You are managing a high-performance computing environment. Users have reported storage performance degradation, particularly during peak usage hours when both small metadata- intensive operations and large sequential I/O operations are being performed simultaneously.
You suspect that the mixed workload is causing contention on the storage system.
Which of the following actions is most likely to improve overall storage performance in this mixed workload environment?

• A. Reducing stripe count for large files would decrease parallelism, likely worsening performance for large sequential I/O operations.
• B. Separate metadata-intensive operations and large sequential I/O operations by using different storage pools for each type of workload.
• C. Disable GPUDirect Storage (GDS) during peak hours to reduce I/O load on the Lustre file system.
• D. Increase the number of Object Storage Targets (OSTs) to handle more metadata operations.

Which practice ensures that changes to machine learning models, datasets, and configuration files are tracked, reproducible, and auditable across development, testing, and production environments in an AI operations lifecycle?

• A. Load balancing
• B. Data labeling
• C. Containerization
• D. Version control

Your Kubernetes cluster is running a mixture of AI training and inference workloads. You want to ensure that inference services have higher priority over training jobs during peak resource usage times.
How would you configure Kubernetes to prioritize inference workloads?

• A. Set up a separate namespace for inference services and limit resource usage in other namespaces.
• B. Increase the number of replicas for inference services so they always have more resources than training jobs.
• C. Implement ResourceQuotas and PriorityClasses to assign higher priority and resource guarantees to inference workloads over training jobs.
• D. Use Horizontal Pod Autoscaling (HPA) based on memory usage to scale up inference services during peak times.

An administrator requires full access to the NGC Base Command Platform CLI.
Which command should be used to accomplish this action?

• A. ngc config BCP
• B. ngc config set
• C. ngc set API

Which type of drift occurs when the relationship between input features and target variables changes over time, even if the input data distribution remains relatively stable?

• A. Concept drift
• B. Label drift
• C. Data drift
• D. Feature drift
