NEW QUESTION # 154
You need to configure persistent network settings on your BlueField SmartNIC after deploying BlueField OS. Which file should you modify to ensure these settings are applied after each reboot, assuming a Debian-based distribution?

• A. /etc/resolv.conf
• B. /etc/hostname
• C. /etc/sysconfig/network-scripts/ifcfg-
• D. /etc/network/interfaces
• E. /etc/dhcp/dhclient.conf

Answer: D

Explanation:
On Debian-based systems, the '/etc/network/interfaces' file is the standard location for configuring persistent network settings. Changes made to this file will be applied on each boot. Vetc/resolv.conf is for DNS settings, &/etc/hostname' sets the system's hostname, and '/etc/sysconfig/network-scripts/ifcfg-' is more commonly found on Red Hat-based systems. letc/dhcp/dhclient.conf is for DHCP settings.

NEW QUESTION # 155
Consider the following simplified CUDA code snippet intended to perform a vector addition:
What are critical steps to validate that this code is correctly utilizing the GPU hardware and producing accurate results?

• A. Run the code with 'cuda-memchecK to detect memory access errors or race conditions.
• B. Use 'cudaDeviceSynchronize()' after launching the kernel to ensure the GPU computations are complete before copying data back to the host.
• C. Ensure that 'blocksPerGrid' and 'threadsPerBlock' are appropriately chosen to maximize GPU occupancy, potentially using the NVIDIA CUDA Occupancy Calculator.
• D. After the 'cudaMemcpy' from device to host, compare the 'c' array to a CPU-based vector addition result to verify correctness.
• E. All of the above

Answer: E

Explanation:
All options highlight important validation steps. Optimizing block/thread configuration maximizes GPU utilization. Verifying results against a CPU-based calculation ensures correctness. 'cudaDeviceSynchronize()' guarantees GPU computations are finished before data transfer. 'cuda-memcheck' detects memory errors. Failing to do any of these could lead to subtle errors or performance bottlenecks.

NEW QUESTION # 156
You are running a distributed training job across multiple nodes, using a shared file system for storing training dat a. You observe that some nodes are consistently slower than others in reading data. Which of the following could be contributing factors to this performance discrepancy? Select all that apply.

• A. Insufficient RAM on the slower nodes for caching data.
• B. Uneven data distribution across the storage nodes.
• C. Different CPU architectures on the nodes.
• D. Network congestion between the slower nodes and the storage system.
• E. Variations in the speed of the local temporary storage (e.g., /tmp) used for intermediate files.

Answer: A,B,D

Explanation:
Network congestion (A) can directly impact the data transfer rate between the slower nodes and the storage. IJneven data distribution (B) means some storage nodes are more heavily loaded, leading to slower response times for nodes accessing data on those overloaded nodes. Insufficient RAM (D) limits the amount of data that can be cached locally, forcing more frequent reads from the slower storage system. CPU architecture (C) primarily affects compute performance, not 1/0. The speed of /tmp (E) is relevant if the training job uses local storage extensively for temporary files, but the question focuses on reading training data from the shared file system.

NEW QUESTION # 157
You are installing four NVIDIAAIOO GPUs in a server, and after installation, you observe that the PCle link speed for one of the GPUs is running at x8 instead of the expected x16. What could be the POSSIBLE causes for this reduced PCle link speed?

• A. The PCle slot is only wired for x8 speed.
• B. The GPU is faulty.
• C. The BIOS/UEFI is configured to limit the PCle link speed for that slot.
• D. The CPU does not have enough PCle lanes to support all GPUs at x16.
• E. All of the above

Answer: E

Explanation:
A reduced PCle link speed can result from multiple factors: a faulty GPU, insufficient PCle lanes from the CPU, the physical wiring of the PCle slot, or a BIOS/IJEFI configuration limiting the speed. All these are potentially viable cause. Thus answer E is correct.

