Question #: 13
Topic #: 2
An administrator is troubleshooting issues with an NVIDIA Unified Fabric Manager Enterprise (UFM) installation and notices that the UFM server is unable to communicate with InfiniBand switches.
What step should be taken to address the issue?
A.
Reboot the UFM server to refresh network connections.
B.
Install additional GPUs in the UFM server to boost connectivity.
C.
Disable the firewall on the UFM server to allow communication.
D.
Verify the subnet manager configuration on the InfiniBand switches.
Comprehensive and Detailed Explanation From Exact Extract:
Communication issues between UFM server and InfiniBand switches often result from misconfigured or missingsubnet manager configurationon the switches. The subnet manager controls fabric membership and routing, so verifying and correcting its setup is essential for proper UFM operation. Rebooting, adding GPUs, or disabling firewalls are less likely to resolve fabric-level communication problems.
