Refer to the exhibit. Why are users from VLAN 100 unable to ping users on VLAN 200?
A.
Encapsulation on the switch is wrong.
B.
Trunking needs to be enabled on Fa0/1.
C.
The native VLAN is wrong.
D.
VLAN 1 needs the no shutdown command.
E.
IP routing needs to be enabled on the switch.
I disagree, default encapsulation is ISL so I think answer A is right
you need a trunk before you even think about encapsulation
B seems right. Cisco routers do not support DTP. So it will not negotiate the trunking mode.
Plus ISL is not supported on newer Cisco switches and i believe it’s no longer the default encapsulation on some platforms.
The answer is B ( right )
The problem is the diagram, it is not clear, Fa 0/1 of the switch and fa0/0 of the router should be pointed on the diagram.
The configuration of the fa 0/0 is do1q encapsulation, so the configuration of the switch should be do1q also.
