A. ACCESS1(config)# line console 0 ACCESS1(config-line)# password cisco B. Remote27(config)# line console 0 Remote27(config-line)# login

Remote27(config-line)# password cisco C. ACCESS1(config)# line vty 0 4 ACCESS1(config-line)# login

ACCESS1(config-line)# password cisco D. Remote27(config)# line vty 0 4 Remote27(config-line)# login

88. Refer to the exhibit. Subnet 10.1.3.0/24 is unknown to router RTB. Which router command will prevent routerRTB from dropping a packet destined for the 10.1.3.0/24 network if a default route is configured?

A. ip classless B. ip default-network C. network 10.1.1.0

D. network 10.1.1.0 0.0.0.255 area 0 Answer: A

89. Refer to the exhibit. The network shown in the exhibit is running the RIPv2 routing protocol. The network hasconverged, and the routers in this network are functioning properly. The FastEthernet0/0 interface on R1 goesdown. In which two ways will the routers in this network respond to this change? (Choose two.)

A. All routers will reference their topology database to determine if any backup routes to the 192.168.1.0 network are known.

B. Routers R2 and R3 mark the route as inaccessible and will not accept any further routing updates from R1 until their hold-down timers expire.

C. Because of the split-horizon rule, router R2 will be prevented from sending erroneous information to R1 aboutconnectivity to the 192.168.1.0 network.

D. When router R2 learns from R1 that the link to the 192.168.1.0 network has been lost, R2 will respond bysending a route back to R1 with an infinite metric to the 192.168.1.0 network.

E. R1 will send LSAs to R2 and R3 informing them of this change, and then all routers will send periodic updatesat an increased rate until the network again converges.

Answer: CD

C. 1 - Ethernet rollover cable 2 - Ethernet crossover cable 3 - serial cable 4 - null modem cable

D. 1 - Ethernet straight-through cable

2 - Ethernet crossover cable 3 - serial cable 4 - rollover cable

E. 1 - Ethernet straight-through cable 2 - Ethernet crossover cable 3 - serial cable

4 - Ethernet straight-through cable Answer: B

92. Refer to the exhibit. A network administrator attempts to ping Host2 from Host1 and receives the results thatare shown. What is a possible problem?

A. The link between Host1 and Switch1 is down. B. TCP/IP is not functioning on Host1

C. The link between Router1 and Router2 is down. D. The default gateway on Host1 is incorrect. E. Interface Fa0/0 on Router1 is shutdown. F. The link between Switch1 and Router1 is down. Answer: C

93. What does the \Global\address represent in the configuration of NAT?

A. the summarized address for all of the internal subnetted addresses

B. the MAC address of the router used by inside hosts to connect to the Internet C. a globally unique, private IP address assigned to a host on the inside network D. a registered address that represents an inside host to an outside network Answer: D

94. During startup, the router displays the following error message:boot: cannot open \

A. Because of damaged flash memory, the router will fail the POST.

B. It will attempt to locate the IOS from a TFTP server. If this fails, it will initiate the setup dialog.

C. It will attempt to locate the IOS from a TFTP server. If this fails, it will load a limited IOS from ROM.

D. It will attempt to locate the configuration file from a TFTP server. If this fails, it will initiate the setup dialog.

E. It will attempt to locate the configuration file from a TFTP server. If this fails, it will load a limited configuration from ROM.

Answer: C

95. Refer to the exhibit. S0/0 on R1 is configured as a multipoint interface to communicate with R2 and R3 in this hub-and-spoke Frame Relay topology. While testing this configuration, a technician notes that pings aresuccessful from hosts on the 172.16.1.0/24 network to hosts on both the 172.16.2.0/25 and 172.16.2.128/25networks. However, pings between hosts on the 172.16.2.0/25 and 172.16.2.128/25 networks are not successful.What could explain this connectivity problem?
