QuestionQ65

Network Virtualization

You choose to create only host routes for every virtual network in a project. Each virtual network receives its correct host prefix. While troubleshooting inter-VN connectivity with the ping command, the response times out between two virtual networks even though your policies permit the traffic.

What is the issue in this scenario?

  • A The VMs do not have interfaces.
  • B Using host routes prevents the default route from being sent.
  • C Your VMs have incorrect DNS settings.
  • D The IPAM settings are incorrect.
Explanation

When a virtual network is set to allocate only host routes, DHCP supplies VMs with host-specific /32 routes but withholds the default route (0.0.0.0/0) that would normally direct traffic destined for other subnets toward the vRouter gateway; without that default route, VMs have no path to reach other virtual networks, so ping between VNs times out even though the configured policies allow the traffic.
