NVIDIA NCP-AIO Exam Syllabus Topics:

TopicDetails
Topic 1
  • 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 2
  • 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.
Topic 3
  • 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 4
  • 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.

NVIDIA AI Operations Sample Questions (Q86-Q91):

NEW QUESTION # 86
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?

Answer: D

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.


NEW QUESTION # 87
You are using BCM to provision a multi-node Kubernetes cluster on NVIDIA DGX servers. One of the nodes consistently fails to join the cluster. You've verified network connectivity and DNS resolution. The 'kubelet' logs show errors related to certificate signing. Which of the following steps is MOST likely to resolve this issue?

Answer: C

Explanation:
When a node fails to join the cluster due to certificate signing issues, it typically means the kubelet has requested a certificate from the Kubernetes API server, but that request has not been approved. Approving the pending CSR using 'kubectl certificate approve' is the standard way to resolve this issue. A (Regenerating the token is less likely since the token may still be valid), C (Manual copy is not scalable), D (disabling TLS is insecure), and E (kube-proxy is not related to cert signing process).


NEW QUESTION # 88
You have a Kubernetes cluster with several nodes equipped with NVIDIA GPUs. You want to ensure that pods requesting GPUs are only scheduled on nodes that have the appropriate NVIDIA drivers and the NVIDIA Container Toolkit installed. Which Kubernetes feature(s) can you leverage to achieve this?

Answer: D,E

Explanation:
The correct answers are A and E. Taints and Tolerations ensure that pods are not scheduled onto inappropriate nodes. Nodes can be tainted to indicate the lack of NVIDIA drivers or the Container Toolkit, and pods requiring GPUs can tolerate these taints to indicate their compatibility. Node Affinity, in tandem with taints, provides more fine-grained control over scheduling. You can use node affinity to prefer or require that pods with GPU requests are scheduled on nodes labeled with specific NVIDIA hardware or driver versions. Options B, C, and D are not directly relevant to GPU-aware scheduling.


NEW QUESTION # 89
You are attempting to run a Docker container that leverages NVIDIA GPUs, but encounter the following error: 'docker: Error response from daemon: could not select device driver "nvidia" with capabilities: [[gpu]].' What is the most probable cause and how would you resolve it?

Answer: D,E

Explanation:
The error message 'could not select device driver nvidia with capabilities: [[gpu]]' points directly to a problem with the NVIDIA Container Toolkit (A), and incorrect NVIDIA runtime setup and configuration within the Docker daemon. Verify installation of NVIDIA Container Toolkit, and set the default runtime in 'letc/docker/daemon.json' file.


NEW QUESTION # 90
The 'nvsm' service is consistently crashing on one of your nodes. Analyzing the core dump reveals a segmentation fault related to memory access within the NVSwitch driver. What is the MOST appropriate course of action?

Answer: E

Explanation:
Segmentation faults related to driver code usually indicate a bug within the driver itself. Reporting the issue with a core dump allows NVIDIA engineers to investigate and provide a fix. Trying to debug the driver yourself (recompiling) or disabling the NVSwitch are less effective solutions for this type of problem. Different versions of CUDA also can cause problems, but first report with the core dump.
