NEW QUESTION # 21
You have multiple users sharing a server with a single NVIDIAA100 GPU. Two users, Alice and Bob, want to run deep learning experiments concurrently. Alice's job requires 20GB of GPU memory and 30% of compute, while Bob's job needs IOGB of GPU memory and 20% of compute. How can you use MIG to optimally configure the GPU to accommodate both users' requirements?
- A. Do not use MIG; let both users share the entire GPU.
- B. Create two MIG instances: one 3g.20gb instance for Alice and one lg.5gb instance for Bob.
- C. Create two MIG instances: one 4g.20gb instance for Alice and one 2g.10gb instance for Bob.
- D. Create one MIG instance for Alice and let Bob use the remaining GPU resources.
- E. Create two MIG instances: one lg.5gb instance for Alice and one lg.5gb instance for Bob.
Answer: C
Explanation:
This question challenges understanding of MIG instance sizes. Options A and B are not correct because they allocate insufficient memory to Alice. Option C is not correct because it does not provide dedicated resources for Bob. Option E means that Alice's job is resource intensive. The correct answer is D because it ensures that both Alice and Bob get at least the memory they need and some compute resource allocation. 4g.20gb and 2g.10gb instances ensure allocation of resources required for both users independently.
NEW QUESTION # 22
What is the primary purpose of using a container runtime interface (CRI) with BCM and Kubernetes in an AI environment?
- A. To provide a standard interface for Kubernetes to interact with different container runtimes (e.g., Docker, containerd).
- B. To schedule pods onto nodes based on resource availability.
- C. To manage the lifecycle of containers (create, start, stop, delete).
- D. To encrypt container images at rest and in transit.
- E. To handle networking for containers within the Kubernetes cluster.
Answer: A
Explanation:
The CRI allows Kubernetes to work with various container runtimes without being tightly coupled to a specific implementation. It defines an interface that container runtimes must implement. While A is true for a container runtime, the CRI is about Kubernetes interacting with it. The others are related to other parts of Kubernetes.
NEW QUESTION # 23
You have a Run.ai cluster with multiple GPU nodes. You want to configure a specific job to ONLY run on nodes equipped with NVIDIA A100 GPUs. How can you achieve this node selection using Run.ai?
- A. Use Run.ai's built-in 'gpu-type' parameter in the job definition.
- B. Manually schedule the job on a specific AIOO node using the Run.ai CLI.
- C. Configure node affinity rules in the Run.ai job definition to target nodes with the 'nvidia.com/gpu.product' label equal to 'A1 00'.
- D. Specify the A100 GPU type in the Run.ai cluster configuration.
- E. Use Kubernetes taints and tolerations to restrict the job to A100 nodes.
Answer: C
Explanation:
Explanation:Using node affinity rules is the correct approach. By setting node affinity rules in the Run.ai job definition, you can target nodes based on labels, such as 'nvidia.com/gpu.product=A100'. Kubernetes taints and tolerations could also be used, but configuring node affinity within the Run.ai job definition provides a more streamlined approach. Run.ai doesn't have a built-in 'gpu-type' parameter for this specific purpose.
NEW QUESTION # 24

- C. Setting a higher 'nice' value for jobs submitted by other groups.
- D. Disabling preemption.
- E. Manually editing the Slurm job queue database.
Answer: C
Explanation:
Fairshare scheduling allows you to allocate resources based on a share value assigned to each user or group. By assigning a higher share value to the research group, their jobs will be prioritized for resource allocation.
NEW QUESTION # 27
You are experiencing inconsistent performance across different GPUs in your NVLink fabric. You suspect that some NVLink connections may be operating at a lower bandwidth than expected. How can you verify the actual bandwidth of each NVLink connection using ' nvsm' or related tools?
- A. Check the GPU temperature using 'nvidia-smi'.
- B. Monitor the network interface statistics using 'ifconfig' .
- C. Use 'nvsm show linkS and check the reported 'link speed'.
