Virtual machine (VM) A is connected to virtual switch A, and VM B is connected to
virtual switch B.
Which statement is true about the network traffic between A and B?
A.
Traffic between VM A and VM B stays within ESX Server.
B.
Traffic between VM A and VM B flows through the physical NIC.
C.
VM A can communicate with VM B if they have same port group policies.
D.
VM A can communicate with VM B if they have same security policies.
Explanation:
VMware Virtual Networking Concepts, page 5.
Network traffic cannot flow directly from one virtual switch to another virtual switch
within the same host.
Therefore an external switch is required.
