   • BThe packet is routed by the Tier-1 DR on the source host directly to the destination host.
   • CThe packet is dropped because inter-segment routing requires a centralized router.

   A VM on an overlay segment can reach the internet, but traffic from the internet cannot reach the VM. The Tier-1 gateway has a NAT rule configured for the VM. The Tier-0 gateway has a default route to the physical router. What is the most likely cause of the issue?

   • AThe NAT rule is configured as SNAT only, so return traffic is not translated back to the VM's private IP.
   • BThe physical router does not have a route to the Tier-0 gateway's uplink subnet.
   • CThe Tier-0 gateway does not have a route to the VM's segment.
   • DThe VM's firewall is blocking inbound traffic.