- D. Use 'nvsm show topology' and check the reported 'link width'.
- E. Run a benchmark tool like 'nvidia-smi nvlink -capcheck' to measure the achieved bandwidth.
Answer: E
Explanation:
While 'nvsm show linkS reports the configured link speed, it doesn't show the actual achieved bandwidth. A benchmark tool specifically designed for NVLink (similar to 'nvidia-smi nvlink -capcheck' , though the exact command might vary) is necessary to measure the actual bandwidth achieved on each connection. The other options provide unrelated information.
NEW QUESTION # 28

- A. DCGM Group Management
- B. DCGM Policy Management
- C. DCGM Health Checks
- D. DCGM Telemetry
- E. DCGM Profiler
Answer: B
Explanation:
DCGM Policy Management allows you to set thresholds and actions (such as alerts) based on GPIU metrics like temperature. Health Checks perform diagnostics, Telemetry provides monitoring data, Profiler analyzes performance, and Group Management organizes GPUs.
NEW QUESTION # 29
You are tasked with configuring MIG on an NVIDIAA100 GPU for a mixed AI/HPC workload. You need to create two instances: one for a deep learning training job (requiring high memory bandwidth) and another for a molecular dynamics simulation (requiring high compute throughput). Which is the MOST optimal MIG configuration to create based on these workload requirements?
- A. Two instances of lg.5gb. This ensures balanced resource allocation.
- B. One instance of 3g.20gb for deep learning and one instance of 4g.20gb for molecular dynamics simulation. This configuration dedicates larger memory and compute resources to each task based on the workload.
- C. One instance of 2g.10gb for deep learning and one instance of lg.5gb for molecular dynamics.
- D. Two instances of 7g.40gb. This provides maximum performance for both workloads.
- E. One instance of 4g.20gb for deep learning and one instance of 3g.20gb for molecular dynamics.
Answer: B
Explanation:
Deep learning training typically benefits from larger memory capacities and bandwidth. While molecular dynamics often leverages compute throughput. Therefore, allocating 3g.20gb for deep learning, with focus on memory, and 4g.20gb for molecular dynamics will better utilize computational resources based on the workload characteristics. The lg,2g options are too small, and 7g option might overcommit resources that other processes or users could need on the same node.
NEW QUESTION # 30
You are using the Run.ai CLI to monitor the status of a specific job with ID 'job-1 23'. The job is currently in a 'Pending' state. What command would you use to get detailed information about why the job is pending?
- A. runai debug job-123
- B. runai get events job-123
- C. runai describe job job-123
- D. runai logs job-123
- E. kubectl describe pod job-123
Answer: C
Explanation:
The 'runai describe job job-123' command provides detailed information about the job, including its status, resource requests, and any events or messages that explain why the job is in a pending state. 'runai get events would show events, but 'describe' gives a more comprehensive overview. 'runai logs would only show logs once the job starts running. 'runai debug' is for interactive debugging sessions. 'kubectl describe pod' might provide some information, but it's less integrated with Run.ai's scheduling and resource management features.
NEW QUESTION # 31
You are tasked with deploying a DOCA service on an NVIDIA BlueField DPU in an air-gapped data center environment. The DPU has the required BlueField OS version (3.9.0 or higher) installed, and you have access to the necessary container image from NVIDIA's NGC catalog. However, you need to ensure that the deployment process is successful without an internet connection.
Which of the following steps should you take to deploy the DOCA service on the DPU?
- A. Install Docker on the DPU, pull the container directly from NGC, and run it using 'docker run' with appropriate environment variables.
- B. Manually download the container image and YAML file beforehand, transfer them to the DPU, and deploy using Kubernetes with standalone Kubelet.
- C. Use the host system's Docker engine to pull the container image and deploy it on the DPU via SSH.
- D. Pull the container image from NGC using Docker and modify the YAML file before deployment.
