최신 NVIDIA-Certified Professional NCP-AIO 무료샘플문제 (Q62-Q67):

질문 # 62
You are monitoring the resource utilization of a DGX SuperPOD cluster using NVIDIA Base Command Manager (BCM). The system is experiencing slow performance, and you need to identify the cause.
What is the most effective way to monitor GPU usage across nodes?

A. Use nvidia-smi on each node to monitor GPU utilization manually.
B. Run the top command on each node to check CPU and memory usage.
C. Use the Base View dashboard to monitor GPU, CPU, and memory utilization in real-time.
D. Check the job logs in Slurm for any errors related to resource requests.

정답：C

설명：
Comprehensive and Detailed Explanation From Exact Extract:
TheBase View dashboardin NVIDIA Base Command Manager provides a centralized and real-time overview of GPU, CPU, and memory utilization across all nodes in the DGX SuperPOD cluster. This tool allows administrators to quickly identify bottlenecks and resource usage patterns efficiently, unlike manually checking logs or running commands node-by-node.

질문 # 63
You're managing a cluster using Kubernetes and Ceph, and your AI training jobs are experiencing storage I/O bottlenecks. You want to use Rook to manage Ceph within Kubernetes effectively. What configurations in Rook and Kubernetes would you verify to optimize storage performance for your AI workloads?

A. Configure Ceph placement groups (PGs) and pools to match the workload characteristics (e.g., number of objects, access patterns).
B. Modify Rook's default storage class to use the 'rbd' provisioner with optimized parameters for AI workloads (e.g., 'imageFeatures: layering'
C. Verify that the Kubernetes pods have appropriate resource requests and limits to prevent resource contention.
D. Ensure that the Ceph OSDs are running on fast storage devices (e.g., NVMe SSDs) and have sufficient resources (CPU, memory).
E. Disable Ceph monitoring within Rook to reduce overhead on the cluster. pool: data').

정답：A,B,C,D

설명：
OSD performance is crucial for Ceph's overall performance. Resource requests/limits prevent pod resource starvation. Optimizing PGs and pools aligns Ceph with the workload. Configuring vrbd' provisioner with optimized parameters will help improve overall performance. Monitoring is important to debug issues, do not disable.

질문 # 64
Which process ensures that input data used during inference is consistent with the data used during training, preventing discrepancies that could negatively affect model performance?

A. Data normalization
B. Feature store usage
C. Feature consistency
D. Data validation

정답：B

설명：
Feature stores ensure consistent feature definitions between training and inference. This prevents training-serving skew, a common issue where differences in data processing lead to degraded model performance in production.

질문 # 65
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?

A. Simultaneously upgrade the drivers on all nodes.
B. Use a Kubernetes DaemonSet to manage the driver installation and updates, ensuring a rolling update strategy.
C. Delete all pods on the node, upgrade the drivers, and then recreate the pods.
D. Upgrade the drivers on a single node and then propagate the changes to other nodes using a script.
E. Drain each node, upgrade the drivers, and then uncordon the node.

정답：B,E

설명：
The correct answers are A and E. Draining a node Ckubectl drain') gracefully evicts pods from the node before upgrading the drivers, and then uncordoning it ('kubectl uncordori) makes it available for scheduling again. Alternatively, a DaemonSet can manage the driver installation and updates, as a rolling upgrade strategy by design will restart pods one by one, ensuring minimum disruption. Options B and C cause downtime. Option D might work, but is not automated and thus not a best practice.

질문 # 66
You're deploying a DOCA-based firewall application on a BlueField-2 DPU. The application uses eBPF for packet filtering. What is the primary reason for using eBPF in this scenario?

A. To reduce CPU utilization on the host server by offloading packet filtering to the DPU.
B. To improve the compatibility with legacy network devices.
C. To automatically generate iptables rules on the host server.
D. To simplify the firewall rule definition using a higher-level language.
E. To enable dynamic updates to the firewall rules without requiring kernel module recompilation.

정답：A,E

설명：
eBPF allows offloading packet filtering to the DPU, thus reducing the load on the host CPU. It also allows dynamic updates to firewall rules without requiring kernel recompilation, which is a significant advantage in terms of flexibility and maintenance.
