NVIDIA AI Operations - NCP-AIO Exam Practice Test

Question 1

An administrator is troubleshooting a bottleneck in a deep learning run time and needs consistent data feed rates to GPUs.
Which storage metric should be used?

A. Sequential read speed

B. Disk free space

C. Disk utilization in performance manager

D. Disk I/O operations per second (IOPS)

Correct Answer: A

Question 2

You are managing a deep learning workload on a Slurm cluster with multiple GPU nodes, but you notice that jobs requesting multiple GPUs are waiting for long periods even though there are available resources on some nodes.
How would you optimize job scheduling for multi-GPU workloads?

A. Increase time limits for smaller jobs so they don't interfere with multi-GPU job scheduling.

B. Set up separate partitions for single-GPU and multi-GPU jobs to avoid resource conflicts between them.

C. Reduce memory allocation per job so more jobs can run concurrently, freeing up resources faster for multi-GPU workloads.

D. Ensure that job scripts use --gres=gpu:<number> and configure Slurm's backfill scheduler to prioritize multi-GPU jobs efficiently.

Question 3

Which concept refers to the automated process of integrating code changes, testing them, and deploying machine learning models into production environments with minimal manual intervention?

A. Feature scaling

B. Data governance

C. CI/CD pipeline

D. Model pruning

Question 4

You have noticed that users can access all GPUs on a node even when they request only one GPU in their job script using --gres=gpu:1. This is causing resource contention and inefficient GPU usage.
What configuration change would you make to restrict users' access to only their allocated GPUs?

A. Increase the memory allocation per job to limit access to other resources on the node.

B. Set a higher priority for Jobs requesting fewer GPUs, so they finish faster and free up resources sooner.

C. Modify the job script to include additional resource requests for CPU cores alongside GPUs.

D. Enable cgroup enforcement in cgroup.conf by setting ConstrainDevices=yes.

Question 5

What steps should an administrator take if they encounter errors related to RDMA (Remote Direct Memory Access) when using Magnum IO?

A. Reboot all compute nodes after every job completion to reset RDMA settings automatically.

B. Disable RDMA entirely and rely on TCP/IP for all network communications between nodes.

C. Check that RDMA is properly enabled and configured on both storage and compute nodes for efficient data transfers.

D. Increase the number of network interfaces on each node to handle more traffic concurrently without using RDMA.

Question 6

A system administrator needs to optimize the delivery of their AI applications to the edge.
What NVIDIA platform should be used?

A. Base Command Platform

B. Base Command Manager

C. NetQ

D. Fleet Command

Question 7

You need to do maintenance on a node. What should you do first?

A. Set the node state to down in Slurm before completing maintenance.

B. Set the node state to down in Slurm before completing maintenance.

C. Disable job scheduling on all compute nodes in Slurm before completing maintenance.

D. Drain the compute node using scontrol update.

Question 8

You are managing a Slurm cluster with multiple GPU nodes, each equipped with different types of GPUs. Some jobs are being allocated GPUs that should be reserved for other purposes, such as display rendering.
How would you ensure that only the intended GPUs are allocated to jobs?

A. Use nvidia-smi to manually assign GPUs to each job before submission.

B. Increase the number of GPUs requested in the job script to avoid using unconfigured GPUs.

C. Verify that the GPUs are correctly listed in both gres.conf and slurm.conf, and ensure that unconfigured GPUs are excluded.

D. Reinstall the NVIDIA drivers to ensure proper GPU detection by Slurm.

Question 9

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. sbatch -begin=tomorrow

C. submit -begin=tomorrow

D. salloc -begin=tomorrow
