NEW QUESTION # 31
You are configuring BCM for cluster provisioning. You want to automate the installation of specific software packages on each newly provisioned node. How can you achieve this?
- A. Use a BCM post-provisioning script to install the packages.
- B. Create a Kubernetes Job that runs on each node to install the packages.
- C. Include the package installation commands directly in the OS image.
- D. Leverage a configuration management tool like Ansible or Chef within a BCM post-provisioning script.
- E. Specify the packages in the 'cluster.yamr file under the 'packages' section.
Answer: A,C,D
Explanation:
Including packages in the OS image is a direct approach. Post-provisioning scripts allow customization after the base OS is installed. Configuration management tools offer more sophisticated automation. Kubernetes Jobs are designed for workload execution, not system-level package management. BCM does not have a 'packages' section in 'cluster.yamr for direct package specification.

NEW QUESTION # 33
A data scientist has provided you with a Jupyter Notebook running inside an NGC container. This notebook relies on a large dataset stored in an object storage service (e.g., AWS S3, Google Cloud Storage). What's the most efficient and secure way to provide the notebook access to this data without embedding credentials directly into the notebook or container image?
- A. Utilize Kubernetes Secrets to store the object storage credentials and mount them as files into the container.
- B. Create a custom Docker image that includes the object storage SDK and hardcodes the credentials.
- C. Mount the object storage as a network drive on the host system and then mount this drive into the container.
- D. Leverage Identity and Access Management (IAM) roles or Service Accounts associated with the Kubernetes cluster to grant the container access to the object storage.
- E. Use environment variables to pass the object storage credentials to the container.
Answer: A,D
Explanation:
C and E are the most secure and efficient. Kubernetes Secrets allow for secure storage and management of sensitive data, which can be mounted into the container as files. Leveraging IAM roles or Service Accounts allows the container to inherit permissions from the Kubernetes cluster, eliminating the need for explicit credentials. Option B is less secure as environment variables can be easily exposed. Option A can introduce performance bottlenecks. Option D is highly discouraged due to security risks and lack of flexibility.

You have deployed a VMI container with Triton Inference Server on a cloud provider that supports MIG (Multi-lnstance GPU). You have a single A100 GPU and you want to partition it into two MIG instances to serve two different models concurrently, each requiring half of the GPU's resources. What steps are necessary to achieve this?
- A. Partition the AIOO GPU into two MIG instances using the 'nvidia-smi' command-line tool, then configure Triton to use each MIG instance separately by specifying the corresponding UUIDs in the model configuration files.
- B. MIG is not a supported feature in Triton
- C. Bake different drivers in Triton Container to target different MIG instances
- D. Configure the cloud provider's instance settings to automatically partition the GPU into MIG instances.
- E. No special configuration is needed; Triton automatically detects and utilizes MIG instances.
Answer: A
Explanation:
To utilize MIG with Triton, you need to first partition the GPU into MIG instances using 'nvidia-smi' , and then configure Triton to use each MIG instance separately. This involves specifying the correct UUIDs for each MIG instance in the model configuration files, allowing Triton to isolate and utilize each partition effectively.

NEW QUESTION # 38
You are running a distributed TensorFlow training job on your Kubernetes cluster. The job consists of a parameter server and multiple worker pods. To maximize GPU utilization and ensure efficient communication, you want to place the parameter server and workers on nodes that are as close as possible within the network topology. Which Kubernetes feature can assist you in achieving this?
- A. Topology Spread Constraints.
- B. Pod anti-affinity.
- C. NodeSelector.
- D. Pod Priority.
- E. Resource Quotas.
Answer: A
Explanation:
The correct answer is C. Topology Spread Constraints allow you to control how pods are spread across your cluster based on topology domains like nodes, racks, or zones. By specifying the relevant topology domain (e.g., for nodes), you can encourage the scheduler to place related pods (parameter server and workers) on the same or nearby nodes. Pod anti-affinity (A) would work to keep pods separated. NodeSelector (B) can place pods on specific nodes, but doesn't inherently understand network topology. Resource Quotas (D) and Pod Priority (E) don't directly address pod placement based on network proximity.
NEW QUESTION # 39
You have a Kubernetes cluster running AI workloads. The pods are experiencing intermittent storage performance issues, particularly when writing checkpoints. You are using a Container Storage Interface (CSI) driver for your storage. How would you go about troubleshooting this issue, focusing on the CSI driver and Kubernetes interaction?
- A. Monitor the performance metrics of the underlying storage system (e.g., IOPS, latency, throughput) to identify any bottlenecks.
- B. Examine the logs of the CSI driver controller and node components for errors or warnings related to volume provisioning, attachment, and detachment.
- C. Check the Kubernetes events related to the PersistentVolumeClaims (PVCs) used by the pods for any storage-related errors or delays.
- D. Restart all pods in the cluster to clear any potential caching issues.
- E. Check kubernetes component logs such as kube-scheduler for any failures in scheduling the pods
Answer: A,B,C
Explanation:
The CSI driver logs provide insights into storage operations initiated by Kubernetes. Examining Kubernetes events related to PVCs can reveal errors during provisioning or attachment. Underlying storage metrics highlight performance bottlenecks. Restarting all pods is a bad idea and should not be done unless you have a very good reason.
NEW QUESTION # 40
You have a Run.ai cluster integrated with NVIDIA's Cluster Manager (ACM). A data scientist reports that their job is being preempted frequently, even though they have a high-priority quot a. What are the MOST likely reasons for this preemption, assuming ACM is configured correctly?
- A. The node where the job is running is being drained for maintenance.
- B. A higher priority job is requesting resources and preemption is enabled for that queue.
- C. Another job with a higher guaranteed quota and higher priority needs the resources.
- D. The job is exceeding its memory limits.
- E. The job is using an outdated CUDA driver version.
Answer: A,B,C
Explanation:
Preemption in Run.ai with ACM is typically triggered by: Another job with a higher guaranteed quota and higher priority needing the resources (ACM prioritizes based on quota and priority). The node being drained (Kubernetes initiates preemption to safely evacuate pods before maintenance). A higher priority job needing resources and preemption is enabled. Exceeding memory limits usually results in an 00M error, not preemption. An outdated CUDA driver could cause errors, but not typically preemption. Note that OOM can occur on containers when the available memory is exhausted, which can cause them to be killed

