QUESTION 81 One of your trainees asked you which parameter must be supplied when initializing the IGRP routing process. What is your response?
A. Connected subnet numbers
B. Register administrative subnet masks
C. IP address mask
D. Autonomous system number
E. Metric weights Answer: D Explanation: You configure IGRP just like RIP, except that the router igrp command has an additional parameter - the autonomous system (AS) number. The term autonomous system refers to a network that is within the control of a single company or organization. The term AS number refers to a number assigned to a single company or
organization when it registers its connection to the Internet. However, for IGRP, you do not need a registered AS number. All that is needed for IGRP to work is for all the routers to use the same AS number. Reference: CCNA Self-Study CCNA ICND exam certification Guide (Cisco Press, ISBN 1-58720-083-X) Page 165
QUESTION 82 Which of the following devices can you use to segment a network? (Select three options.)
A. hub
B. repeater
C. bridge
D. switch
E. router Answer: C D E Explanation Reference: CCNA Self-Study CCNA ICND exam certification Guide (Cisco Press, ISBN 1-58720-083-X) Page
QUESTION 83 Study the Exhibit below carefully:
ppp authentication chap ppp authentication chap After considering the command output of both routers, what is the cause of the problem if connectivity cannot be established between the two routers?
A. Authentication needs to be changed to PAP for both routers.
B. Serial ip addresses of routers are not on the same subnet.
C. Username/password is incorrectly configured.
D. Router names are incorrectly configured. Answer: C Explanation: Look at the passwords configured on the router Cisco Highway1 and Cisco Highway2, it is "cisco". When configuring for CHAP authentication, you must enters the other router's user name and password. In this case on router Cisco Highway2 has entered incorrect router Cisco Highway1's password, witch is "cisco1" (it must be "cisco"). As a result CHAP authentication will be faille, therefore couldn't a connection established between the routers.

QUESTION 84 Study the Exhibit below carefully:
In the illustration, Host Cisco Highway1 is trying to communicate with Host Cisco Highway2. The e0 interface on Cisco HighwayC is down. Which of the following are true? (Select two options.)
A. Cisco HighwayC will make use of ICMP to inform Host 1, Cisco HighwayA, and Cisco HighwayB that Host 2 is unreachable.
B. Cisco HighwayC will send a Destination Unreachable message type.
C. Cisco HighwayC will make use of ICMP to inform Host 1 that Host 2 is unreachable.
D. Cisco HighwayC will use ICMP to inform Cisco HighwayB that Host 2 is unreachable.
E. Cisco HighwayC will issue a Router Selection message type.
F. Cisco HighwayC will issue a Source Quench message type. Answer: B, C Explanation ICMP is an error-reporting protocol for IP. When datagram delivery error occur, ICMP reports these errors to the sender of the datagram. When the e0 interface on Cisco Highway C goes down, Cisco Highway C uses ICMP to send a message back to Cisco Highway 1 indicating that the datagram could not be delivered. ICMP does not correct the encountered network problem. Cisco Highway C will not notify the intermediary devices of the delivery failure. Therefore, Cisco Highway C will not send ICMP messages to Cisco Highway B. Datagrams contain only source and destination IP addresses, they do not contain information about all the intermediary devices. The reporting device ( Cisco Highway C) has only the sender's IP address with which to communicate. Although Cisco Highway A and B are not notified directly, they might become aware of the down interface on Cisco Highway C. However, disseminating this information to neighbor routers is not the function of ICMP. ICMP reports on the status of the delivered packet to the sender, its function is not to propagate information about network changes.
QUESTION 85 You are a network technician at Cisco Highway, Inc. You have completed the password recovery procedure on a Cisco router successfully and the router returned to normal operation. What is configuration register value at this point in time?
A. 0x2112
B. 0x2104
C. 0x2102
D. 0x2101 E. 0x2100 Answer: C Explanation: It is default factory setting. Router should attempt to load an IOS from flash memory and load startup configuration file. Flash memory also called NVRAM Incorrect answers
A: It is ROM Monitor mode. A low level problem determination
B: Router to boot from ROM
D: The value 0x2142 to be set for configuration register in case of password recovery procedure
QUESTION 86 You are a network technician at Cisco Highway, Inc. You are using a switch to break up a broadcast domain. Which features of the switch enables this?
A. Transparent bridging
B. Cut-through bridges
C. Fragment-free switches
D. Micro segmentation
E. Virtual LANs
F. Store-and-forward switching Answer: E Explanation: Creation of VLAN in a switch provide separate Broadcast domain. If VLAN is not there all ports as members of one Broadcast domain. Reference: Wendell Odom. CISCO CCNA Certification Guide ( 2000 Press) Page 172 Incorrect Answers
A: Transparent bridging is called Transparent because the endpoints devices do not need to know that the bridges exists. It will not play any role for creating separate broadcast domain B,D: Both are switching methods in a switch.
C: This is one of the Switching methods in a switch. It will not play any role for creating separate broadcast domains
F: Not related to the question

QUESTION 89 You are a network technician at Cisco Highway and have to locate and fix a router problem. Scenario is as follows: There are three routers named Cisco Highway1, Cisco Highway2, and Cisco Highway3 respectively. You know that Cisco Highway2 and Cisco Highway3 are 100% operational. The routing protocol being used is Single area OSPF. Cisco Highway1 has recently been installed and configured one of the trainees. However, he did not succeed in configuring Cisco Highway1 correctly. He tells you that connectivity is not complete because routing tables are not being updated correctly. You must now locate and fix this router configuration problem.
