out its neighbors and their links and flooding this information to all of the other routers in the network.

c. All routers using a Link State protocol will have the same topology map of the network.

d. Best routes are determined dynamically starting with the lowest MAC address.

e. Convergence can take a very long time, as every router must build a new topological map.

　

11. A brand new Cisco router has no configuration defined. Which of the following is not a method that can be used to configure the router for the first time?

a. By connecting to the console port and suing TFTP to download a configuration file that has been created ahead of time.

b. By connecting to the console port and running the Setup dialogue.

c. By connecting to the console port and directly typing in configuration commands.

d. Using SNMP via a network management station.

e. Using bootp in conjunction with SLARP/RARP to download a configuration file that has been created ahead of time.

　

12. Which of the following EXEC commands is used to list a router s configuration stored in NVRAM?

a. list configuration

b. show nvram

c. show configuration

d. write configuration

e. write terminal

　

13. Which command places a copy of the active configuration into NVRAM?

a. write configuration

b. save

c. write nvram

d. copy config nvram

e. write memory

　

14. Which command places a copy of the active configuration into FLASH memory?

a. write flash

b. save

c. write memory

d. copy config flash

e. None of the above

　

15. If there were a high number of collisions this may be caused by:

a. Possible unterminated link

b. Impedance mismatch

c. Too many hosts on the ring

d. Software error

e. Transceiver jabber

　

16. A network administrator has lost the passwords to their Cisco router. How can this password be retrieved?

a. Call the Cisco Technical Assistance Center (TAC). Under software support, all passwords must be registered.

b. For the modular systems (AGS+, AGS+, MGS, CGS, IGS) and Cisco 7000: Power off router, move jumper on configuration register or toggle dipswitch to enter test

mode. When the router is powered back on, it will

automatically enter test mode, and the contents of NVRAM can be examined.

c. For the Cisco 3000 and Cisco 4000: Cold start or warm start the system and hit the break key while the system is booting. The router will go into ROM monitor

mode. Change the software registers, boot the router and check the contents of NVRAM.

d. Log onto the router and do a "write erase" to empty the contents of NVRAM. New passwords and then be configured.

e. Both (b) and (c)

　

17. What effect would this configuration command have: line vty 0 4 no password vtypassword

a. All telnet connections to the router will be denied

b. Only one telnet connection at the router will be allowed at a time

c. Virtual terminal sessions will not be able to enter enable mode

d. Virtual terminal sessions will not be asked a user level password

e. No effect

In anticipation of connecting other sites to the network, the leased serial line

between Router A and Router B is replaced by an X.25 network. The X.121 address

assigned to Router A is 31373105551212 and X.121 address assigned to Router

B is 3137408767399.

　

18. What configuration changes need to be made to Router A and Router B?

a. Ther serial interface needs to be changed to "encapsulation x25"

b. The X.121 address needs to be configured

c. The correct packet size, window size and timers need to be set to match the X.25 network

d. The X.25 map commands must be configured for each protocol being sent through the X.25 network.

e. All of the above

　

19. What X.25 map statements need to be added to Router B?

a. x25 map ip 193.8.1.1 31373105551212

b. x25 map ip 193.8.150.2 31373105551212

c. x25 map ip 193.8.150.1 31373105551212

d. x25 map ip 193.8.150.0 31374089767399

e. x25 map ip 193.8.2.1 31374089767399

　

20. Which type of IP routing would be the most economical over the X.25 network?

a. RIP

b. IGRP

c. OSPF

d. Static

e. The one with the best metric.
