Answer: AB

Explanation:

A & B are right

1- after applying the question command: switchport trunk allowed vlan 1, 80, 99-250

Switch(config)#do show int trunk

Port Mode Encapsulation Status Native vlan

Fa0/1 on 802.1q trunking 1

Port Vlans allowed on trunk

Fa0/1 1,80,99-250

Port Vlans allowed and active in management domain

Fa0/1 1 Port Vlans in spanning tree forwarding state and not pruned

Fa0/1 1

now after applying “except 100”:

Switch(config-if)#switchport trunk allowed vlan except 100

Switch(config-if)#do show int trunk

Port Mode Encapsulation Status Native vlan

Fa0/1 on 802.1q trunking 1

Port Vlans allowed on trunk

Fa0/1 1-99,101-1005

Port Vlans allowed and active in management domain

Fa0/1 1

Port Vlans in spanning tree forwarding state and not pruned

Fa0/1 none you can see that except 100, allowed all vlans except 100, which is against what is required in the question