Answer: B
Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
In an air-gapped environment where the DPU has no internet connectivity, direct pulling of container images from NVIDIA's NGC catalog is not possible. The recommended approach is tomanually download the required container image and YAML deployment filesfrom a connected system, then transfer these files to the DPU. Deployment is then performed using Kubernetes with a standalone Kubelet on the DPU, which can deploy the preloaded container image offline. This ensures the deployment proceeds successfully without internet access.
NEW QUESTION # 32
What is the primary benefit of using NVIDIA MIG in a multi-tenant environment?
- A. Increased network bandwidth.
- B. Decreased memory usage.
- C. Improved CPU performance.
- D. Simplified container deployment.
- E. Guaranteed isolation and resource allocation for each tenant.
Answer: E
Explanation:
MIG's primary benefit is to provide guaranteed isolation and resource allocation for each tenant in a multi-tenant environment. This ensures that each tenant has dedicated GPU resources and that their workloads do not interfere with each other.
NEW QUESTION # 33
How can you ensure that all newly provisioned nodes in your BCM cluster automatically have the necessary NVIDIA drivers and container runtime installed?
- A. Configure BCM to run a post-provisioning script that installs the drivers and runtime.
- B. Manually install the drivers and runtime on each node after provisioning.
- C. Create a custom OS image with the drivers and runtime pre-installed and use that image for provisioning.
- D. Rely on the NVIDIA automatic driver installation tool after the OS is booted.
- E. Use a Kubernetes DaemonSet to install the drivers and runtime on each node after it joins the cluster.
Answer: C,E
Explanation:
A custom OS image ensures drivers and runtime are present from the start. A post-provisioning script allows automated installation. Manual installation is not scalable. A DaemonSet installs software after the node joins the cluster, but BCM configuration happens at provisioning. The NVIDIA automatic driver installation tool might not be compatible with all BCM configurations.
NEW QUESTION # 34
You are tasked with deploying a multi-tenant AI cluster using Base Command Manager (BCM). How would you best isolate tenant workloads to ensure security and resource utilization?
- A. Deploy individual VMS for each tenant's workloads, managed directly by BCM.
- B. Rely solely on user authentication and authorization for workload isolation.
- C. Use Docker containers without resource limits, relying on the OS to manage resources.
- D. Utilize Kubernetes namespaces and resource quotas within a single cluster.
- E. Create separate physical clusters for each tenant.
Answer: D
Explanation:
Kubernetes namespaces provide a logical separation of resources within a single cluster. Resource quotas limit the amount of resources that a namespace can consume, providing isolation and preventing one tenant from monopolizing resources. Creating separate clusters is costly. User authentication/authorization isn't sufficient alone for resource isolation.
NEW QUESTION # 35
You are deploying a distributed AI training workload across multiple geographically separated data centers. Which network architecture would BEST minimize latency for inter-node communication?
- A. Public internet with standard TCP/IP routing.
- B. A dedicated private network with DWDM (Dense Wavelength Division Multiplexing) and optimized routing.
- C. A VPN (Virtual Private Network) over the public internet.
- D. A wireless mesh network.
- E. A content delivery network (CDN).
Answer: B
Explanation:
For geographically distributed training, minimizing latency is paramount. A dedicated private network with DWDM and optimized routing provides the lowest latency and most predictable performance compared to the public internet, VPNs, or CDNs. DWDM maximizes the bandwidth over fiber optic cables. A CDN is designed for content delivery, not low-latency communication between training nodes.
NEW QUESTION # 36
You are using BCM to manage a large cluster of GPU servers. You want to implement a mechanism to automatically scale the number of BCM instances based on the load. What Kubernetes feature would be MOST suitable for this purpose?
