CCNA2 Chapter 5 Exam Answer 2016 v5.03

  1. What is a disadvantage of using router-on-a-stick inter-VLAN routing?

    • does not support VLAN-tagged packets
    • requires the use of more physical interfaces than legacy inter-VLAN routing
    • does not scale well beyond 50 VLANs
    • requires the use of multiple router interfaces configured to operate as access links
  2. How is traffic routed between multiple VLANs on a multilayer switch?

    • Traffic is routed via physical interfaces.
    • Traffic is routed via internal VLAN interfaces.
    • Traffic is broadcast out all physical interfaces.
    • Traffic is routed via subinterfaces.
  3. Refer to the exhibit. In this network design, which connection or connections if any, add the VLAN ID number if host H1 sends information to host H2?

    CCNA2 Chapter 5 v5.03 006

    • from G0/1 on the router to G1/2 on the switch
    • from the switch to H2
  4. What is a characteristic of legacy inter-VLAN routing?

    • Only one VLAN can be used in the topology.
    • The router requires one Ethernet link for each VLAN.
    • The user VLAN must be the same ID number as the management VLAN.
    • Inter-VLAN routing must be performed on a switch instead of a router.
