Assignment 3

This assignment is based on CCNA Chapters 12-13.

  1. How long is the interpacket gap?

  2. Which station typically transmits the jam signal once a collision has been detected?

  3. Identify the devices used to create separate collision domains.

  4. Latency depends on media resistance, number of nodes and what else?

  5. What causes most Ethernet errors?

  6. What action may resolve a high collision rate on a network segment?

  7. The typical causes of late collisions are:

  8. Which class of 803.3 repeaters has higher latency?

  9. Of the two types of directional communication, which type does not loop back transmissions?

  10. How do routers typically handle broadcasts and multicasts?

  11. Give one reason why a switch provides increased security on a network.

  12. Identify the advantage that shared memory buffering has over port-based memory.

  13. Of the four switching modes, which one will propagate errors the most?

  14. True or false, a minimum-sized Ethernet packet essentially turns a fragment-free switch into a store-and-forward switch.

  15. Identify the layer two protocol designed to prevent switching/bridging loops.

  16. While configuring the logical path in an STP-enabled network any logical loops are removed. How is this accomplished?

  17. What are the two switch port states?

  18. All switch ports will be in one of two stable states when the network is completely configured. Identify the two states.

  19. The most common VLAN configuration is:

  20. Which type of VLAN is configured port-by-port?