- A. Vertical Pod Autoscaler (VPA)
- B. Horizontal Pod Autoscaler (HPA)
- C. Node Auto-Provisioning
- D. Cluster Autoscaler
- E. kube-scheduler
Answer: B
Explanation:
The Horizontal Pod Autoscaler (HPA) is the most suitable Kubernetes feature for automatically scaling the number of BCM instances (pods) based on resource utilization (e.g., CPU, memory). HPA monitors the resource usage of the BCM pods and automatically adjusts the number of replicas to maintain the desired resource levels. VPA adjusts the resource requests and limits of individual pods. Cluster Autoscaler adds or removes nodes from the cluster. Node Auto-Provisioning is related to node management. Kube-scheduler schedules pods onto nodes.
NEW QUESTION # 37
You are the administrator of a Run.ai cluster with ACM enabled. You need to implement a chargeback mechanism to accurately track GPU usage and allocate costs to different research groups. What key pieces of information do you need to collect and what Run.ai and/or ACM features can help automate this process?
- A. GPU utilization per job, job duration, and associated research group. ACM and Run.ai provide APIs and dashboards for collecting this data, which can then be integrated with a billing system.
- B. Network bandwidth used by each job. This is the best indicator of resource consumption.
- C. CPU utilization per job. This is the primary factor in determining costs.
- D. Average job completion time. Use this to distribute the cost equally.
- E. Total number of jobs submitted by each group. Run.ai provides a summary of job submissions in the UI.
Answer: A
Explanation:
For accurate chargeback, you need GPU utilization per job, job duration (to quantify resource usage over time), and the associated research group to whom the cost should be allocated. ACM and Run.ai provide APIs and dashboards for collecting this data, which can be integrated with a billing system for automated chargeback. While the total number of jobs submitted can be an indicator of activity, it doesn't reflect actual resource usage. CPU utilization and network bandwidth are less relevant than GPU utilization in a GPU-accelerated environment. Average job completion time is insufficient for equitable cost allocation.
NEW QUESTION # 38
You are using 'nvsm' to manage your NVLink fabric. You want to verify the link speed and status between two specific GPUs. Which nvsm' command provides the MOST detailed information about individual NVLink connections?
- A. 'nvsm show topology'
- B. 'nvsm show health'
- C. 'nvsm show configuration'
- D. nvsm show devices'
- E. nvsm show links'
Answer: E
Explanation:
'nvsm show links' provides detailed information about the individual NVLink connections, including their speed, status, and error counts. 'nvsm show topology' provides a high-level overview, while the other commands focus on different aspects of the system.
NEW QUESTION # 39
You're troubleshooting a performance issue in a distributed training job running on your Slurm cluster. You suspect network bottlenecks are contributing to the problem. Which Slurm command and option(s) would be MOST helpful in diagnosing network performance issues within the job's allocated nodes?
- A. squeue -l
- B. scontrol show job
- C. srun -mpi=pmi2 iperf3 -s
- D. sstat -j
- E. sdiag
Answer: C
Explanation:
The 'srun -mpi=pmi2 iperf3 -S command, when executed within a Slurm job allocation, will launch an iperf3 server on each node allocated to the job, enabling you to measure network bandwidth between the nodes. This helps identify network bottlenecks.
NEW QUESTION # 40
Describe a scenario where using MIG (Multi-lnstance GPU) on an NVIDIAAI 00 GPU within a Kubernetes cluster would be most beneficial. Explain why MIG is advantageous in that specific use case.
- A. Distributing a single large training job across multiple GPUs on different nodes.
- B. Hosting a large number of small, independent AI inference services, each with modest GPU requirements.
- C. Executing a computationally intensive scientific simulation that benefits from high GPU memory bandwidth.
- D. Running a virtual desktop infrastructure (VDI) environment where each user requires dedicated GPU resources.
- E. Running a single, large deep learning training job that requires the full resources of the A100 GPU.
