LAN Switching Concepts! Trivia Quiz

LAN switching means switching of data packets, which are transferred from one computer to another over a network. They are vital to network design, as they permit the traffic to be sent only where it is required and helps to improve the overall efficiency of LAN. This quiz will test your overall knowledge about LAN Switching Concepts. So, let's try out the quiz. All the best!


Questions and Answers
  • 1. 
    10BASE2, 10BASE5, 10BASET.

      Hub doubles the available bandwidth of the network

    • F. 

      Bridge doubles the available bandwidth of the network

  • 4. 
    The IEEE defines 3 general categories of Ethernet MAC addresses 1 - Unicast 2 - Broadcast 3 - Multicast A)  A frame sent with a destination address of the broadcast address (FFFF.FFFF.FFFF) implies that all devices on the LAN should receive and process the frame B) Allow a dynamic subnet of devices on a LAN to communicate C) MAC addresses that identify a single LAN interface card
    • A.

  • 5. 
    (3) Primary functions of a switch are
    • A. 

      Routes the packet to appropriate device

    • B. 

      Learns MAC addresses based on SOURCE address

    • C. 

      Makes forwarding decision based on DESTINATION IP address

    • D. 

      Makes forwarding decision based on DESTINATION MAC address

    • E. 

      Uses STP (Spanning Tree Protocol) to prevents looping in a Layer 2 network environment

    • F. 

      Creates collision domains and doubles available bandwidth

  • 6. 
    We call Fast Ethernet 1 is the interface the hub connected to the switch. The switch in the picture has MAC addresses of all PC0, 1, 2, and 3 and all the interfaces that these PCs connected to. Suppose PC0 (connected to the hub) sends a frame to PC1 (also connected to the same hub). What will the switch do
    • A. 

      The switch forwards the frame from PC0 to PC1.

    • B. 

      The hub forwards the frame from PC0 to PC1.

    • C. 

      The switch discards the frame

    • D. 

      The hub simply regenerates the signal and forwards the frame to all connected interface, in this case it's PC1

  • 7. 
    The switch learns MAC addresses and interfaces by
    • A. 

      Examining the interface of the SOURCE MAC

    • B. 

      Examining the DESTINATION MAC address in the frame

    • C. 

      Examining the SOURCE MAC address in the frame

    • D. 

      Examining the interface of the DESTINATION MAC

  • 8. 
    We call Fast Ethernet 1 is the interface the hub connected to the switch. Suppose the switch has no MAC addresses for any of the PCs shown in the picture. Suppose PC0 (connected to the hub) sends a frame to PC2 (also connected to the same hub). What will the switch do
    • A. 

      The switch forwards the frame from PC0 to PC2

      The hub forwards the frame from PC0 to PC2

      The switch forwards the frame to PC2, and PC3

  • 9. 
    (Ignore the color of the connected cables) Suppose none of the switches has any MAC addresses of any PCs in the picture. PC0 is turned off. It cannot receive or send any thing.  When PC1 sends a frame to PC0. What will happen?
    • A.

    • B. 

      Switch 0 floods the frame to all connected interfaces

    • C. 

      Switch 3 floods the frame to all connected interfaces

    • D. 

      Switch 0 forwards the frame to PC0 and records the MAC of PC0 and the its connected interface

  • 10. 
    Switch Internal Processing ------------------------------------
    • 1 - Store and forward
    • 2 - Fragment-free
    • 3 - Cut-through
    • A - The switch fully receives all bits in the frame before forwarding the frame. This allows the switch to check the FCS before forwarding the frame.
    • B - The switch forwards the frame as soon as it can. This reduces latency but does not allow the switch to discard frames that fail the FCS check.
    • C - The switch forwards the frame after receiving the first 64 bytes of the frame, thereby avoiding forwarding frames that were errored due to a collision
    • A.
