A DGX server reports degraded performance and storage alerts. How would you use NVSM and nvidia-smi to troubleshoot both system and GPU issues?

A. Use nvsm show health for a system health summary, nvsm show storage for storage issues, and nvidia-smi -q to get detailed GPU information.

B. Run nvsm collect-stats to gather logs, use lsblk to understand if there are storage problems, and nvidia-smi -q to get detailed GPU information.

C. Start by issuing nvidia-smi -L to list GPUs, followed by nvsm --refresh to clear all alerts, and nvidia-smi -q to get detailed GPU information.

D. Run nvsm reset to restore system health, then use nvidia-smi --fix for automatic GPU repairs and status recovery.

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 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-X fabric using SuperNIC? (Pick the 2 correct responses below)

A. Use the command sudo mlxconfig -d /dev/mst/< device > set LINK_TYPE_P1=2 to enable Ethernet on the Bluefield-3 devices.

B. Use the command sudo mlxconfig -d /dev/mst/< device > set DISABLE_SPECTRUM_X=1 to reduce overhead.

C. Use the command sudo mlxconfig -d /dev/mst/< device > set INTERNAL_CPU_OFFLOAD_ENGINE=1 to configure the SuperNIC to operate in NIC mode.

D. Use the command sudo mlxconfig -d /dev/mst/ set DPU_MODE=1 to set up the Bluefield-3 devices in DPU mode.
