Which commands will allow a trunk with another switch configured as mode desirable auto?

A.	SwitchB(config-if)# switchport trunk encapsulation dot1q
	SwitchB(config-if)# switchport mode trunk
B.	SwitchB(config-if)# switchport mode dynamic auto
	SwitchB(config-if)# switchport mode encapsulation dot1q
C.	SwitchB(config-if)# switchport nonegotiate
D.	SwitchB(config-if)# switchport encapsulation dot1q
	SwitchB(config-if)# switchport mode trunk

A. You must first set the encapsulation to 802.1Q, then you can statically set the mode to trunk. An alternative would be to set the port to dynamic desirable via the command switchport mode dynamic desirable. However, it is recommended to statically configure the link to trunk on one or both sides if possible.
