NVIDIA NCP-AIO Exam Syllabus Topics:

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

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 3

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 4

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.

NVIDIA AI Operations Sample Questions (Q34-Q39):

NEW QUESTION # 34
Which of the following are key considerations when selecting storage for an AI training workload using large datasets? (Select TWO)

A. Network bandwidth between storage and compute nodes.
B. Storage capacity.
C. CPU core count on the storage server.
D. IOPS (Input/Output Operations Per Second).
E. RAM on the storage server.

Answer: A,B,D

Explanation:
Capacity is obviously important for large datasets. IOPS and Network Bandwidth are critical for feeding data to the GPUs efficiently and avoiding bottlenecks during training. While CPU and RAM on storage servers are relevant, they are secondary to capacity, IOPS, and network performance. Insufficient bandwidth can lead to GPU starvation, significantly slowing down the training process.

NEW QUESTION # 35
An administrator is troubleshooting issues with an NVIDIA Unified Fabric Manager Enterprise (UFM) installation and notices that the UFM server is unable to communicate with InfiniBand switches.
What step should be taken to address the issue?

A. Reboot the UFM server to refresh network connections.
B. Verify the subnet manager configuration on the InfiniBand switches.
C. Install additional GPUs in the UFM server to boost connectivity.
D. Disable the firewall on the UFM server to allow communication.

Answer: B

Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
Communication issues between UFM server and InfiniBand switches often result from misconfigured or missingsubnet manager configurationon the switches. The subnet manager controls fabric membership and routing, so verifying and correcting its setup is essential for proper UFM operation. Rebooting, adding GPUs, or disabling firewalls are less likely to resolve fabric-level communication problems.

NEW QUESTION # 36
You are managing a cluster with multiple nodes connected via NVLink and NVSwitch. After a network outage, some of the NVLink connections are showing as 'degraded' in 'nvsm show links'. What steps should you take to attempt to restore the connections to their optimal state? (Select TWO correct answers)

A. Restart the 'nvsm' service on all nodes.
B. Run 'nvsm repair linkS on the affected nodes.
C. Update the BIOS on all servers.
D. Reboot all nodes in the cluster simultaneously.
E. Check physical NVLink cable connections for damage or looseness.

Answer: A,E

Explanation:
Restarting the 'nvsm' service can help re-establish the connections. Checking the physical cable connections is crucial to ensure they are secure and undamaged. 'nvsm repair links' is not a valid command. Rebooting the entire cluster may be necessary in some situations, but it's a more disruptive step to take initially. A BIOS update is unlikely to solve the problem if it arose after a network outage.

NEW QUESTION # 37
You're troubleshooting a slow BCM-based AI workload. GPU utilization is low, and 'nvidia-smi' shows idle GPUs. You suspect a bottleneck in data transfer. Which of the following is the MOST likely cause?

A. Network latency between the storage system and the BCM pipeline.
B. All of the above.
C. Incorrect BCM configuration leading to inefficient data pipelining.
D. GPU driver version incompatibility with the BCM framework.
E. Insufficient CPU cores allocated to data preprocessing.

Answer: B

Explanation:
All options contribute to potential bottlenecks in BCM pipelines. Insufficient CPU cores hamper preprocessing. Incorrect BCM configuration ruins pipelining. Driver incompatibilities cause performance hits or failures. Network latency delays data ingestion.

NEW QUESTION # 38
You have a Slurm cluster configured with multiple partitions, and you want to restrict a specific user group to only submit jobs to a particular partition. How can you achieve this using Slurm's Quality of Service (QOS) and Access Control features?

A. Use the 'scontror command to set the default partition for the user group.
B. Create a QOS that allows access only to the desired partition and assign that QOS to the user group using 'sacctmgr' .
C. Configure PAM (Pluggable Authentication Modules) to restrict user access based on group membership.
D. Modify the partition configuration to include the user group in the 'AllowGroupS parameter.
E. Edit the user's .bashrc file to include #SBATCH --partition=.

Answer: B

Explanation:
Creating a QOS that restricts access to the desired partition and associating that QOS with the user group is the most direct and controlled method. The 'sacctmgr' tool is used to manage QOS and user/group associations.
