VMware NSX 4.x Professional (2023) — Question 87

An NSX administrator is using ping to check connectivity between VM1 running on ESXi1 to VM2 running on ESXi2. The ping tests fails. The administrator knows the maximum transmission unit size on the physical switch is 1600.

Which command does the administrator use to check the VMware kernel ports for tunnel end point communication?

Answer options

• A. vmkping ++netstack=geneve -d -s 1572
• B. esxcli network diag ping -I vmk0 -H
• C. esxcli network diag ping -H
• D. vmkping ++netstack=vxlan -d -s 1572

Correct answer: D

Explanation

The correct answer is D because it specifically uses the vxlan netstack, which is relevant for checking tunnel endpoint communication in NSX. Options A and D both utilize vmkping, but only D targets the vxlan netstack, making it suitable for the NSX environment. Options B and C do not specify a netstack and are not focused on tunnel endpoint communication.
