lx Answers to the Assessment Questions 46. D. Backward-Explicit Congestion Notification (BECN) is used to send information back to an originating router telling it to slow down its transfer rate because the switch is congested. See Chapter 10 for more information on Frame Relay. 47. D. Data Link Connection Identifiers (DLCIs) are used to identify a PVC through a Frame Relay switch. See Chapter 10 for more information on Frame Relay. 48. B, C. You can add multiple encapsulations on an interface either by using the secondary command or by creating a subinterface. See Chapter 8 for more information on IPX and multiple encapsulations. 49. B. 50 seconds is the default time for changing from blocking to forwarding state. This is to allow enough time for all switches to update their STP database. For more information on STP, see Chapter 2. 50. D. You can telnet to a 1900, but not from a 1900 switch CLI. See Appendix B for an explanation of the 1900 switch commands. 51. D. To delete the dynamic entries in a MAC address table, use the command clear mac-address-table dynamic from privileged mode. See Appendix B for an explanation of the 1900 switch commands. 52. B, C. By typing delete nvram, you delete the startup-config. However, this does not delete the VTP configuration on the switch. You must also type delete vtp. See Appendix B for more information on the 1900 switch commands. 53. C. The ports 26 and 27 are considered A and B when viewing trunk information. See Appendix B for more on the 1900 switch commands. 54. A. The command show vtp statistics will give you the receive and transmit statistics of VTP on a switch. See Appendix B for an explanation of the 1900 switch commands.
