[NEW] NVIDIA Certifications: AI Infrastructure

Physical Layer Management (5%): Configuring BlueField DPU platforms, verifying high-speed cabling, and implementing Multi-Instance GPU (MIG) setups.

Control Plane Installation and Configuration (19%): Installing Base Command Manager (BCM) in High Availability, managing DOCA drivers, and utilizing the NVIDIA Container Toolkit.

Cluster Test and Verification (33%): Executing HPL benchmarks, validating NCCL performance, and conducting rigorous "burn-in" testing via ClusterKit.

Troubleshoot and Optimize (12%): Identifying hardware faults in GPUs or networking cards and performing subsystem mastering back end performance optimization practice tests.

B. To check the physical disk read/write speeds of the storage array.

C. To validate the inter-GPU communication performance across the high-speed fabric.

D. To update the BIOS version of the head node automatically.

E. To monitor the RPM of the server chassis fans under idle load.

F. To install the NVIDIA Container Toolkit on all worker nodes.

Correct Answer: C

Explanation:

A (Incorrect): Single GPU compute is usually measured by benchmarks like HPL or simple CUDA kernels, not NCCL.

B (Incorrect): Storage performance is typically validated using tools like FIO, not NCCL.

D (Incorrect): NCCL is a communication library, not a firmware update utility.

E (Incorrect): Fan monitoring is handled by the BMC or IPMI, not a communication library.

F (Incorrect): NCCL is a library used by applications; it does not perform software installations.

Question 2: Which feature should be used to partition a single NVIDIA A100 or H100 GPU into multiple isolated instances for smaller AI workloads?

B. Multi-Instance GPU (MIG)

C. Base Command Manager (BCM)

D. GPUDirect Storage

E. BlueField DPU Offloading

F. NVIDIA DOCA SDK

Correct Answer: B

Explanation:

A (Incorrect): NVLink is for connecting multiple GPUs together, not partitioning one.

C (Incorrect): BCM is a management software for clusters, not a GPU hardware partitioning feature.

D (Incorrect): GPUDirect Storage speeds up data transfer between storage and GPU memory.

E (Incorrect): DPUs offload networking and security tasks, not GPU compute partitioning.

F (Incorrect): DOCA is the software framework for programming DPUs.

Question 3: When a "GPU Fallen Off Bus" error is detected during a stress test, which troubleshooting step is most appropriate for a Professional AI Infrastructure engineer?

B. Reinstalling the OS from scratch immediately.

C. Checking the GPU power cables, reseating the card, and reviewing the DCGM logs.

D. Changing the IP address of the management network.

E. Deleting the NGC CLI configuration file.

F. Disabling the NVIDIA Container Toolkit.

Correct Answer: C

Explanation:

A (Incorrect): Higher temperatures generally decrease hardware stability.

B (Incorrect): This is an extreme measure that doesn't address potential hardware faults.

D (Incorrect): Management IP addresses are unrelated to the PCIe bus stability of a GPU.

E (Incorrect): NGC CLI is a software tool for downloading containers and does not affect hardware bus connectivity.

F (Incorrect): The toolkit manages containers; it does not cause a GPU to physically drop off the bus.
