   A user on VLAN 10 (10.10.10.0/24) wants to reach a server on VLAN 20 (10.20.20.0/24). The topology shows: access switch → distribution switch → router (with subinterfaces for both VLANs) → firewall → server. Which path does the traffic take?

   • AUser → access switch → distribution switch → router → firewall → server
   • BUser → access switch → router → distribution switch → firewall → server
   • CUser → access switch → firewall → router → distribution switch → server
   • DUser → distribution switch → access switch → router → firewall → server

   • BAdd a second router and connect it to the existing switch.
   • CConfigure link aggregation between the PC and the switch.
   • DAdd a second internet connection to the existing router.
