A router has two FastEthernet interfaces and needs to connect to four VLANs in the local network. How can this be accomplished using the fewest number of physical interfaces without unnecessarily decreasing network performance?

  • Implement a router-on-a-stick configuration.
  • Add a second router to handle the inter-VLAN traffic.
  • Use a hub to connect the four VLANS with a FastEthernet interface on the router.
  • Interconnect the VLANs via the two additional FastEthernet interfaces.

Explanation: Using legacy inter-VLAN routing to interconnect four VLANs would require four separate physical interfaces. Therefore, the best router-based solution is to configure a router-on-a-stick.
