Topic
Details

Topic 1

Installation and Deployment: This section of the exam measures the skills of system administrators and addresses core practices for installing and deploying infrastructure. Candidates are tested on installing and configuring Base Command Manager, initializing Kubernetes on NVIDIA hosts, and deploying containers from NVIDIA NGC as well as cloud VMI containers. The section also covers understanding storage requirements in AI data centers and deploying DOCA services on DPU Arm processors, ensuring robust setup of AI-driven environments.

Topic 2

Troubleshooting and Optimization: NVIThis section of the exam measures the skills of AI infrastructure engineers and focuses on diagnosing and resolving technical issues that arise in advanced AI systems. Topics include troubleshooting Docker, the Fabric Manager service for NVIDIA NVlink and NVSwitch systems, Base Command Manager, and Magnum IO components. Candidates must also demonstrate the ability to identify and solve storage performance issues, ensuring optimized performance across AI workloads.

Topic 3

Workload Management: This section of the exam measures the skills of AI infrastructure engineers and focuses on managing workloads effectively in AI environments. It evaluates the ability to administer Kubernetes clusters, maintain workload efficiency, and apply system management tools to troubleshoot operational issues. Emphasis is placed on ensuring that workloads run smoothly across different environments in alignment with NVIDIA technologies.

Topic 4

Administration: This section of the exam measures the skills of system administrators and covers essential tasks in managing AI workloads within data centers. Candidates are expected to understand fleet command, Slurm cluster management, and overall data center architecture specific to AI environments. It also includes knowledge of Base Command Manager (BCM), cluster provisioning, Run.ai administration, and configuration of Multi-Instance GPU (MIG) for both AI and high-performance computing applications.

This format enables you to assess your NCP-AIO test preparation with a NVIDIA NCP-AIO certification exam. You can also customize your time and the kinds of NVIDIA NCP-AIO Exam Questions of the NVIDIA NCP-AIO practice test. PrepPDF has formulated NCP-AIO PDF questions for the convenience of NVIDIA NCP-AIO test takers.

NVIDIA AI Operations Sample Questions (Q60-Q65):

NEW QUESTION # 60
You are observing intermittent failures in your NVSHMEM application, and you suspect memory corruption. What is a good first step to debug this issue using NVSHMEM's debugging tools?

A. Increase the 'ulimit -r value
B. Enable NCCL DEBUG-INFO
C. Run the application with 'valgrind'
D. Set NVSHMEM DEBUG-MEMORY TRACE
E. Use 'cuda-memcheck'

Answer: D

Explanation:
Setting enables detailed memory allocation and deallocation tracing within NVSHMEM, which can help identify memory corruption issues. NCCL DEBUG is for NCCL issues, not NVSHMEM. Scuda-memcheck' is a good general tool for CUDA memory errors, but 'NVSHMEM_DEBUG' is more specific to NVSHMEM's managed memory. 'valgrind' is a general-purpose memory debugger, but NVSHMEM's built-in tracing is usually more effective for NVSHMEM-specific problems. The 'ulimit' value affects resource limits, but it doesn't directly help debug memory corruption.

NEW QUESTION # 61
You are tasked with deploying a multi-tenant AI cluster using Base Command Manager (BCM). How would you best isolate tenant workloads to ensure security and resource utilization?

A. Rely solely on user authentication and authorization for workload isolation.
B. Create separate physical clusters for each tenant.
C. Utilize Kubernetes namespaces and resource quotas within a single cluster.
D. Use Docker containers without resource limits, relying on the OS to manage resources.
E. Deploy individual VMS for each tenant's workloads, managed directly by BCM.

Answer: C

Explanation:
Kubernetes namespaces provide a logical separation of resources within a single cluster. Resource quotas limit the amount of resources that a namespace can consume, providing isolation and preventing one tenant from monopolizing resources. Creating separate clusters is costly. User authentication/authorization isn't sufficient alone for resource isolation.

NEW QUESTION # 62
You're managing a Slurm cluster used for deep learning training. Users report that their jobs are being killed unexpectedly. After investigation, you suspect the issue is related to exceeding memory limits. Which Slurm configuration parameter is MOST relevant to investigate and adjust to address this issue?

A. Prolog=/path/to/prolog_script
B. DefMemPerCPU
C. AccountingStorageType=accounting_storage/slurmdbd
D. Scheduler Type=sched/backfill
E. Oversubscribe-FORCE

Answer: B

Explanation:
DefMemPerCPU sets a default memory limit per CPU core. If users don't request enough memory and exceed this default, Slurm may kill their jobs. Investigating and adjusting this parameter is critical to preventing 00M (Out Of Memory) errors.

NEW QUESTION # 63
You are using GPUDirect Storage (GDS) to accelerate data loading directly from NVMe drives to GPU memory. After implementing GDS, you observe no performance improvement. What could be the reason?

A. GDS only supports single-GPU configurations.
B. The software libraries used for data loading (e.g., TensorFlow, PyTorch) are not GDS-aware.
C. The CUDA driver version is incompatible with the GDS version.
D. The system memory is a bottleneck and data is being staged to system memory before going to the GPU.
E. The NVMe drives are not directly attached to the GPUs via PCle.

Answer: B,C,D,E

Explanation:
GDS requires direct PCle connection between NVMe and GPU for optimal performance. The software libraries must be updated with a version that is GDS-aware to use this feature. Incompatible CUDA/GDS versions can cause failures. If the data has to go to system memory first before going to the GPU then you bypass GDS.

NEW QUESTION # 64
You have deployed the NVIDIA Device Plugin for Kubernetes on your BCM-managed cluster. After a kernel update on one of the worker nodes, the device plugin fails to discover the GPUs. The error messages indicate a mismatch between the driver version expected by the device plugin and the actual driver version installed on the node. What is the MOST reliable way to resolve this issue without disrupting other workloads?

A. Update the NVIDIA Device Plugin deployment manifest to specify the driver version installed on the node.
B. Use a DaemonSet to manage the NVIDIA driver installation on all worker nodes, ensuring a consistent driver version across the cluster and compatibility with the device plugin.
C. Manually downgrade the NVIDIA driver on the affected worker node to match the version expected by the device plugin.
D. Remove the NVIDIA Device Plugin and replace it with the 'nvidia-driver-installer' helm chart
E. Uninstall and reinstall the NVIDIA Container Toolkit on the affected worker node to automatically update the driver version.

Answer: B

Explanation:
Using a DaemonSet to manage the NVIDIA driver installation is the MOST reliable and scalable solution. It ensures that all worker nodes have the correct driver version and simplifies driver updates. Manually downgrading or updating individual nodes (A, B) is not sustainable. Reinstalling the toolkit (D) might not update the driver. Simply removing and replacing the plugin (E) doesn't address driver mismatch and would likely use a similar deployment method that would lead to the same error.
