  VRFs are not needed for "router on a stick", The Answer is C.

• Chose C2

  We need to remove VRF forwarding to advertise the VLAN networks from the global routing table. Inter-VLAN routing techniques: (1) Router on a stick: The router's interface connected to the switch, which has multiple VLANs, is configured to use subinterfaces to route traffic between the different VLANs). (2) SVI (switch virtual interface): A L3 switch routes traffic between the VLANs utilizing a virtual interface for each VLAN. The router will be used to advertise the VLAN networks to external networks. The example above is not a traditional router on a stick, It describes a Layer 3 switch configured with SVIs ('interface VLAN 10, 20, and 30' commands) to route traffic between the different VANs.

  hahaha, I thought it would configure a route leak between different VRFs, the answer told me just to delete the vrf directly!!
