Question 30
UnclassifiedYou need to generate an InfiniBand fabric health report that checks routing correctness, identifies any duplicate GUIDs, and validates that all expected nodes are present in the topology.
Correct answer: C
Explanation
ibdiagnet is the InfiniBand diagnostic tool used to analyze fabric health and topology. It checks routing correctness, reports duplicate GUIDs, and verifies that expected nodes are present in the fabric, making it the right choice for a comprehensive health report.
Why each option is right or wrong
A. ibstat
B. perfquery
C. ibdiagnet
`ibdiagnet` is the Mellanox/NVIDIA InfiniBand fabric diagnostics utility designed to interrogate the subnet manager and topology, then produce a fabric health report covering route validation, GUID consistency, and node inventory. In practice it flags duplicate GUIDs, checks that the discovered topology matches the expected fabric, and reports missing or unexpected nodes; these checks are part of its standard diagnostic output rather than a separate add-on tool.
