14. Refer to the exhibit. The command ip route 0.0.0.0 0.0.0.0 S0/0/0 is run on router R2. What are the two results of this command? (Choose two.)
A static route will be updated in the routing table.

The traffic from the source network 172.16.0.0/22 will be blocked.
The route will be specified as the default route for all networks not defined in the routing table.
All the broadcasts will be forwarded via the S0/0/0 interface of R2.
43. Refer to the exhibit. A network administrator is investigating why data packets with destination addresses of 172.16.10.10 and 192.168.10.100 are being dropped instead of being forwarded via the static route as expected. After confirming that the ip classless command has been applied on all routers in the network, what other action should the administrator take to ensure that data packets to these addresses are forwarded via the static route?
Check that all routers are configured with the same autonomous system number.
Issue the no auto-summary command within the EIGRP configuration of all routers.
Issue the no passive-interface command within the EIGRP configuration of all routers.
Configure the static route to point to the next hop address instead of the outbound interface.
36. 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.
Issue the no auto-summary command for RIPv2.
Replace RIPv2 with EIGRP which supports VLSM.
Make sure that the network statements include the correct subnet mask
37. Which protocol is used by EIGRP to deliver and receive update packets?
FTP
RTP
TCP
TFTP
UDP
45. A network administrator configures a new router and saves the configuration. The router is taken to the installation site and installed. On startup, what component will the router search first by default for the saved configuration?
CompactFlash
CPU
boot ROM
flash
NVRAM
UART
30. Refer to the exhibit. Routers R1 and R2 are directly connected through a FastEthernet link but cannot form a neighbor adjacency. What could resolve the problem?
The cost on R1 should be set higher.
The priority on R1 should be set higher.
The OSPF process ID numbers must match.
A backup designated router needs to be added to the network.
The hello and dead timers must be configured with the same values on both routers.
38. Which multicast address does EIGRP use to send hello and updates packets?
224.0.0.5
224.0.0.6
224.0.0.9
224.0.0.10
39. A network administrator is using an application that is monitoring packets on the network and sees an EIGRP update packet. What is the purpose of the update packet?
The packet is sent to discover neighbors within the EIGRP network.
The packet is sent to search for network devices within an EIGRP network.
The packet is used to propagate routing information within the EIGRP network.
The packet is used to send an unreachable reply to another router within the EIGRP network.
The packet is used to notify all routers that EIRGP has failed on one of the routers within the EIGRP network
40. Refer to the exhibit. What OSPF network statements are required for the router B to advertise the three networks that are attached?
router ospf 1 network 10.0.0.0 0.0.0.255 area 0
router ospf 1 network 10.1.1.0 0.3.255.255 area 0 network 10.10.1.0 0.255.255.255 area 0 network 10.20.1.0 0.255.255.255 area 0
router ospf 1 network 10.1.1.0 0.0.0.3 area 0 network 10.10.1.0 0.0.255.255 area 0 network 10.20.1.0 0.0.255.255 area 0
router ospf 1 network 10.1.1.0 0.0.0.3 area 0 network 10.10.1.0 0.0.0.255 area 0 network 10.20.1.0 0.0.0.255 area 0
41. Refer to the exhibit. Why is the state of the serial0/0/0 interface administratively down?
An IP address has not been configured on the interface.
The WIC was installed into the incorrect slot on the router.
The default encapsulation on the interface has been modified.
The no shutdown command has not been executed on the interface
42. On a router, which three components are stored in RAM? (Choose three.)
POST code
the routing table
the running-configuration
the start-up configuration
the bootstrap instructions
a copy of the operating system
43. Refer to the exhibit. RouterA and RouterB cannot successfully exchange EIGRP routes. What is the problem?
The hello intervals do not match.
The autonomous system numbers do not match.
The no auto-summary command is missing from both routers.
The ip bandwidth-percent command is missing from RouterB
44. Refer to the exhibit. What is the purpose of the ip bandwidth-percent eigrp 50 10 command?
to limit the bandwidth EIGRP packets can use to 6.4 kb/s
to limit the bandwidth EIGRP packets can use to 10 kb/s
to limit the bandwidth EIGRP packets can use to 32 kb/s
to limit the bandwidth EIGRP packets can use to 50 kb/s
45. 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 be reset to the default factory information.
The router will not forward routing information that is learned from other routers.
The router will propagate a static default route in its RIP updates, if one is present.
The router will only forward packets that originate on directly connected networks
46. A network technician is configuring a Cisco 2811 router. The technician types conf at the privileged level command prompt and presses the TAB key. What action will the router take?
It will revert to the user mode.
It will perform an auto-complete function.
It will go into the global configuration mode.
It will give an error message that indicates a bad command was entered
47. What is a function of the console port on a router?
It is used to manage the router.
It is used for packet receiving and forwarding.
It is used to interconnect various types of LANs.
It is used to interconnect a variety of serial links including T1, DSL, and ISDN
48. Refer to the exhibit. Which route will be installed in the routing table on R1 to forward traffic from PC1 to the web server?