NEW QUESTION # 158
A DGX A100 server with dual power supplies reports a critical power event in the BMC logs. One PSU shows a 'degraded' status, while the other appears normal. What immediate actions should you take to ensure continued operation and prevent data loss?

• A. Migrate all workloads to other servers in the cluster to minimize the impact of a potential complete PSU failure.
• B. Hot-swap the degraded PSU with a replacement unit.
• C. Immediately shut down the server gracefully to prevent further damage to the faulty PSIJ.
• D. Monitor the remaining PSU's load and temperature closely; if stable, continue operation until a scheduled maintenance window.
• E. Reduce the GPU power limit using 'nvidia-smi' to decrease the overall power consumption of the server.

Answer: A,B

Explanation:
Hot-swapping the degraded PSU (B) restores redundancy. Migrating workloads (E) minimizes the risk of data loss or service interruption if the remaining PSU fails. Shutting down the server (A) causes unnecessary downtime if hot-swapping is possible. Monitoring the remaining PSU (C) is a good practice, but it's not a replacement for restoring redundancy or mitigating risk. Reducing GPU power limits (D) may help prevent further strain but is a temporary solution that impacts performance.

NEW QUESTION # 159
You've deployed a GPU-accelerated application in Kubernetes using the NVIDIA device plugin. However, your pods are failing to start with an error indicating that they cannot find the NVIDIA libraries. Which of the following could be potential causes of this issue? (Multiple Answers)

• A. The NVIDIA device plugin is not properly configured in the Kubernetes cluster.
• B. The 'nvidia-container-runtime' is not configured as the default runtime for Docker/containerd.
• C. The NVIDIA drivers are not installed on the host node.
• D. The application container image does not include the necessary NVIDIA libraries.
• E. The GPU's compute capability is not sufficient for the workload.

Answer: A,B,C,D

Explanation:
If pods cannot find NVIDIA libraries, it could be because the drivers are missing on the host, the container runtime is not configured to use the NVIDIA runtime, the NVIDIA device plugin is misconfigured preventing GPU discovery and allocation, or the application container image does not include the NVIDIA libraries. E is likely incorrect, if the GPU's compute capability is insufficient then the app would likely start, but throw an error when trying to use the GPU.

NEW QUESTION # 160
You're profiling the performance of a PyTorch model running on an AMD server with multiple NVIDIA GPUs. You notice significant overhead in the data loading pipeline. Which of the following strategies can help optimize data loading and improve GPU utilization?
Select all that apply.

• A. Implementing asynchronous data prefetching using 'torch .Generator'.
• B. Reducing the batch size to decrease the amount of data loaded per iteration.
• C. IJsing a faster storage system (e.g., NVMe SSD instead of HDD).
• D. Using the 'torch.utils.data.DataLoader' with multiple worker processes.
• E. Loading the entire dataset into RAM before training.

Answer: A,C,D

Explanation:
Using multiple worker processes in 'DataLoader' enables parallel data loading. Asynchronous prefetching allows data to be loaded while the GPU is processing the current batch. A faster storage system reduces the 1/0 bottleneck. Loading the entire dataset into RAM might not be feasible for large datasets. Reducing batch size reduces the amount of data loaded but could decrease overall GPU utilizatiom

NEW QUESTION # 161
You're deploying a new cluster with multiple NVIDIAAIOO GPUs per node. You want to ensure optimal inter-GPU communication performance using NVLink. Which of the following configurations are critical for achieving maximum NVLink bandwidth?

• A. The server must use a specific CPU model to leverage NVLink capabilities.
• B. The motherboard must support PCle Gen5 to maximize NVLink bandwidth.
• C. GPUs should be physically installed in slots that maximize direct NVLink connections based on the server's architecture.
• D. The NVIDIA driver must be configured to enable NVLink; it is disabled by default.
• E. All GPUs within a node must be the same model and have identical firmware versions.

