  19. Why is the MTU for a PPPoE DSL configuration reduced from 1500 bytes to 1492?

    • to enable CHAP authentication
    • to reduce congestion on the DSL link
    • to accommodate the PPPoE headers
    • to establish a secure tunnel with less overhead
  20. What are two characteristics of a PPPoE configuration on a Cisco customer router? (Choose two.)

    • The PPP configuration is on the dialer interface.
    • An MTU size of 1492 bytes is configured on the Ethernet interface.
    • The Ethernet interface does not have an IP address.
    • The customer router CHAP username and password are independent of what is configured on the ISP router.
    • The dialer pool command is applied to the Ethernet interface to link it to the dialer interface.
  21. Fill in the blank.

    DOCSIS specifies the   MAC         sub-layer as a Layer 2 requirement that defines either a deterministic access method, TDMA, or S-CDMA.

  22. Fill in the blank. Use only an acronym.
    PPPoE               creates a PPP tunnel through the DSL connection for the purpose of sending PPP frames.

  23. Match each type of broadband wireless technology with the correct description. (Not all options are used.)CCNA4_Ch6_001
