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	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.

NVIDIA AI Operations Sample Questions (Q56-Q61):

NEW QUESTION # 56
A Slurm user needs to submit a batch job script for execution tomorrow.
Which command should be used to complete this task?

A. srun -begin=tomorrow
B. submit -begin=tomorrow
C. sbatch -begin=tomorrow
D. salloc -begin=tomorrow

Answer: C

Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
In Slurm cluster administration, the command to submit a batch job script is sbatch. This command schedules the job to be executed by the Slurm workload manager. The option -begin=tomorrow (or --begin=tomorrow) specifies the start time for the job execution, which in this case is set for tomorrow. The other commands have different purposes:
* submit is not a valid Slurm command.
* salloc is used to allocate resources interactively but does not submit batch jobs for scheduled execution.
* srun runs jobs immediately on allocated resources but is typically used to launch tasks in an active job or interactively, not for batch job submission.
Therefore, the correct command to submit a batch job script for future execution is sbatch -begin=tomorrow.

NEW QUESTION # 57
You are deploying a multi-GPU training job using a container from NGC on a Slurm cluster. The container expects the number of GPUs to be available in the 'CUDA VISIBLE DEVICES' environment variable. How do you ensure this variable is correctly set within the Slurm job script?

A. Use the Slurm command 'srun' with the '-gpus' option to allocate GPUs and automatically set
B. Utilize the Slurm environment variable 'SLURM JOB GPUS' to dynamically set 'CUDA_VISIBLE DEVICES' in the job script (e.g., 'export
C. Define the "CUDA VISIBLE DEVICES' environment variable in the containers Docket-file.
D. Configure the NVIDIA Container Toolkit to automatically detect and set 'CUDA VISIBLE DEVICES'.
E. Set the environment variable manually in the Slurm job script to a fixed value (e.g.,

Answer: A,B

Explanation:
B and D are correct. 'srun -gpus' handles GPU allocation and sets the environment variable. 'SLURM JOB GPUS provides a dynamic way to access allocated GPUs within the script. A is incorrect as it doesn't adapt to the actual allocation. C is incorrect because it's not a Slurm configuration. E depends on the specific toolkit version and might not be reliable without explicit configuration in the job script.

NEW QUESTION # 58
You are using an all-flash array (AFA) for your AI training dat
a. You observe that the storage utilization is very low, but you are still experiencing performance bottlenecks. What could be the potential reasons for this and how can you troubleshoot them?

A. The AFA's internal controllers are overloaded, even though the overall storage utilization is low. Monitor the controller utilization and consider upgrading the AFA or distributing the workload across multiple AFAs.
B. The AFA is over-provisioned, and the internal garbage collection processes are interfering with I/O operations. Reduce the amount of provisioned space.
C. The network connection between the compute nodes and the AFA is the bottleneck. IJpgrade the network infrastructure or optimize the data transfer protocols.
D. The AFA's warranty has expired. Renewing the warranty will magically fix the performance issues.
E. The AFA is not configured correctly to handle the specific I/O patterns of your AI workload (e.g., random reads, large sequential writes). Check the AFA's configuration settings for block size, caching policies, and prefetching.

Answer: A,C,E

Explanation:
IncorrectAFA configuration can lead to performance issues even with low utilization. Network bottlenecks can limit data transfer rates. Overloaded controllers within the AFA can become a bottleneck.

NEW QUESTION # 59
A user submits a Slurm job script with the following options:

Assuming each node has 4 GPUs, how many GPU resources will be allocated to this job across the entire cluster?

A. 0
B. 1
C. 2
D. 3
E. 4

Answer: D

Explanation:
The job requests 2 nodes (nodes=2) and one GPU per node Therefore, a total of 2 GPUs (2 nodes 1 GPU/node) will be allocated to the job.

NEW QUESTION # 60
A data scientist submits a Run.ai job requesting 4 GPUs. However, due to resource constraints, only 2 GPUs are immediately available. You want the job to automatically start running as soon as the remaining 2 GPUs become available, without manual intervention. How do you configure Run.ai to achieve this?

A. Set a higher quota for the team.
B. Enable gang scheduling for the job.
C. Use Run.ai's 'suspend' and 'resume' commands manually.
D. Configure a lower priority for the job.
E. Set the job's 'restartPolicy' to 'Always'.

Answer: B

Explanation:
Gang scheduling ensures that all requested resources (in this case, all 4 GPUs) are allocated before the job starts. The job will remain in a pending state until all resources are available, and then it will automatically start. 'restartPolicy only applies if a job fails after it has already started. Lower priority would make it less likely to start. Manually suspending and resuming requires intervention. A quota impacts how much you can submit overall, not the allocation of the complete resources requested by a single job.