Answer: C,E

Explanation:
For optimal NVLink performance, several conditions must be met. GPUs of the same model and firmware ensure compatibility and prevent performance bottlenecks. Physical placement is critical; GPUs must be installed in slots that maximize direct NVLink connections, as defined by the server's architecture and documentation. While PCle Gen5 is beneficial for overall system performance, it does not directly impact NVLink bandwidth. NVLink is typically enabled by default. Some CPU models may be preferable, but it's the motherboard's NVLink topology that is more important.

NEW QUESTION # 162
You are using a custom container runtime other than Docker (e.g., containerd) and need to integrate it with the NVIDIA Container Toolkit.
What command would you use to configure the NVIDIA Container Toolkit for this runtime? (Assume your runtime configuration file is located at '/etc/containerd/config.toml')

• A. 'nvidia-docker runtime configure -runtime=containerd'
• B. nvidia-ctk runtime configure -runtime=custom -config=/etc/containerd/config.tomr
• C. nvidia-ctk runtime install -runtime-containerd'
• D. nvidia-ctk runtime config -runtime=containerd -set-default'
• E. nvidia-ctk runtime configure

Answer: B

Explanation:
The Anvidia-ctk runtime configure' command is used to configure the NVIDIA Container Toolkit for different container runtimes. When the runtime is not a standard one, the '-runtime=custom' option must be used, and you also provide the path to the configuration file using config=/etc/containerd/config.tomr. There is no 'install' or 'config' subcommand under 'nvidia-ctk runtime' for runtime selection.

NEW QUESTION # 163
After upgrading your NVIDIA drivers on a system with multiple GPUs, 'nvidia-smu reports 'No devices were found'. You've verified that the GPUs are physically connected correctly. What are the most likely causes and corresponding solutions?

• A. The NVIDIA driver is incompatible with the installed CUDA toolkit. Solution: Downgrade or upgrade the CUDA toolkit to match the driver's compatibility requirements.
• B. The X server is interfering with the driver. Solution: Stop the X server (e.g., 'sudo systemctl stop gdm3' or 'sudo systemctl stop lightdm') before running 'nvidia-smi'.
• C. The driver installation was interrupted or corrupted. Solution: Reinstall the driver, ensuring no errors during the process.
• D. The NVIDIA kernel modules failed to load. Solution: Rebuild the kernel modules using DKMS and reboot.
• E. The user lacks necessary permissions. Solution: Add the user to the 'video' group.

Answer: C,D

Explanation:
The most common causes are failure to load the kernel modules, often due to upgrade issues requiring a DKMS rebuild and reboot, or a corrupted installation requiring reinstallation. User permissions and CUDA toolkit version are less common in this scenario where no devices are found. While stopping the X server can sometimes help, it's not the primary solution if 'nvidia-smri' can't find the GPUs at all.

NEW QUESTION # 164
A GPU in your AI server consistently overheats during inference workloads. You've ruled out inadequate cooling and software bugs.
Running 'nvidia-smi' shows high power draw even when idle. Which of the following hardware issues are the most likely causes?

• A. Degraded thermal paste between the GPU die and the heatsink.
• B. Incorrectly seated GPU in the PCle slot, leading to poor power delivery.
• C. A failing voltage regulator module (VRM) on the GPU board, causing excessive power leakage.
• D. A BIOS setting that is overvolting the GPU.
• E. Insufficient system RAM.

Answer: A,B,C

Explanation:
Degraded thermal paste loses its ability to conduct heat effectively. A failing VRM can cause excessive power draw and heat generation. An incorrectly seated GPU can cause instability and poor power delivery, leading to overheating. Overvolting in BIOS will definitely cause overheating. While insufficient RAM can cause performance issues, it is less likely to lead to overheating.

NEW QUESTION # 165
You've flashed the BlueField OS to your SmartNlC, but you need to customize the kernel command line arguments (bootargs) to enable a specific feature. Where is the MOST appropriate place to modify these arguments for persistent changes that survive reboots?

