Switch A is configured with the command of switchport mode dynamic desirable on its interface. Which command would you need to configure on Switch B to create a trunk between them?

A. SwitchB(config-if)# switchport mode dynamic auto
B. SwitchB(config-if)# switchport mode dynamic desirable
C. SwitchB(config-if)# switchport mode trunk
D. All of the above

D. The command switchport mode dynamic desirable is similar to switchport mode dynamic auto with the exception that it is desirable to become a trunk. So if the neighboring port is set to auto, desirable, or trunk, it becomes a trunk.
