Refer to the exhibit.
SwitchC connects HR and Sales to the Core switch. However, business needs require that no traffic from the Finance VLAN traverse this switch.
Which command meets this requirement?
A. SwitchC(config)#vtp pruning vlan 110
B. SwitchC(config)#vtp pruning
C. SwitchC(config)#interface port-channel 1 SwitchC(config-if)#switchport trunk allowed vlan add 210,310
D. SwitchC(config)#interface port-channel 1 SwitchC(config-if)#switchport trunk allowed vlan remove 110

I have never seen in Cisco CLI “switchport trunk allowed vlan remove ”
If anything it should be “switchport trunk allowed vlan add 210,310.”
That was the the port will be in hybrid mode and will eliminate Vlan 110 from PO1 because it is not mentioned in config.
So the right answer should be C
Or since this switch is in trasnparent mode remove the vlan 110 compleately from this switch since the goal is “no traffic from the Finance VLAN traverse !!this switch!!.”
There is a command “switchport trunk allowed vlan remove”
In the port-config would look like:
“switchport trunk allowed vlan 1-109,11-4096”
{…output omitted…] should mean, there are more vlans, so C would leave some vlans not assigned to the trunk.
D is correct.