Answer: C
Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
NVIDIA Fabric Manager manages the NVLink and NVSwitch fabric resources within HGX systems, enabling efficient resource allocation, communication, and virtualization necessary for AI/ML workloads.
This is critical for virtualization as it ensures optimized interconnect performance between GPUs. Video encoding, graphical rendering, or memory upgrades are outside the scope of Fabric Manager.
NEW QUESTION # 42
A Kubernetes pod running a GPU-accelerated application is failing to start. The pod's logs show the error message 'Failed to initialize NVML: Driver/library version mismatch'. What are the MOST likely causes of this issue?
- A. The Kubernetes version is incompatible with the NVIDIA drivers.
- B. The GPU is not properly seated in the server.
- C. The NVIDIA driver version on the host is incompatible with the CUDA version used in the container image.
- D. The 'nvidia-container-runtime' is not properly configured on the Kubernetes nodes.
- E. The Docker daemon is not running.
Answer: C,D
Explanation:
A 'Driver/library version mismatch' error strongly suggests an incompatibility between the host's NVIDIA driver and the CUDA libraries in the container. Improper configuration of the 'nvidia-container-runtime' (which handles GPU access for containers) is also a likely cause. While a loose GPU (C) would prevent GPU access altogether, it's less likely to cause this specific error. The Docker daemon (D) is essential for containers, but this specific error points to NVIDIA-related issues. Kubernetes version incompatibility (E) is possible, but less common than driver/CUDA mismatch.
NEW QUESTION # 43
After successfully creating MIG instances on your NVIDIA A100 GPU, you observe that applications assigned to these instances are not fully utilizing the allocated resources. You suspect that CPU affinity is not properly configured. What steps should you take to ensure optimal CPU affinity for these MIG instances?
- A. Disable CPU affinity altogether to allow processes to migrate freely across all cores.
- B. Rely solely on the operating system's default scheduler to handle CPU affinity.
- C. Manually assign CPU cores to each MIG instance using the 'taskset' command or similar tools, ensuring that each instance has exclusive access to its assigned cores. Also use numactl.
- D. Set CPU affinity to the same core for all MIG instances.
- E. Increase the priority of all processes running within the MIG instances using the snice' command.
Answer: C
Explanation:
CPU affinity binds processes to specific CPU cores, reducing context switching and improving performance. Manually assigning CPU cores to each MIG instance, ensuring exclusivity, is crucial for optimal resource utilization. 'tasksets and 'numactl' are commonly used tools for this purpose. Options A, C, D, and E would likely lead to performance degradation or resource contention.
NEW QUESTION # 44
You are managing a large Slurm cluster used for AI research. You notice that some users are submitting jobs that request excessive amounts of memory, even though their applications don't actually need it, leading to inefficient resource utilization. What steps can you take to address this issue and encourage users to request more appropriate memory resources?
- A. Adjust the scheduler's priority algorithm to penalize jobs that request excessive memory.
- B. Configure Slurm's accounting system to track memory usage and provide reports to users, highlighting inefficient memory requests.
- C. Educate users on how to accurately estimate their memory requirements and provide tools for monitoring memory usage.
- D. Implement strict memory limits per job and automatically kill jobs that exceed those limits.
- E. All of the above
Answer: E
Explanation:
A multi-faceted approach is needed. Enforcing limits (A) prevents waste, education (B) helps users improve requests, accounting (C) provides feedback, and adjusting priority (D) discourages wasteful requests. A, B, C, D combined provide the best approach.
NEW QUESTION # 45
A system administrator needs to scale a Kubernetes Job to 4 replicas.
What command should be used?
- A. kubectl scale job --replicas=4
- B. kubectl autoscale deployment job --min=1 --max=10
- C. kubectl stretch job --replicas=4
- D. kubectl scale job -r 4
Answer: A
Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
The correct command to scale a Kubernetes Job to a specific number of replicas iskubectl scale job -- replicas=4. This explicitly sets the number of desired pod instances for the Job resource. The other commands are either invalid (stretch), apply to Deployments rather than Jobs (autoscale deployment), or use incorrect syntax (-r).
