Both VM-A and VM-B use the same Distributed Router for their default gateway.

Based on the exhibit, if VM-A sends a packet to VM-B,what happens to the packet before it reaches VM

B?

A. Distributed Router in Host-A receives the packet from VM-A and forwards it to Logical Switch 7775 in Host-B, via a VXLAN frame, which delivers it to VM-B.

B. Logical Switch 7321 in Host-A receives the packet inside a frame from VM-A and forwards it to Logical Switch 7775 in Host-B, via a VXLAN frame, which delivers it to VM-B.

C. Distributed Router in Host-A receives the packet from VM-A and forwards it to Logical Switch 7321 in Host-B, via a VXLAN frame, which delivers it to Logical Switch 7775 before it is delivered to VM-B.

D. Logical Switch 7321 in Host-A receives the packet from VM-A and forwards it to the Distributed Router in Host-B, which passes it along to Logical Switch 7775 in Host-B before it is delivered to VM-B.
