Free EMC NCP-AII Exam Dumps Questions & Answers

After updating BlueField-3 DPU BMC firmware via Redfish, the engineer observes "TaskState:
Running" but no progress after 15 minutes. How should they track the update's completion status?

• A.Run bfrec -status on the DPU to view flash progress.
• B.Query the DPU BMC with the Task ID of the installation process.
• C.Check /var/log/messages on the DPU OS for update logs.
• D.Power cycle the DPU immediately to force a rollback.

While trying to bring-up the fabric, the administrator identifies one nonoperational InfiniBand server:

What is the cause based on the output?

• A.The HCA port is faulty.
• B.The HCA port is not assigned a LID numer.
• C.The HCA port is not part of the InfiniBand fabric.
• D.OpenSM is not running on the fabric.

A DGX server reports degraded performance and storage alerts. How would you use NVSM (NVIDIA System Management) and nvidia-smi to troubleshoot both system and GPU issues?

• A.Start by issuing nvidia-smi -L to list GPUs, followed by nvsm --refresh to clear all alerts, and nvidia-smi -q to get detailed GPU information.
• B.Use nvsm show health for a system health summary, nvsm show storage for storage issues, and nvidia-smi -q to get detailed GPU information.
• C.Run nvsm reset to restore system health, then use nvidia-smi --fix for automatic GPU repairs and status recovery.
• D.Run nvsm collect-stats to gather logs, use lsblk to understand if there are storage problems, and nvidia-smi -q to get detailed GPU information.

An administrator needs to add additional GPUs to an existing server. What are the server requirements to check before installing new GPUs?

• A.Sufficient storage, sufficient networking, adequate power of rack, and compatible hardware.
• B.Sufficient CPU capacity, PCI slot allocation, sufficient cooling in the data center, and rack space.
• C.Sufficient cooling in the data center, adequate power of rack compatible hardware, and PCI slot allocation.
• D.Sufficient networking, water-cooled racks, adequate power of rack, sufficient storage, and rack space.

After upgrading to HPL-AI 2.0 on a DGX A100 cluster, a 2x performance gain is observed. Which optimization is primarily responsible for this improvement?

• A.Automatic NVLink bandwidth doubling via driver updates.
• B.MPI-aware GPU communication that reduces CPU bottlenecks and GPU idle time.
• C.Doubting of GPU clock speeds through firmware updates and relevant configuration.
• D.Reduction of problem size (N) to accelerate computation.
