Question 1
An InfiniBand server stops working, and a system administrator runs the "ibstat" command that provides the following output: CA 'mlx5_1' CA type: MT4115 Number of ports: 2 Firmware version: 10.20.1010 Hardware version: 0 Node GUID: 0x0002c90300002f78 System image GUID: 0x0002c90300002f7b Port 1: State: Initializing Physical state: Linkup Rate: 100 Base lid: 0 LMC: 0 SM lid: 0 Capability mask: 0x0251086a Port GUID: 0x0002c90300002f79 Link layer: InfiniBand What is the cause of the issue?
A. The HCA port is faulty.B. There is no running SM in the fabric.
C. The neighboring switch port is faulty.
D. The cable is disconnected.
Question 2
During multi-node HPL burn-in, GPUs show uneven utilization. Which configuration ensures balanced workload distribution?
A. Enable HPL_USE_NVSHMEM=1 for shared memory accelerationB. HPL_RUN_GEMM_TESTS to skip validation
C. Set --gpu-affinity and --cpu-affinity to align GPU and NUMA nodes
D. HPL_OOC_TILE_M to 8192 for larger blocks
Question 3
Your tasked with updating both NVIDIA GPU drivers and DOCA drivers on a set of servers used for AI workloads. The environment previously had an older driver stack and custom kernel modules. What is the most important step to successfully upgrade the drivers without causing conflicts?
A. Update the GPU driver leaving the DOCA and OFED drivers unchanged as long as they are detecting the hardware properly.B. Validate the driver version post-install since the fresh install will overwrite the legacy drivers.
C. Keep the older driver running alongside the new version in case you need to roll back the upgrade.
D. Uninstall all existing GPU and DOCA-related drivers and associated kernel modules before the new install.
Question 4
An administrator is configuring node categories in BCM for a DGX BasePOD cluster. They need to group all NVIDIA DGX H200 nodes under a dedicated category for GPUaccelerated workloads. Which approach aligns with NVIDIA's recommended BCM practices?
A. Assign nodes to the ’login" category to simplify Slurm integration.B. Create a new "dgx-h200" category, assign all DGX H200 nodes to it.
C. Use the existing "dgxnodes" category without modification, as it is preconfigured for all DGX systems.
D. Avoid categories and configure each DGX node individually via CLI.
Question 5
One of the nodes in a cluster is not running as fast as the others and the system administrator needs to check the status of the GPUs on that system. What command should be used?
A. lspci | grep NVIDIAB. nvidia-smi
C. nvidia-gpu-status
D. iblinkinfo
