An administrator has created several virtual machines on the same host server and requires them to each be on separate vlans. which of the following should the administrator configure to meet this goal?
a. set the vlan preferences on the host's nic
b. create each vlan on the host's virtual switch
c. change the virtual machine nic settings from private to bridged
d. create each vlan on the host's gateway router

B. Create each VLAN on the host's virtual switch.

Explanation:

A VLAN (virtual local area network) is a virtual interface, in which a physical port must belong to. By default, all ports on a network switch is configured to the interface VLAN 1.

This SVI (switch virtual interface) can be more than one on a switch. when a trunk line is created between two switches or a vitual machine is created on a host, it means that there is a need to create links for this new collision domain. So a Vlan must be created on the switch for the virtual machines configured on the host server.
