103.Refer to the exhibit. Subnet 10.1.3.0/24 is unknown to router RTB. Which router command will prevent router RTB 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

Correct Answers: A

104.Refer to the exhibit. The network shown in the exhibit is running the RIPv2 routing protocol. The network has converged, and the routers in this network are functioning properly. The FastEthernet0/0 interface on R1 goes down. 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 about connectivity 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 by sending 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 updates at an increased rate until the network again converges.

Correct Answers: C, D

105.Which statement accurately describes a benefit provided by VTP?
A: VTP allows routing between VLANs.
B: VTP allows a single port to carry information to more than one VLAN.

D: VTP allows switches to share VLAN configuration information.

Correct Answers: D

2 - Ethernet straight-through cable
3 - fiber optic cable
4 - rollover cable
B: 1 - Ethernet straight-through cable
2 - Ethernet straight-through cable
3 - serial cable
4 - rollover cable
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

Correct Answers: B

107.Refer to the exhibit. A network administrator attempts to ping Host2 from Host1 and receives the results that are 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.

Correct Answers: C

108.What does the "Inside 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

Correct Answers: D

109.During startup, the router displays the following error message:
boot: cannot open "flash:"
What will the router do next?
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.

Correct Answers: C

110.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 are successful from hosts on the 172.16.1.0/24 network to hosts on both the 172.16.2.0/25 and 172.16.2.128/25 networks. 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?



A: The ip subnet-zero command has been issued on the R1 router.
B: The RIP v2 dynamic routing protocol cannot be used across a Frame Relay network.
C: Split horizon is preventing R2 from learning about the R3 networks and R3 from learning about the R2 networks.
D: The 172.16.2.0/25 and 172.16.2.128/25 networks are overlapping networks that can be seen by R1, but not between R2 and R3.
E: The 172.16.3.0/29 network used on the Frame Relay links is creating a discontiguous network between the R2 and R3 router subnetworks.

Correct Answers: C
