Refer to the exhibit. An engineer must extend VRF-Lite over a trunk to another switch for VLAN 70 (10.70.70.0/24) on port GigabitEtheret0/0 and VLAN 80 (10.80.80.0/24) on port GigabitEthernet0/1. Which configuration accomplishes this objective?
A.
interface GigabitEthernet0/0 no switchport ip vrf forwarding 70
ip address 10.70.70.1 255.255.255.0 ! interface GigabitEthernet0/1 no switchport ip vrf forwarding 80 ip address 10.80.80.1 255.255.255.0

The physical trunk ports are configured with simple trunk configuration. The vrf is associated under the vlan interfaces.
1)create vlans
2)create vrf definition
3)create vlan interface, assign vrf, then IP
4)configure the trunk and allow vlans as required
This is stupid. A brakes the trunk from the logical perspective,, you mover it from L2 to a routed port.
B is partially correcto. Because you brake the L2 as You kick out all other vlans.... The command does nota Say "add"
This seems incorrect as trunking implies dot1q. You may not need it, but the questions states "trunk" as an objective. So it is actually B in this case as L2 does not require any L3(IP) related config.
Could someone explain this question? It clearly says 'over a trunk', but how does one extend VRF over a trunk? Cisco is mixing routing and switching here.
Shouldn't the answer be B, as that's the only answer with an actual trunk configuration?
Vlan is L2 network segmentation, VRF is L3 network segmentation, the question indicate that they want VRF over the trunk line, then just configure the trunk associate with the vlan that VRF on
