8. What types of messages are sent periodically by devices configured for CDP? probes

beacons signals advertisements routing updates unicast

9. An administrator has made routing protocol changes to a routers configuration. To ensure that the changes are implemented, the active configuration is saved and the router is reloaded. After the router has initialized, the output on the screen displays "Would you like to enter the initial configuration dialog?[yes/no]:" Why did this dialog appear? There was a POST failure. The incorrect IOS loaded. There was an error in the startup configuration file. The configuration register was set to ignore NVRAM.

10. Which command is used to redirect debug information to a device that is connected though a Telnet session? Router# monitor Router# terminal redirect vty 0 Router# terminal monitor Router# monitor output vty 0

11. After issuing the show interfaces command, a technician notices the line "Serial1 is down, line protocol is down" in the output. Which of the following are possible reasons for this message output? (Choose three.) There is a mismatch in the encapsulation type on both ends of the link. A Layer 1 issue exists. An interface problem exists. The clockrate was not set during configuration.

There is no usable media for the protocol. Keepalive messages are not being sent.

12.

Refer to the above graphic. When using RIP as the routing protocol, how would Chicago use load balancing to route packets to New York? (Choose two.) by forwarding packets over paths of equal cost by forwarding packets according to hop count and speed of the link by determining which interface has the least traffic and sending to it first by first determining the speed of the links and then cycling packets through the fastest links first by cycling packets through interfaces and routes following the same pattern (Router 1, 2, 3) each time

13. When would the ROM monitor mode be used? (Choose two.) maintaining routing configuration settings modifying the IOS image stored in Flash running a limited IOS feature set performing the bootstrap process

14. Which two statements are true about route metrics? (Choose two.)

The more factors that make up a metric, the greater the flexibility to tailor network operations. The larger the metric number, the better the path. Routing protocols use metrics to send routing updates to directly connected neighbors. Bandwidth and delay are static metrics used by RIP v1. Ticks, delay, and cost are metrics used by routing protocols.

15.

Which of the following are valid static IP routes? (Choose three.) RouterB(config)# ip route 192.168.5.0 255.255.255.0 S1 RouterC(config)# ip route 192.168.1.0 255.255.255.0 S1 RouterA(config)# ip route 192.168.3.0 255.255.255.0 192.168.2.2 RouterB(config)# ip route 192.168.1.0 255.255.255.0 192.168.2.2 RouterC(config)# ip route 192.168.2.0 255.255.255.0 192.168.4.1 RouterA(config)# ip route 192.168.4.0 255.255.255.0 192.168.2.1

16. Of the eight network users on the Human Resources department LAN, one cannot connect to the file server. The users PC has successfully booted but can not see the network. What should be checked first? the PC power cord the file server the PC network interface card LEDs

the LAN switch in the wiring closet the configuration of the router interface attached to the LAN

17. What can be determined from the partial output of the show ip routecommand displayed below? (Choose two.) R 200.200.200.0/24 [120/1] via 192.168.10.2, 00:00:14, Serial0/0 C 192.168.10.0/24 is directly connected, Serial0/0 The next update will be in 76 seconds. The next update will be in 16 seconds. The administrative distance is 120 and the metric is 1. The metric is 120 and the administrative distance is 1. 200.200.200.0 is configured on Serial0/0. 192.168.10.2 is configured on Serial0/0.

18. Why is it useful to have an interface description? A user can telnet to the router using the interface description. The interface description is a shortcut way to edit the running-config. The interface description helps identify distant network connections. The interface will remain inactive until an interface description is applied.

19.

Assume OSPF is being used on all routers. What happens when the link between Router1 and Router2 goes down? (Choose two.) Updates start broadcasting every 30 seconds. Updates start broadcasting every 90 seconds. Link-state advertisements are flooded. Link-state advertisements are sent only to neighboring routers. All routers note the change and adjust routes. All routers ignore the change until the route becomes active again.

20.

The internetwork needs to communicate between the hosts connected to the E0 interface of the Utah router and hosts connected to the E0 interface of the Idaho router. The hosts should also have connectivity to the Internet. Which commands must be configured in order to enable this communication? (Choose three.)

21. Which statement about datagram life is true? Each router increments the TTL value of the datagram until the maximum hop count of the routing protocol is reached. The packet is then returned to the source. The packet is dropped when the router count and the TTL value match. The source is notified that transmission has failed. Each router decreases the TTL value by one until it reaches zero. The datagram is then discarded and a time exceeded for message is sent to the source. The destination device discards the datagram if the TTL value is zero on arrival. An ICMP destination unreachable message is sent back to the source.

22.
