

You are leading a project to enhance the energy efficiency of a data center that heavily relies on AI workloads. NVIDIA suggests moving beyond traditional metrics like Power Usage Effectiveness (PUE) to better capture the efficiency of modern data centers. Which strategy should you prioritize to develop more accurate energy-efficiency metrics?

• A. Use watts-used as the primary measure of efficiency, as it accurately reflects the power input at any given time.
• B. Use Power Usage Effectiveness as the primary metric while supplementing it with additional measures of useful work done per unit of energy.
• C. Develop benchmarks tailored to specific workloads, such as MLPerf for AI applications, to better understand energy use in real-world scenarios.
• D. Focus on integrating kilowatt-hours into existing metrics to better reflect the actual energy used for productive work.
