An emergency-management NOC wants one primary daily view of InfiniBand link and bandwidth health. What should they select?
Select an answer to reveal the explanation.
Short Explanation
Reviewing nightly ibdiagnet and perfquery exports as a daily health view doesn’t give you a continuous, fabric-wide IB health view. Pick UFM as the emergency-management NOC’s primary InfiniBand link and bandwidth monitoring platform. DCGM dashboards for GPU telemetry can’t be your primary IB link health source because they show GPU metrics, not InfiniBand link or bandwidth status.
Full Explanation
An emergency-management NOC that wants one primary daily view of InfiniBand link and bandwidth health should select UFM as the primary InfiniBand link and bandwidth monitoring platform. UFM aggregates IB topology, link status, and utilization into an operational console suitable for recurring civic watch, while nightly ibdiagnet and perfquery exports reviewed as a daily health view are batch-oriented snapshots that cannot replace a continuous, unified NOC console. That matches the stem’s need for a primary daily IB health view.
Relying on nightly ibdiagnet and perfquery exports reviewed as a daily health view fails because they provide only periodic snapshots, lack real-time alerting, and are hard to institutionalize as the sole fabric-wide watch for NOC shifts. DCGM dashboards for GPU telemetry as the primary IB link health source fail because DCGM reports GPU metrics rather than InfiniBand link status or bandwidth utilization, so it cannot serve as the primary IB health view. Using Spectrum WJH alone as a full substitute for InfiniBand UFM fails because WJH targets Spectrum/Ethernet congestion forensics, not primary IB link/bandwidth monitoring.
Exam caveat: WJH and Ethernet platforms can complement campus networks, but the exam answer for primary InfiniBand daily health is UFM. Operational check: put UFM link and bandwidth views on the emergency-management NOC daily checklist and treat nightly ibdiagnet and perfquery exports as secondary diagnostics when UFM flags an issue, not as the primary daily view.