Answer: B,D
Explanation:
The correct answers are B and D. MIG is most advantageous when you have many smaller workloads that can each benefit from a dedicated, isolated GPU instance. For inference services (B), MIG allows you to efficiently pack multiple services onto a single A100. And also for VDI use-case (D) where each user expects to have assigned dedicated GPU resources for graphics rendering, video encoding, or other GPU accelerated operations for their VM. For option A, a single large training job needs the entire GPU's resources and wouldn't benefit from partitioning. Options C and E are more about compute power/scale than isolation and efficient resource sharing.
NEW QUESTION # 41
You need to configure BCM to send alerts when a GPU's temperature exceeds a critical threshold. Where would you configure this alerting policy within BCM?
- A. Within the DCGM configuration files on the GPU nodes.
- B. In the 'bcm_config.yaml' file.
- C. Through the BCM web interface, in the 'Alerting Policies' section.
- D. By creating a custom Prometheus rule and integrating it with BCM.
- E. Using the 'nvidia-smi' command-line tool to set temperature thresholds and trigger alerts.
Answer: C
Explanation:
BCM provides a dedicated 'Alerting Policies' section in its web interface where you can define rules and thresholds for various metrics, including GPU temperature. You can configure the specific threshold, the alert severity, and the notification channels (e.g., email, Slack). Other options are either not directly supported or are more complex and less integrated.
NEW QUESTION # 42
You are deploying AI applications at the edge and want to ensure they continue running even if one of the servers at an edge location fails.
How can you configure NVIDIA Fleet Command to achieve this?
- A. Configure Fleet Command's multi-instance GPU (MIG) to handle failover.
- B. Set up over-the-air updates to automatically restart failed applications.
- C. Enable high availability for edge clusters.
- D. Use Secure NFS support for data redundancy.
Answer: C
Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
To ensure continued operation of AI applications at the edge despite server failures, NVIDIA Fleet Command allows administrators toenable high availability (HA) for edge clusters. This HA configuration ensures redundancy and failover capabilities, so applications remain operational when an edge server goes down.
Over-the-air updates handle software patching but do not inherently provide failover. MIG manages GPU resource partitioning, not failover. Secure NFS supports storage redundancy but is not the primary solution for application failover.
NEW QUESTION # 43
You have configured MIG instances for different users in a multi-tenant environment. One user complains that their application is running slower than expected, despite having a dedicated MIG instance. You suspect resource contention on the host system. Which of the following could be causing the slowdown, even with MIG in place?
- A. Insufficient host memory. The overall host system might be running low on memory, causing swapping and slowing down all processes.
- B. Insufficient power provided by the PSU.
- C. MIG guarantees complete isolation, so resource contention is impossible.
- D. Network bandwidth limitations. If the application relies on network communication, bandwidth limitations could be the bottleneck.
- E. CPU core oversubscription. Even with dedicated MIG instances, CPU cores might be oversubscribed, leading to performance degradation.
Answer: A,D,E
Explanation:
MIG provides GPU resource isolation, but it does not isolate other system resources. CPU oversubscription, insufficient host memory, and network bandwidth limitations can all contribute to performance slowdowns, even with dedicated MIG instances. It's important to monitor and manage these resources in addition to GPU resources.
NEW QUESTION # 44
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 # 45
Which of the following statements regarding the NVIDIA Device Plugin for Kubernetes are correct?
- A. It ensures that containers have the necessary NVIDIA libraries and tools.
- B. It automatically installs the NVIDIA drivers on the nodes.
- C. It replaces the need for the NVIDIA Container Toolkit.
- D. It allows Kubernetes to be aware of the NVIDIA GPUs present on the nodes.
- E. It exposes GPUs as schedulable resources to Kubernetes.
Answer: D,E
Explanation:
The correct answers are A and C. The NVIDIA Device Plugin discovers NVIDIA GPUs on each node and advertises them as resources to the Kubernetes scheduler. It enables Kubernetes to allocate GPUs to containers. It does not install drivers (that's a separate process). It works with the NVIDIA Container Toolkit to provide the necessary libraries within the container. It does not replace the NVIDIA Container Toolkit; they work in conjunction.
