B. Switch(config)# switchport trunk encapsulation ietf
C. Switch(config)# switchport trunk encapsulation dot1q
D. Switch(config-if)# switchport trunk encapsulation isl
Answer: Option E
Solution(By Examveda Team)
If you are on a 2950 switch, then the interface command is justswitchport mode trunk, since the 2950 can only run the IEEE 802.1Q version. However, a 3550 can run both ISL and 802.1Q, so you must use the encapsulation command. The argument to choose 802.1Q for a trunking protocol is dot1q.
