   An administrator suspects an MTU issue is causing packet drops on an NSX overlay network. Which diagnostic tool would most directly confirm this?

   • Anetstat on the source VM
   • Bping with the 'do not fragment' flag and a large packet size
   • Ctraceroute with a small packet size
   • Darp on the source ESXi host

   A VM on an overlay segment is experiencing intermittent connectivity to a physical server on the underlay network. The administrator has confirmed the overlay is healthy by pinging the T0 gateway's overlay interface. What is the next most logical step to isolate the issue?

   • ACheck the BGP session state between the T0 and the physical router.
   • BCheck the NSX Manager's health status.
   • CVerify the MTU settings on the physical switches.
   • DRun a packet capture on the T0 gateway's uplink interface.

   Two ESXi hosts in an NSX-T cluster cannot communicate over the overlay network. The administrator pings the TEP IP of each host from the other and the ping succeeds. What does this result indicate?

   • AThe underlay is healthy and the issue is in the overlay configuration
   • BThe underlay is broken and needs to be fixed
   • CThe TEP IPs are misconfigured
   • DThe overlay is healthy and the issue is in the physical network

   An administrator is troubleshooting a routing issue where a VM on an overlay segment cannot reach an external network. The T1 gateway's route table shows a default route via the T0, and the T0's route table shows a default route via a BGP peer. The BGP session is established. What is the most likely cause of the issue?

   • AThe NSX Edge node hosting the T1 is not in the same transport zone as the T0.
   • BThe T0 gateway's uplink interface is down.
   • CThe BGP peer is not advertising the default route.
   • DThe T1 gateway's route redistribution is not enabled.
