Q46. You are an administrator managing a large-scale Kubernetes-based GPU cluster using Run:AI.
To automate repetitive administrative tasks and efficiently manage resources across multiple nodes, which of the following is essential when using the Run:AI Administrator CLI for environments where automation or scripting is required?

Use the runai-adm command to directly update Kubernetes nodes without requiring kubectl.

Use the CLI to manually allocate specific GPUs to individual jobs for better resource management.

Ensure that the Kubernetes configuration file is set up with cluster administrative rights before using the CLI.

Install the CLI on Windows machines to take advantage of its scripting capabilities.

Q47. You want to upgrade your BCM installation to the latest version. What is the recommended approach for upgrading BCM in a production environment?

Simply run the installation script for the new version, overwriting the existing installation.

Back up the BCM database, then run the upgrade script provided with the new version, following the documented upgrade procedure.

Delete the existing BCM installation and reinstall the new version from scratch, restoring the database from backup.

Stop the BCM service, download the new version, and manually replace the binary files.

Upgrade the NVIDIA drivers on all GPU nodes before upgrading BCM.

Q48. You are tuning the storage performance of a Kubernetes cluster that uses Longhorn as the storage backend. You’ve noticed inconsistent read latencies. What Longhorn specific configurations could you adjust to potentially improve the consistency and reduce latency for read operations?

Increase the number of replicas for each Longhorn volume to improve data redundancy and read parallelism.

Adjust the ‘replica-auto-balance’ setting to redistribute replicas more evenly across nodes.

Enable ‘data locality’ to ensure that replicas are preferably placed on the same node as the pod accessing the volume, reducing network latency.

Reduce the size of the Longhorn volumes to decrease the amount of data that needs to be read.

Disable Longhorn’s built-in monitoring to reduce overhead.

Q49. You want to upgrade the NVIDIA drivers on your Kubernetes nodes without disrupting the running AI workloads. What is the recommended approach to perform a rolling upgrade of the NVIDIA drivers?

Drain each node, upgrade the drivers, and then uncordon the node.

Simultaneously upgrade the drivers on all nodes.

Delete all pods on the node, upgrade the drivers, and then recreate the pods.

Upgrade the drivers on a single node and then propagate the changes to other nodes using a script.

Use a Kubernetes DaemonSet to manage the driver installation and updates, ensuring a rolling update strategy.

Q50. An AI data center is dealing with exponentially growing unstructured dat a. Which of the following storage architectures is the most cost-effective and scalable solution for long-term data archival and retrieval?

A high-performance parallel file system with NVMe SSDs.

A distributed database system with built-in replication.

JBODs (Just a Bunch Of Disks) directly attached to each compute server.

Q51. You are troubleshooting slow training times for a deep learning model. You suspect the storage is the bottleneck. You are using a network file system (NFS) to serve the dat a. Which of the following NFS mount options would most likely improve performance for read- heavy workloads?

Using the ‘sync’ mount option.

Using the ‘async’ mount option.

Reducing the ‘rsize’ (read size) and ‘wsize’ (write size) to the smallest possible value.

Mounting the NFS share with the ‘nolock’ option.

Increasing the ‘rsize’ and ‘wsize’ to the maximum supported values by the NFS server and client.

Q52. You are troubleshooting a cluster with NVIDIA NVLink and NVSwitch. The fabric manager service (‘nvsm’) appears to be running, but the NVLink topology is not being discovered correctly. What is the FIRST step you should take to isolate the issue?

Immediately restart all GPUs in the system.

Check the ‘/var/log/nvsm/nvsm.log’ file for any error messages or warnings.

Reinstall the NVIDIA drivers.

Increase the logging level of ‘nvsm’ to DEBUG and restart the service.
