    If auto-negotiation fails because the attached device does not support it, the Catalyst switch defaults the switch port to half-duplex mode.
    • A. 

      True

    • B. 

      False

  • 7. 
    Half-duplex on one end and full-duplex on the other causes late collision errors at the half-duplex end.
    • A. 

      True

    • B. 

      False

  • 8. 
    With this feature enabled, the switch detects the interface required for copper media and configures the interface accordingly.
  • 9. 
    Switches use MAC addresses to direct network traffic to the appropriate port.
    • A. 

      True

    • B. 

      False

  • 10. 
    If a destination address is not in the table, the switch forwards the frame out all ports except the receiving port.
    • A. 

      True

    • B. 

      False

  • 11. 
    When two connected hosts want to communicate with each other, the switch uses the switching table to establish a connection between the ports. This provided maximum available bandwidth to both hosts, as if the network has only two hosts.

    • B. 

      Cut-through

    • C. 

      Straight-through

  • 18. 
    Store-and forward is the only method used on current Cisco Catalyst switches.
    • A. 

      True

    • B. 

      False

  • 19. 
    Any corrupt frames are still forwarded and consume network bandwidth in cut-through method.
    • A. 

      True

    • B.

  • 20. 
    In symmetric switching, all ports have the same bandwidth.
    • A. 

      True

    • B. 

      False

  • 21. 
    In asymmetric switching, more bandwidth can be assigned to a server to prevent bottlenecks.
    • A. 

      True

    • B. 

      False

  • 22. 
    In memory buffering, switch analyzes some or all of a packet before it forwards it to the destination host based on the forwarding method.
    • A. 

      True

    • B. 

      False

  • 23. 
    In port-based memory buffering, frames are stored in queues that are linked to specific incoming and outgoing ports.
    • A. 

      True

    • B. 

      False

  • 24. 
    In shared memory buffering, the switch deposits all frames into a common memory buffer that all the ports on the switch share. The amount of buffer memory required by a port is dynamically allocated.
