NVIDIA AI Infrastructure NCP-AII Prüfungsfragen mit Lösungen (Q47-Q52):

47. Frage
A team is validating a DGX BasePOD deployment. Using cmsh, they run a command to check GPU health across all nodes. What indicates that the system is ready for AI workloads?

A. The command output is ignored if the system powers on without errors.
B. At least half of the GPUs report Status_Health = OK.
C. All GPUs report Status_Health = OK and Health = OK for each device.
D. Only the head node ' s GPUs need to be healthy.

Antwort: C

Begründung:
In an NVIDIA DGX BasePOD or SuperPOD environment, " Cluster Health " is a binary state: either the entire fabric and all compute resources are ready, or the cluster is considered degraded. Using the Bright Cluster Manager (BCM) shell (cmsh), administrators can aggregate telemetry from every node in the cluster.
For a system to be considered " Production Ready, " every single GPU across the multi-node deployment must report a status of Health = OK. This verification ensures that the hardware is communicating correctly over the PCIe bus, the NVLink fabric is initialized, and no ECC (Error Correction Code) memory errors are present. If even a single GPU in a 32-node cluster is unhealthy, collective communication libraries like NCCL may hang or experience significant performance penalties during " All-Reduce " operations, as the entire job typically scales to the speed of the slowest/unhealthiest component. Therefore, seeing Status_Health = OK for every device is the mandatory exit criterion for the bring-up phase.

48. Frage
A financial services firm is deploying an AI model for fraud detection that requires rapid inference and data retrieval across multiple sites. Which feature should their storage system prioritize?

A. Low-cost HDD solutions.
B. Tape backup systems.
C. High capacity with moderate speed.
D. Multi-protocol data access with low latency.

Antwort: D

Begründung:
The storage system should prioritize multi-protocol data access with low latency. Fraud detection workloads often depend on near-real-time inference, rapid lookup of transaction history, feature retrieval, and integration across multiple systems or sites. In an NVIDIA AI infrastructure environment, storage must support the AI workflow without starving GPUs, inference servers, or analytics pipelines. Multi-protocol access allows different applications and environments to access data through suitable interfaces, such as file or object protocols, while maintaining interoperability across on-premises and cloud-connected platforms. Low latency is essential because fraud decisions are time-sensitive; delayed data access can reduce model usefulness or prevent immediate action. Tape backup systems are useful for archival retention but are not suitable for live inference or fast analytics. Low-cost HDD-only storage may provide capacity but usually cannot meet latency and throughput requirements. High capacity with moderate speed is also insufficient when the business requirement is rapid retrieval across sites. For production AI operations, storage should be designed for responsiveness, availability, protocol compatibility, and consistent performance under concurrent workload demand.

49. Frage
After upgrading your NVIDIA drivers on a system with multiple GPUs, 'nvidia-smu reports 'No devices were found'. You've verified that the GPUs are physically connected correctly. What are the most likely causes and corresponding solutions?

A. The NVIDIA driver is incompatible with the installed CUDA toolkit. Solution: Downgrade or upgrade the CUDA toolkit to match the driver's compatibility requirements.
B. The X server is interfering with the driver. Solution: Stop the X server (e.g., 'sudo systemctl stop gdm3' or 'sudo systemctl stop lightdm') before running 'nvidia-smi'.
C. The user lacks necessary permissions. Solution: Add the user to the 'video' group.
D. The driver installation was interrupted or corrupted. Solution: Reinstall the driver, ensuring no errors during the process.
E. The NVIDIA kernel modules failed to load. Solution: Rebuild the kernel modules using DKMS and reboot.

Antwort: D,E

Begründung:
The most common causes are failure to load the kernel modules, often due to upgrade issues requiring a DKMS rebuild and reboot, or a corrupted installation requiring reinstallation. User permissions and CUDA toolkit version are less common in this scenario where no devices are found. While stopping the X server can sometimes help, it's not the primary solution if 'nvidia-smri' can't find the GPUs at all.

50. Frage
You are configuring an InfiniBand subnet with multiple switches. You need to ensure that traffic between two specific nodes always takes the shortest path, bypassing a potentially congested link. Which of the following approaches is MOST effective for achieving this using InfiniBand's routing capabilities?

A. Use static routing by manually configuring forwarding tables on each switch along the desired path. This involves specifying DLID-to-Port mappings.
B. Decrease the MTIJ size on the potential congested link.
C. Implement Quality of Service (QOS) to prioritize the traffic between the two nodes, hoping that this will influence the path selection.
D. Utilize the ibroute command or similar tool to inject a static route between the nodes, forcing traffic to follow a specific path identified by LID and port number.
E. Rely solely on the Subnet Manager's (SM) default path computation algorithm (e.g., Min Hop) without any modifications.

Antwort: D

Begründung:
Static routing with 'ibroute' (or similar) provides the most direct and reliable way to ensure traffic follows a specific path. The SM's default algorithm might not always choose the optimal path, and QOS only prioritizes traffic, not forces a specific route. Configuring forwarding tables manually on each switch is error-prone and difficult to manage at scale.

51. Frage
A DGX A100 server with dual power supplies reports a critical power event in the BMC logs. One PSU shows a 'degraded' status, while the other appears normal. What immediate actions should you take to ensure continued operation and prevent data loss?

A. Reduce the GPU power limit using 'nvidia-smi' to decrease the overall power consumption of the server.
B. Immediately shut down the server gracefully to prevent further damage to the faulty PSIJ.
C. Monitor the remaining PSU's load and temperature closely; if stable, continue operation until a scheduled maintenance window.
D. Migrate all workloads to other servers in the cluster to minimize the impact of a potential complete PSU failure.
E. Hot-swap the degraded PSU with a replacement unit.

Antwort: D,E

Begründung:
Hot-swapping the degraded PSU (B) restores redundancy. Migrating workloads (E) minimizes the risk of data loss or service interruption if the remaining PSU fails. Shutting down the server (A) causes unnecessary downtime if hot-swapping is possible. Monitoring the remaining PSU (C) is a good practice, but it's not a replacement for restoring redundancy or mitigating risk. Reducing GPU power limits (D) may help prevent further strain but is a temporary solution that impacts performance.
