VMware Exam 2V0-41.23 Topic 14 Question 15 Discussion

Actual exam question for VMware's 2V0-41.23 exam

Question #: 15
Topic #: 14

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?

Aesxcli network diag ping -I vmk0O -H <destination IP address>

Bvmkping ++netstack=geneve -d -s 1572 <destination IP address>

Cesxcli network diag ping -H <destination IP address>

Dvmkping ++netstack=vxlan -d -s 1572 <destination IP address>

Suggested Answer: B

The commandvmkping ++netstack=geneve -d -s 1572 <destination IP address>is used to check the VMware kernel ports for tunnel end point communication. This command uses the geneve netstack, which is the default netstack for NSX-T. The-doption sets the DF (Don't Fragment) bit in the IP header, which prevents the packet from being fragmented by intermediate routers. The-s 1572option sets the packet size to 1572 bytes, which is the maximum payload size for a geneve encapsulated packet with an MTU of 1600 bytes. The<destination IP address>is the IP address of the remote ESXi host or VM.References: : VMware NSX-T Data Center Installation Guide, page 19. : VMware Knowledge Base: Testing MTU with the vmkping command (1003728). : VMware NSX-T Data Center Administration Guide, page 102.

This question seems pretty straightforward. We need to find the correct command to check the VMware kernel ports for tunnel end point communication when the ping test fails and the MTU size on the physical switch is 1600.
