NVIDIA AI Operations Sample Questions (Q77-Q82):

NEW QUESTION # 77
You have a cluster dedicated to AI inference, serving models from a persistent volume. You're experiencing high latency and CPU usage on the nodes serving inference requests. You suspect that storage access patterns are contributing to the issue. Your persistent volume is backed by a distributed file system. Describe a strategy, including relevant tools and techniques, to analyze the storage I/O profile of your inference workloads and identify potential optimizations.

A. Use 'iotop' or 'iostat' on the compute nodes to monitor real-time I/O activity and identify processes with high disk I/O. Then check the related containers that are doing more of these reads/writes.
B. Capture network traffic using 'tcpdump' or Wireshark to analyze the communication patterns between the compute nodes and the storage system. Look for excessive network latency or congestion. Also monitor the network latency using tools like 'ping' or 'iperf.
C. Randomly restart the inference pods. If the issue goes away, it means the storage system was temporarily overloaded.
D. Utilize the distributed file system's monitoring tools (if available) to analyze I/O patterns at the file system level. This can reveal hotspots or inefficient data access patterns.
E. Implement storage QOS (Quality of Service) policies to prioritize inference workloads and limit the impact of other I/O-intensive processes.

Answer: A,B,D,E

Explanation:
'iotopTiostat' identifies I/O-heavy processes. 'tcpdump'/Wireshark/ping/iperf helps analyze network communication. File system monitoring tools reveal data access patterns. Implementing storage QOS prioritizes inference workloads. Only restart the inference pods if you have a strong reason, otherwise troubleshooting the storage using one of the other methods is best practice.

NEW QUESTION # 78
A data science team is experiencing frequent job failures in their Run.ai cluster due to exceeding GPU memory limits. You need to implement a solution that dynamically adjusts GPU resources based on the actual consumption of each job. Which Run.ai feature is MOST appropriate for this scenario?

A. Fractional GPUs (MIG)
B. Node Affinity
C. Dynamic Resource Allocation using GPU Metrics
D. Gang Scheduling
E. Guaranteed Quotas

Answer: C

Explanation:
Dynamic Resource Allocation, leveraging GPU metrics, is the most appropriate choice. It allows Rumai to monitor GPU utilization in real-time and adjust resources (primarily memory) allocated to jobs dynamically, preventing 00M errors and maximizing GPU utilization across the cluster. MIG partitioning statically divides GPUs, while quotas enforce limits but don't dynamically adjust. Gang scheduling is about scheduling entire groups of tasks together. Node affinity control where the jobs are scheduled and it does not help with memory allocation.

NEW QUESTION # 79
What is the primary role of the DOCA Comm Channel service in a DOCA application deployed on a DPU?

A. Offloading network packet processing to the DPU hardware for improved performance.
B. Providing a low-latency communication path for control messages and synchronization signals between the host and the DPU.
C. Facilitating high-bandwidth data transfer between the host and the DPU using RDM
D. Enabling direct memory access (DMA) between different memory regions within the DPU.
E. Monitoring the health and performance of the DPLJ and the DOCA application.

Answer: B

Explanation:
DOCA Comm Channel is designed for low-latency communication of control messages between the host and the DPU. It's not intended for high-bandwidth data transfers. RDMA is used for data transfers. DMA used to move data between memory spaces within DPU or between Host and DPU. Other option doesn't reflect doca comm channel role.

NEW QUESTION # 80
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. Set a higher priority for Jobs requesting fewer GPUs, so they finish faster and free up resources sooner.
B. Enable cgroup enforcement in cgroup.conf by setting ConstrainDevices=yes.
C. Modify the job script to include additional resource requests for CPU cores alongside GPUs.
D. Increase the memory allocation per job to limit access to other resources on the node.

Answer: B

Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
To restrict users' access strictly to the GPUs allocated to their jobs, Slurm usescgroups (control groups)for resource isolation. Enabling device cgroup enforcement by settingConstrainDevices=yesincgroup.
confenforces device access restrictions, ensuring jobs cannot access GPUs beyond those assigned.
* Increasing memory allocation or setting job priorities does not restrict device access.
* Modifying job scripts to request additional CPU cores does not limit GPU access.
Hence, enablingcgroup enforcement with ConstrainDevices=yesis the correct method to prevent users from accessing unallocated GPUs.

NEW QUESTION # 81
You are tasked with deploying NVIDIA Base Command Manager (BCM) on a Kubernetes cluster that utilizes NVIDIA GPUs for Ai workloads. The cluster already has the NVIDIA GPU Operator installed. Which of the following steps are crucial to ensure BCM can properly discover and manage the GPUs?

A. Deploy a separate monitoring solution like Prometheus to gather GPU metrics for BCM.
B. Verify that the 'nvidia-driver-daemonset' is running and properly mounting the NVIDIA drivers into the container pods.
C. Configure RBAC (Role-Based Access Control) to grant BCM the necessary permissions to access GPU metrics and manage resources within the Kubernetes namespace.
D. Install CUDA toolkit separately within the container image used by BCM.
E. Ensure the NVIDIA Device Plugin for Kubernetes is installed and correctly configured.

Answer: B,C,E

Explanation:
BCM relies on the NVIDIA Device Plugin to expose GPUs to Kubernetes. RBAC configuration is essential for BCM to interact with the cluster and manage GPU resources. The 'nvidia-driver-daemonset' ensures the necessary drivers are available within the pods where GPU workloads are executed. While a separate monitoring solution might provide additional insights, it's not strictly required for BCM's basic GPU discovery and management functionality. The CUDA toolkit is usually already present in the base images used for AI workloads.