• A. Passing it as an argument to bfboot during deployment.
• B. Directly in the kernel image file itself using a hex editor.
• C. In the bootloader configuration file (e.g., extlinux.conf or grub.cfg) on the BlueFieId's flash memory.
• D. In the '/proc/cmdline' file. This allows immediate changes.
• E. In the '/etc/default/grub' file on the BlueField OS, followed by updating the GRUB configuration.

Answer: C

Explanation:
The bootloader configuration file (extlinux.conf, grub.cfg, uEnv.txt depending on the system) is where boot arguments are persistently stored. Modifying the kernel image directly is highly discouraged and risky. 'letc/default/grub' is a common location on standard Linux systems, but not necessarily on the BlueField OS's boot environment. '/proc/cmdline' shows the currently used arguments, but modifying it doesn't persist changes across reboots. bfboot will only change the image during that flash, changes at the bootloader level persist after subsequent flashes.

NEW QUESTION # 166
You are building a Docker image for a deep learning application that requires an NVIDIA GPU. Which of the following instructions is the most efficient way to ensure the NVIDIA drivers are available within the container, assuming you are using the nvidia/cuda/' base image and want to minimize the image size?

• A. RUN apt-get update && apt-get install -y nvidia-driver-470
• B. Using 'nvidia/cuda' base image, the drivers are already included, so no further action is needed.
• C. FROM nvidia/cuda:ll .4.2-base-ubuntu20.04 RUN apt-get update && apt-get install -y -no-install-recommends nvidia-driver-470
• D. COPY /usr/lib/nvidia /usr/local/nvidia/
• E. FROM nvidia/cuda:ll .4.2-base-ubuntu20.04 AS builder RUN apt-get update && apt-get install -y -no-install-recommends software-properties-common RUN add-apt-repository ppa:graphics-drivers/ppa RUN apt-get update && apt-get install -y -no-install-recommends nvidia-driver-470 FROM ubuntu:20.04 COPY -from=builder /usr/lib/nvidia /usr/lib/ COPY -from=builder /usr/local/nvidia /usr/local/

Answer: B

Explanation:
The Anvidia/cuda' base images provided by NVIDIA come pre-installed with the necessary NVIDIA drivers and CUDA toolkit. Therefore, you don't need to manually install or copy driver files. This is the most efficient method as it avoids unnecessary bloat in the Docker image. Options A, B, C and D all lead to redundant driver installations, increasing image size.

NEW QUESTION # 167
You are troubleshooting a performance issue with NVMe-oF traffic being accelerated by a BlueField-2 DPU. You suspect a problem with the RDMA configuration. Which of the following 'perfquery" commands would provide the MOST relevant information to diagnose potential RDMA issues such as packet loss or congestion?

• A. 'perfquery -x' (general link statistics)
• B. 'perfquery -G' (global counters)
• C. 'perfquery (QOS statistics)
• D. 'perfquery -s;' (switch statistics)
• E. 'perfquery -P (port counters including packet loss and congestion)

Answer: E

Explanation:
'perfquery -P' provides port counters, including critical information about packet loss, congestion, and other RDMA-related metrics atthe port level. This is the MOST relevant command for diagnosing performance problems related to RDMA within an NVMe-oF setup. Other options provide less specific or relevant information.

NEW QUESTION # 168
You are setting up a multi-GPU AI server for deep learning. You want to ensure optimal inter-GPU communication. Which of the following interconnect technologies would provide the BEST performance?

• A. Infiniband
• B. PCle Gen4 x16
• C. NVLink
• D. PCle Gen3 x16
• E. Ethernet

Answer: C

Explanation:
NVLink is designed specifically for high-bandwidth, low-latency inter-GPU communication, offering significantly better performance than PCIe or network connections for workloads that benefit from it. InfiniBand is suitable for node to node communication, while NVLink is for GPU to GPU on the same node.

