89. A network administrator adds the default-information originate command to the configuration of a router that uses RIP as the routing protocol. What will result from adding this command?

· The router will only forward packets that originate on directly connected networks.

· The router will not forward routing information that is learned from other routers.

· The router will be reset to the default factory information.

· The router will propagate a static default route in its RIP updates, if one is present.

· None of the above.

90. Refer to the exhibit. R1 is configured properly for a single area OSPF, and R2 has been recently installed in the network. Which set of commands is required to configure a single area OSPF for the networks that are connected to R2?

· R2(config)# router ospf 1
R2(config-router)# network 192.168.2.0 0.0.0.255 area 0
R2(config-router)# network 10.1.1.0 0.0.0.3 area 0

· R2(config)# router ospf 1
R2(config-router)# network 192.168.2.0 0.0.0.255 area 0
R2(config-router)# network 10.0.0.0 0.0.0.3 area 1

· R2(config)# router ospf 1
R2(config-router)# network 192.168.2.0 0.0.0.255 area 0
R2(config)# router ospf 2
R2(config-router)# network 10.1.1.0 0.0.0.3 area 0

· R2(config)# router ospf 1
R2(config-router)# network 192.168.2.0 0.0.0.255 area 0
R2(config-router)# network 10.1.1.0 0.0.0.3 area 1

· None of the above

91. Which command erase configurations which are stored in NVRAM memory?

· Delete NVRAM

· Delete running-config

· Erase NVRAM

· Erase startup-config

· Delete startup-config

92. Refer to the exhibit. If the EIGRP routing protocol is used throughout the network, which IP address and mask prefix should be sent by router R1 to the Edge router as a result of manual summarization of LANs A, B, C, and D?

· 192.168.4.0/24

· 192.168.4.0/26

· 192.168.4.0/20

· 192.168.4.0/22

· 192.168.4.0/23

93. Which prompt is used to allow a user to change the IP address of an interface on a router?

· Router(config)#

· Router(config-if)#

· Router>

· Router#

· None of the above

94. Refer to the exhibit. Which route will be installed in the routing table on R1 to forward traffic from PC1 to the web server?

· the route learned via OSPF

· the route learned via EIGRP

· the static route

· both routes learned via OSPF and EIGRP

· None of the above

95. Because of a topology change, the next hop IP address in the current static route must be reconfigured. How can a static route entry be altered to accommodate a topology change?

· Keep the existing static route, reload the router, and configure a new static route with the correct next hop IP address.

· Do nothing. The existing static route will automatically update the next hop entry with the new IP address.

· Keep the existing static route and configure a new static route with the correct next hop IP address.

· Negate the existing static route and configure a new static route with the correct next hop IP address.

· None of the above.

96. Refer to the exhibit. The hosts that are connected to R2 are unable to ping the hosts that are connected to R1. How can this problem be resolved?

· Configure a loopback interface on both routers.

· Configure the router ID on both routers.

· Configure the R2 router interfaces for area 0.

· Configure the proper subnet masks on the router interfaces.

· None of the above

97. Refer to the exhibit. Which solution provides the most efficient use of router resources for forwarding traffic between BR and HQ?

· RIP

· EIGRP

· Static routes

· RIPv2

· None of the above

98. Refer to the exhibit. Routers R1 and R3 use different routing protocols with default administrative distance values. All devices are properly configured and the destination network is advertised by both protocols.
Which path will be used to transmit the data packets from PC1 to PC2?

· The traffic will be load-balanced between two paths — via R2-R1 and via R2-R3.

· The packets will travel via R2-R3, and the other path via R2-R1 will be retained as the backup path.

· The packets will travel via R2-R1.

· The packets will travel via R2-R3.

· None of the above.

99. Refer to the exhibit. The network is configured with RIPv2. However, network administrators notice that communication cannot be successfully completed from one LAN to another. A network administrator issues the show ip route command on the HQ router. Based on the output, what should be done to correct the problem?

· Disable the load balancing feature of RIPv2.

· Replace RIPv2 with EIGRP which supports VLSM.

· Make sure that the network statements include the correct subnet mask.

· Issue the no auto-summary command for RIPv2.

· None of the above.

100. Which combination describes T568A UTP cable connection?

· Orange, white orange, green, white green, black, white black, blue,white blue

· White green, green, white orange, blue, white blue, orange, brown, white brown

· White green, green, white orange, blue, white blue, orange, white brown, brown

· White orange, orange, green, white green, blue, white blue, black, white black

· Orange, white orange, green, white green, black, white black, white blue, blue
