  • Question
  • A switch has been configured for three different VLANs: VLAN2, VLAN3, and VLAN4. A router has been added to provide communication between the VLANs. What type of interface is necessary on the router if only one connection is to be made between the router and the switch?


  • Options
  • A. 10Mbps Ethernet
  • B. 56Kbps Serial
  • C. 100Mbps Ethernet
  • D. 1Gbps Ethernet

  • Correct Answer
  • 100Mbps Ethernet 

    Explanation
    Although you can use either 100Mbps or 1Gbps Ethernet, the 100Mbps is necessary at a minimum and is the best answer to this question. You need to trunk the link from the switch to the router to make this connection work with inter-VLAN communication.