NEW QUESTION # 169
You are replacing a faulty NVIDIA Tesla V 100 GPU in a server. After physically installing the new GPU, the system fails to recognize it. You've verified the power connections and seating of the card. Which of the following steps should you take next to troubleshoot the issue?

• A. Reinstall the operating system to ensure proper driver installation.
• B. Update the system BIOS and BMC firmware to the latest versions.
• C. Check if the new GPU requires a different driver version than the currently installed one and update if needed.
• D. Immediately RMA the new GPU as it is likely defective.
• E. Disable and re-enable the GPU slot in the system BIOS.

Answer: B,C

Explanation:
After verifying the physical installation, the next steps are to ensure the system's firmware is up-to-date and that the correct drivers are installed. Older BIOS/BMC firmware may not properly recognize newer GPUs, and incorrect drivers will prevent the GPU from functioning correctly. RMAing the new GPU or reinstalling the OS prematurely are inefficient troubleshooting steps. The system BIOS may have an option to disable and enable the GPU slot, but that would be rare.

NEW QUESTION # 170
You are deploying a multi-node A1 training cluster using Kubernetes, with each node equipped with multiple NVIDIA GPUs. You want to ensure that the Kubernetes scheduler is aware of the GPU resources available on each node and can efficiently allocate GPU-enabled pods to the appropriate nodes. Besides installing the NVIDIA Container Toolkit, what other components are essential for enabling GPU-aware scheduling in Kubernetes?

• A. The NVIDIA GPU Operator.
• B. The NVIDIA Fabric Manager
• C. The Kubernetes Horizontal Pod Autoscaler (HPA).
• D. The NVIDIA Device Plugin for Kubernetes.
• E. The Kubernetes Resource Quota controller.

Answer: A,D

Explanation:
The NVIDIA Device Plugin for Kubernetes (A) is essential for advertising the GPU resources to the Kubernetes scheduler. It allows Kubernetes to understand that GPUs are available and track their usage. The NVIDIA GPU Operator (C) simplifies the deployment and management of NVIDIA drivers and other components required for GPU support in Kubernetes, including the device plugin. The Resource Quota controller (B) is useful for limiting resource consumption but doesn't directly enable GPU-aware scheduling. HPA (D) is used for autoscaling based on CPU or memory utilization, not GPU utilization. Fabric Manager is for managing GPU interconnect and not related.

NEW QUESTION # 171
You have created MIG instances on an A100 GPU and want to dynamically adjust their size based on workload demands. Which of the following methods is the most appropriate for automatically resizing MIG instances in response to changing resource requirements?

• A. Utilize CUDA MPS to dynamically allocate GPU resources to different processes.
• B. Use 'nvidia-smi' to manually destroy and recreate MIG instances with different sizes as needed.
• C. Adjust the application code to use less GPIJ memory dynamically.
• D. Implement a script that monitors GPU utilization and automatically adjusts Kubernetes resource quotas to match.
• E. Leverage a GPU virtualization platform with dynamic resource allocation capabilities that integrates with MIG.

Answer: E

Explanation:
Explanation: Dynamically resizing MIG instances requires a mechanism that can automatically adjust the underlying GPU partitioning based on workload demands. The most appropriate method is leveraging a GPU virtualization platform (C) that offers dynamic resource allocation and integrates with MIG. These platforms can monitor resource utilization and automatically resize MIG instances accordingly. Manually resizing (A) is impractical for dynamic adjustments. Kubernetes resource quotas (B) control container resource limits, not the underlying MIG configuration. CUDA MPS (D) allows sharing a single GPU but doesn't resize MIG instances. Adjusting application code (E) doesn't address the need for dynamic MIG resizing.

