Three of the 170 questions in this pack

Question 1

A system engineer needs to set the vGPU scheduling behavior for all GPUs to share the scheduling equally with the default time slice length.

What command should be used?

  1. esxcli system module parameters set -m nvidia -p “NVreg_RegistryDwords=RmPVMRL=0x00”
  2. esxcli system module parameters set -m nvidia -p “NVreg_RegistryDwords=RmPVMRL=0x01”
  3. esxcli graphics module parameters set -m nvidia -p “NVreg_RegistryDwords=RmPVMRL=0x01”
  4. esxcli system module parameters set -m nvidia -p “NVreg_RegistryDwords=FRL=0x01”
Show answer and explanation

Correct answer: B. esxcli system module parameters set -m nvidia -p “NVreg_RegistryDwords=RmPVMRL=0x01”

On VMware vSphere, the vGPU scheduling policy for all GPUs is set through the RmPVMRL registry key, passed to the nvidia kernel module with esxcli system module parameters set -m nvidia -p followed by the NVreg_RegistryDwords string. A value of 0x01 selects the equal share scheduler with the default time slice length, so every running vGPU receives an equal share of GPU processing time. A value of 0x00 selects the best effort scheduler, which is the default behavior. The new setting takes effect after the ESXi host is rebooted.

Why the other options are wrong

  • A. RmPVMRL=0x00 selects the best effort scheduler, which does not divide GPU time equally among vGPUs.
  • C. The esxcli graphics namespace does not set kernel module parameters, which are configured under esxcli system module parameters.
  • D. FRL refers to the frame rate limiter and is not the registry key that selects the vGPU scheduling policy.

Question 2

During a multi-day NeMo burn-in, intermittent “GPU fell off bus” errors occur.

Which diagnostic approach isolates hardware faults?

  1. Run DCGM diagnostics alongside burn-in to monitor GPU health metrics
  2. Switch from BERT to GPT models for simpler computations
  3. Enable HPL_USE_NVSHMEM for alternative memory sharing
  4. Reduce blocksize to 500MB to lower memory pressure
Show answer and explanation

Correct answer: A. Run DCGM diagnostics alongside burn-in to monitor GPU health metrics

A GPU that falls off the bus is a hardware or platform level fault, so the right approach is to collect GPU health data while the stress is applied. Running DCGM diagnostics and health monitoring alongside the NeMo burn-in records Xid errors, PCIe and NVLink errors, memory errors, temperatures and power behavior for each GPU. Correlating these readings with the moment of each failure shows whether a specific GPU, slot or board is at fault, which allows the affected component to be isolated and replaced instead of masking the symptom.

Why the other options are wrong

  • B. Changing the model being trained alters the workload but provides no data about which hardware component is failing.
  • C. HPL_USE_NVSHMEM is an HPL benchmark setting and has no role in diagnosing GPU faults during a NeMo burn-in.
  • D. Lowering memory pressure may hide the symptom but does not identify the failing GPU or component.

Question 3

An engineer needs to verify the current firmware versions of all components (ATF, BSP, NIC, UEFI) on a BlueField-3 DPU’s BMC.

Which Redfish API command provides this information?

  1. mstflint -d <device> query full
  2. curl -k -u root:<password> -X GET https://<bmc_ip>/redfish/v1/UpdateService/FirmwareList
  3. curl -k -u root:<password> -X GET https://<bmc_ip>/redfish/v1/UpdateService/FirmwareInventory
  4. mlxconfig -d <device> q
Show answer and explanation

Correct answer: C. curl -k -u root:<password> -X GET https://<bmc_ip>/redfish/v1/UpdateService/FirmwareInventory

The BlueField-3 BMC exposes the versions of the firmware components it manages through the standard Redfish UpdateService. A GET request to /redfish/v1/UpdateService/FirmwareInventory returns a collection with one member per component, such as the ATF, BSP (BlueField Board Support Package), NIC firmware, UEFI and the BMC itself, and each member reports its current version. Querying this endpoint with curl and the BMC credentials gives a single, authoritative view of all installed firmware versions, which is the standard check before and after a firmware update on the DPU.

Why the other options are wrong

  • A. mstflint queries the firmware of a single NIC device and is not a Redfish call to the BMC.
  • B. FirmwareList is not a resource defined under the Redfish UpdateService, so this request does not return the inventory.
  • D. mlxconfig queries device configuration parameters, not the firmware versions of the DPU components managed by the BMC.

What makes the NCP-AII hard

NCP-AII is the hands-on infrastructure exam in NVIDIA's professional tier: 70 to 75 questions in 120 minutes about standing up a GPU cluster from the crate to the first benchmark. It follows the deployment sequence rather than a topic list, and candidates who pass say the exam cares about the order you do things in, and about what the validation numbers should look like when the cluster is healthy.

Cluster Test and Verification is the biggest domain at 33%: full cluster validation with HPL and NCCL, NVLink and fabric bandwidth tests, cable and firmware checks, and burn-in using HPL, NCCL and NeMo, and what a failing result means. System and Server Bring-up follows at 31%, covering AI factory designs and topologies, the physical build with cables and transceivers, GPU and NVSwitch firmware management, and initial configuration of BMC, OOB and TPM.

Control Plane Installation and Configuration is 19%, covering Base Command Manager, the operating system, Slurm with Enroot and Pyxis, NVIDIA GPU and DOCA drivers, the Container Toolkit and the NGC CLI. Troubleshoot and Optimize is 12%, and Physical Layer Management, covering the BlueField network platform and Multi-Instance GPU partitioning, is 5%. HGX firmware upgrade order and the bring-up sequence are the questions most people report getting wrong.

About the exam

NCP-AII (NVIDIA-Certified Professional: AI Infrastructure) is an intermediate-level certification validating the ability to deploy, configure, test and optimise NVIDIA AI infrastructure: server bring-up, physical layer management, control plane installation, cluster test and verification, and troubleshooting and optimisation. NVIDIA recommends hands-on experience deploying NVIDIA GPU clusters.
