An administrator is troubleshooting a problem with NSX.

When troubleshooting NSX on an ESXi host, VMware requires verification that NSX VIBs (vSphere Installation Bundles) are installed and in the correct state. VIBs are responsible for NSX datapath, control-plane modules, and kernel extensions on ESXi. The authoritative and documented method to list VIBs on an ESXi host is the command:

esxcli software vib list

This command displays all installed kernel modules, version numbers, NSX packages, and their installation status. For NSX-T (now part of VCF networking), administrators expect to see VIBs such asnsx-aggservice,nsx-bridge,nsx-esx-datapath, and others. If any required NSX VIBs are missing or inconsistent, the ESXi host will fail to join NSX transport nodes or will show “Not Ready.”

Option A (esxtop) is for performance monitoring and does not show VIB information.

Option C (nsxcli get version) checks NSX version on Edge Nodes or host transport nodes butdoes not list VIBs.

Option D (esxcfg software list) is an outdated and invalid command.