NEW QUESTION # 172
You are setting up a multi-node A1 cluster with NVIDIA GPUs and InfiniBand for inter-node communication. You need to ensure the InfiniBand network is functioning optimally for GPU-accelerated workloads. What steps would you take to validate the InfiniBand installation and performance?

• A. Verify the InfiniBand drivers are installed and then run a standard TCP benchmark between the nodes.
• B. Run 'ibstat' to check InfiniBand interface status, use 'ibping' and 'ibperf to test latency and bandwidth, and verify correct NCCL configuration (e.g., during a distributed training run.
• C. Run 'ibstat' to check InfiniBand interface status, use 'ping' to test connectivity, and rely on NCCL's internal checks during training.
• D. Configure a static IP address on the InfiniBand interfaces, and rely on the operating system's network diagnostics.
• E. Use 'nvidia-smi' to monitor InfiniBand traffic, and rely on CUDA-aware MPl for communication validation.

Answer: B

Explanation:
Sibstat' verifies interface status. 'ibping' and 'ibperf are InfiniBand-specific tools for latency and bandwidth testing. NCCL (NVIDIA Collective Communications Library) is critical for distributed training, and provides valuable diagnostic information. The other options are either incomplete or rely on tools not specific to InfiniBand.

NEW QUESTION # 173
You are deploying a cloud-native AI inference service using Kubernetes and NVIDIA GPUs. You need to ensure that GPU resources are efficiently allocated and monitored. Which of the following approaches is MOST effective for achieving this within the Kubernetes environment?

• A. Overcommitting GPU resources and relying on the Kubernetes scheduler to handle potential out-of-memory (OOM) errors.
• B. Manually assigning specific GPU devices to pods using hostPath volumes and environment variables.
• C. Deploying a dedicated monitoring agent on each node to track GPU utilization and manually adjusting pod resource requests based on these metrics.
• D. Using the NVIDIA Device Plugin for Kubernetes to advertise GPU resources and utilizing resource requests and limits to schedule pods on nodes with available GPUs.
• E. Relying solely on Kubernetes' default CPU and memory resource requests and limits, assuming GPU usage will be implicitly managed.

Answer: D

Explanation:
The NVIDIA Device Plugin for Kubernetes is specifically designed to advertise GPU resources to the Kubernetes scheduler, enabling efficient allocation and utilization. Resource requests and limits ensure pods are scheduled on nodes with sufficient GPU capacity, preventing resource contention and 00M errors. Options A, C, D, and E are either ineffective, manual, or potentially lead to instability.

NEW QUESTION # 174
An AI infrastructure uses a combination of air-cooled and liquid-cooled NVIDIA GPUs. You want to optimize cooling performance based on the specific thermal characteristics of each GPU type and their location within the server rack. How can you achieve granular cooling control and monitoring to address these heterogeneous cooling requirements effectively? SELECT TWO.

• A. Implement rack-level airflow management solutions, such as blanking panels and cable management, to improve overall airflow uniformity.
• B. Use a centralized monitoring system to track GPU temperatures and power consumption, but apply the same cooling profile to all GPUs regardless of type.
• C. Implement dynamic fan speed control based on individual GPU temperatures, leveraging tools like 'nvidia-smi' and custom scripts, for air-cooled GPUs.
• D. Deploy per-server cooling solutions with independent fan control for each server node, allowing for tailored airflow adjustments.
• E. Employ liquid cooling only for the highest TDP GPUs and rely on ambient air cooling for all other components.

Answer: A,C

Explanation:
Implementing rack-level airflow management (A) improves overall airflow uniformity, which benefits all GPUs, regardless of cooling type. Implementing dynamic fan speed control based on individual GPU temperatures for air-cooled GPUs (E) allows for fine-grained adjustments to cooling performance. Per-server cooling solutions (C) can be helpful, but less scalable/practical in most datacenters. Using the same cooling profile for all GPUs (B) is ineffective. Cooling only high TDP GPUs (D) may not be sufficient.

