NVIDIA NCP-AII Exam - Topic 3 Question 10 Discussion

Actual exam question for NVIDIA's NCP-AII exam

Question #: 10
Topic #: 3

A cluster administrator needs to validate transceiver firmware versions across 200 ports using UFM. Which GUI-based method provides a consolidated view?

ANavigate to 'Devices' > select a switch > 'Cables' tab to see ASIC firmware and transceiver versions.

BUse 'Topology' view to visually inspect cable icons.

CRun mlxlink -d lid-<LID> -m on each port manually.

DExport all switch logs and grep for 'FW Version'.

Show Suggested Answer

Suggested Answer: A

Managing a large-scale AI fabric requires centralized visibility into the physical layer. The NVIDIA Unified Fabric Manager (UFM) provides a comprehensive Dashboard for InfiniBand networks. To check transceiver firmware---which is critical for ensuring feature parity and stability across the fabric---the administrator can use the UFM Enterprise GUI. By navigating to the 'Devices' section and selecting a specific switch, the 'Cables' tab will aggregate telemetry for every occupied port. This view displays the manufacturer, part number, and the specific firmware version of the transceivers (LinkX) or Active Optical Cables (AOC). This consolidated view is far more efficient than manual CLI queries (Option C) for 200+ ports. Maintaining uniform firmware across transceivers ensures that optimizations like Adaptive Routing and Congestion Control perform consistently across the entire 400G or 200G fabric.

I think option A sounds familiar since we practiced checking firmware versions in the lab, but I'm not entirely sure if it gives a consolidated view.
