NVIDIA AI Infrastructure Sample Questions (Q49-Q54):

NEW QUESTION # 49
You encounter an error during MIG instance creation using 'nvidia-smi' stating 'Insufficient GPU resources'. Which of the following could be the cause? (Select all that apply)

Answer: B,D,E

Explanation:
The 'Insufficient GPIJ resources' error indicates that the requested MIG instance creation cannot be fulfilled due to limitations in available resources (A) such as compute or memory. Outdated drivers (B) may not support the requested MIG configurations and hence can lead to resource management problems. When other instances or processes already consume all available resources (C), the operation can't continue. A GPU in a bad state might cause issues, but the specific error message points to resource exhaustion more directly. MIG does not bypass resource checks (E).


NEW QUESTION # 50
You are validating the environment of an NVIDIA GPU-accelerated data center during post-deployment checks. Which one action is essential to confirm that power and cooling are sufficient for the stable operation of NVIDIA DGX H100 systems?

Answer: B

Explanation:
Stable operation of high-density AI infrastructure like the DGX H100 requires strict adherence to power and thermal specifications. A single DGX H100 system can draw up to10.2kWunder peak load. Therefore, the most essential validation step is ensuring the electrical "infrastructure-to-server" handoff is healthy. This involves verifying that the system is connected to redundant PDUs (Power Distribution Units) capable of handling the amperage requirements without tripping breakers. UsingNVSM (NVIDIA System Management), an administrator must check that all six power supplies (PSUs) are functional and receiving nominal input voltage (typically 200V-240V). If a PSU reports sub-optimal input or a "Loss of Redundancy," the system may throttle performance or shut down unexpectedly during a heavy training run. Fans running at
100% (Option A) at all times would actually indicate an inefficient or failed cooling policy, as fans should dynamically scale based on thermals. Overclocking (Option B) is not supported or recommended for enterprise DGX systems, as they are already factory-tuned for the highest stable performance.


NEW QUESTION # 51
A system administrator noticed a failure on a DGX H100 server. After a reboot, only the BMC is available.
What could be the reason for this behavior?

Answer: A

Explanation:
On an NVIDIA DGX system, theBaseboard Management Controller (BMC)is an independent processor that runs even if the main CPU and Operating System fail to load. If a server reboots and the administrator can access the BMC web interface or IPMI console, but the OS (Ubuntu/DGX OS) does not load, the most likely cause is aboot disk failure. The DGX H100 uses NVMe drives in a RAID-1 configuration for the OS boot volume. If both drives in the mirror fail, or if the boot partition becomes corrupted, the system will hang at the BIOS or UEFI prompt, unable to find a bootable device. While failed power supplies (Option D) or network links (Option A) can cause issues, they would typically prevent the BMC from being reachable at all or prevent remote network traffic respectively. A GPU failure (Option C) would not stop the OS from booting; the system would simply boot with a degraded GPU count. Therefore, checking the storage health via the BMC "Storage" logs is the correct diagnostic step.


NEW QUESTION # 52
You are experiencing link flapping (frequent up/down transitions) on several InfiniBand links in your AI infrastructure. This is causing intermittent connectivity issues and performance degradation. What are the MOST likely causes of this issue, and what steps should you take to troubleshoot and resolve it? (Select TWO)

Answer: A,E

Explanation:
Link flapping is most commonly caused by physical layer issues (faulty cables, connectors, or transceivers) or configuration mismatches (link speeds or duplex settings). Troubleshooting should focus on inspecting the physical connections and verifying that the link speed and duplex settings are correctly configured on both ends of the link. While MTIJ issues and software bugs can cause network problems, they are less likely to directly cause link flapping. Excessive broadcast traffic can cause performance issues but is less likely to result in frequent link up/down transitions.


NEW QUESTION # 53
You have configured two lg.10gb MIG instances on an NVIDIAA100 GPU. You are running a deep learning training job on one instance and want to ensure that it cannot consume resources from the other MIG instance. Which mechanism ensures isolation between the two MIG instances at the hardware level?

Answer: E

Explanation:
MIG (Multi-lnstance GPU) provides hardware-level partitioning of the GPU. This means that each MIG instance has dedicated compute, memory, and memory bandwidth resources, ensuring strong isolation between the instances. CUDA MPS allows multiple processes to share a single GPU, but does not provide isolation. vGPU scheduling is for virtualized environments. Kubernetes resource quotas provide resource limits at the container orchestration level but do not provide hardware-level isolatiom Cgroups is a Linux kernel feature to limit, account, and isolate resource usage (CPU, memory, disk I/O, network, etc.) of process groups. It is often used in conjunction with containerization technologies such as Docker, but does not directly influence the MIG hardware partitioning.
