Which three commands must you enter to create a trunk that allows VLAN 20? (Choose three)
A. Switch(config-if)#switchport mode dynamic auto
B. Switch(config-if)#switchport mode trunk
C. Switch(config-if)#switchport trunk allowed vlan 20
D. Switch(config-if)#switchport mode dynamic desirable
E. Switch(config-if)#switchport trunk encapsulation dotlq
F. Switch(config-if)#switchport trunk native vlan 20
but E its a router on a stick command
B,C,D
E is not supported in switch, its a command for router
A does not guarantee the trunk, depends of oposite side
F wrong ofcourse
B,C,E
sorry
“three commands must you enter”
you cannot enter E on a switch
sorry
you can if it is a switch virtual interface (avi)
svi
B,C,E is correct. you are asked to configure vlan 20 as the native vlan so this rules out of F
B,C,E is correct!
answer:B,C,E
Yup BCE
1) Switch(config-if)#switchport mode trunk (change from access to trunk)
2) Switch(config-if)#switchport trunk encapsulation dotlq (encapsulate)
2) Switch(config-if)#switchport trunk allowed vlan 20 ( Allow)
The native vlan is used to carry untagged traffic accross a trunk – but that has nothing to do with VLAN20 – so F is wrong.
You all are right its b c e.
correct answers are Items B-C-E, item F is wrong for the question.
E. Switch(config-if)#switchport trunk encapsulation dotlq
not F