NEW QUESTION # 175
After deploying BlueField OS, you notice that the network interfaces are not automatically configured with IP addresses. Which of the following actions would be the MOST appropriate first step to troubleshoot this issue?

• A. Check the DHCP client configuration to ensure it is enabled and properly configured to request IP addresses. Examine the logs for any errors.
• B. Re-flash the Bluefield OS image
• C. Restart the networking service using 'systemctl restart networking'.
• D. Manually assign static IP addresses to the interfaces using the 'ifconfig' command.
• E. Reinstall the Mellanox OFED drivers. A corrupted driver installation could cause network configuration issues.

Answer: A

Explanation:
In most modern systems, network interfaces are automatically configured using DHCP. Therefore, the first step is to check if the DHCP client is enabled and configured correctly. If DHCP fails, then other troubleshooting steps, such as static IP assignment or driver reinstallation, can be considered.

NEW QUESTION # 176
Which protocol is commonly used in Spine-Leaf architectures for dynamic routing and load balancing across multiple paths?

• A. ECMP (Equal-Cost Multi-Path)
• B. OSPF (Open Shortest Path First)
• C. STP (Spanning Tree Protocol)
• D. VRRP (Virtual Router Redundancy Protocol)
• E. BGP (Border Gateway Protocol)

Answer: A

Explanation:
ECMP (Equal-Cost Multi-Path) is crucial for efficiently utilizing the multiple paths available in a Spine-Leaf architecture. It allows traffic to be distributed across these paths, improving throughput and reducing congestion. OSPF and BGP can be used for routing but do not inherently provide per-packet load balancing. STP is used to prevent loops, and VRRP provides router redundancy, neither of which directly address load balancing across multiple equal-cost paths.

NEW QUESTION # 177
You have a deep learning application that requires a specific version of the CUDA toolkit inside the container. How should you best ensure that the correct CUDA version is available within the container, considering the NVIDIA Container Toolkit is installed on the host?

• A. Use a base image (e.g., from NVIDIA NGC) that already includes the desired CUDA toolkit version. This approach provides a consistent and reproducible environment.
• B. Install the required CUDA toolkit version directly on the host operating system. The NVIDIA Container Toolkit will automatically map it into the container.
• C. Manually copy the necessary CUDA libraries from the host into the container using 'docker cp' before running the application.
• D. Use the nvidia-container-cli to modify the existing image to install the proper cuda version.
• E. Specify the desired CUDA version when running the container using the '-env flag. The NVIDIA Container Toolkit will dynamically install the CUDA version during container startup.

Answer: A

Explanation:
The recommended approach is to use a base image that already contains the desired CUDA version. NVIDIA provides pre-built images on NGC (NVIDIA GPU Cloud) that are specifically designed for deep learning and include the appropriate CUDA versions and other dependencies. Installing CUDA on the host and expecting it to be magically mapped (A) is not reliable. The NVIDIA Container Toolkit doesn't install CUDA on the fly (B). Manually copying libraries (D) is error-prone and doesn't handle dependencies well. While technically possible, using nvidia- container-cli to modify the image is more complex than using a base image.

NEW QUESTION # 178
When deploying BlueField OS using PXE boot, which of the following files on the PXE server is responsible for specifying the kernel, initrd, and device tree files to be loaded by the client?

• A. /boot/grub/grub.cfg
• B. tftpboot/lpxelinux.0
• C. tftpboot/pxelinux.0
• D. pxelinux.cfg/default
• E. dhcpd .conf

Answer: D

Explanation:
The 'pxelinux.cfg/default' file (or a similar configuration file based on the client's MAC address or IP address) contains the configuration directives for the PXE bootloader, including specifying the kernel, initrd, and device tree files. 'dhcpd.conf is for DHCP server configuration, 'pxelinux.ff is the PXE bootloader itself, and '/boot/grub/grub.cfg' is a GRUB configuration file, usually on the client's disk.
