=========================
Use this at your own risk.
I'm not responsible for
what you do with it.
Happy cheating ^^
=========================


===========================================================================

time exceeded
redirect
destination unreachable*
source quench
parameter problem

===========================================================================
Which two are true regarding the debug commands? (Choose two.)

Debug commands may be issued from the user EXEC prompt.
The command undebug all will turn off all debug operations.*
By default, the router sends the debug output and messages to the telnet session.
The high processor overhead incurred using debug may disrupt normal router operation.*
The debug all command provides a summary view of router activity and can be used frequently for troubleshooting.
The show debugging command will display current events such as traffic on an interface and error messages generated by nodes on the network.
===========================================================================
Which of the following commands can be used to statically configure default routes? (Choose two.)

ip static-route
ip route*
ip network-route
ip default-network*
ip default-static
===========================================================================
At which OSI layer does the routing of email packets from the source network to the destination network occur?

session
transport
network*
===========================================================================
When issuing the show interfaces serial1 command, a network administrator receives the output shown in the graphic. What are the possible causes of an increase in the number of input errors? (Choose three.)

There could be Layer 3 addressing problems.
There could be a problem with faulty telephone equipment.*
The router hardware could be defective.*
There is an incorrectly configured encapsulation on the interface.
There could be a problem with the cabling.*
===========================================================================
Which two are true regarding the output shown in the graphic? (Choose two.)

Network 192.168.44.0 is 610 routers away from the source router.
A packet destined for host 192.168.80.24 will be forwarded out the Serial0 interface.*
The subnet mask for the networks is 255.255.255.240.
The router is receiving IGRP updates through its serial interface.*
This router is using three different routing protocols.
===========================================================================
The show interfaces command provides line and protocol status information. Which of the following conditions would never occur in the output of this command?

serial1 is up, line protocol is up
serial1 is up, line protocol is down
serial1 is down, line protocol is down
serial1 is down, line protocol is up*
serial1 is administratively down, line protocol is down
===========================================================================
After issuing the command traceroute 192.168.4.2 from Router A, the following information is returned.
Tracing the route to Router_D (192.168.4.2)
1 Router_B (192.168.2.2) 16 msec 16 msec 16 msec
2 * * *
3 * * *
What can be concluded about the network shown in the graphic based on the output given?

Network 192.168.5.0 is missing from the routing table on Router A.
There is a problem with the connection between Router B and Router C.*
Router C is not running CDP.
Some of the routers are non-Cisco devices.
Router B was not able to return ICMP TEMs to Router A.
===========================================================================
During the lookup process when forwarding a packet, a router checks its routing table for the best path to the destination. If a route has an administrative distance of 0, what does this indicate to the router?

The packet should be discarded.
The destination is unreachable.
The destination is a directly connected network.*
The source of the update for that route is unreliable.
===========================================================================
Which of the following would be the default administrative distance of a static IP route that references the IP address of the next hop?

0
1*
5
20
===========================================================================
Which items would be displayed when the show ip protocol command is executed? (Choose three.)

sources of routing updates*
networks being advertised*
routing protocol up or down
configured routed protocols
Layer 2 status of the interface
update timer values*
===========================================================================
A network administrator suspects that a network is not being included in the routing updates. Which command will provide information on when the next update is due and which networks are advertised in the update?

Router# show interfaces
Router# show controllers serial
Router# show ip protocols*
Router# show ip route
Router# show running-config
===========================================================================
Which of the following lines from the show interfaces output would indicate a Layer 2 problem?

Serial1 is up, line protocol is up.
Serial1 is up, line protocol is down.*
Serial1 is down, line protocol is down.
Serial1 is administratively down, line protocol is down.
===========================================================================
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.
===========================================================================
Refer to the network graphic. A packet needs to travel from Router F to Router A. Which path would be selected by the RIP routing protocol if the default metrics are used?

F, G, E, D, B, A
F, E, D, C, A
F, E, D, A*
F, E, D, B, A
===========================================================================
Which command will verify the functionality of all seven layers of the OSI model on a network host?

ping
telnet*
tracert
debug
===========================================================================
Why does a router build a routing table? (Choose two.)

to list available routes for forwarding data*
to map local Layer 2 addresses to the remote Layer 3 destination address
to dynamically send periodic updates regarding the router's status
to prevent routing loops when redundant links are added to the network
to select the best path to a destination*
===========================================================================
Which of the following are advantages of using a static route? (Choose three.)

secure operation *
highly adaptable
low maintenance configuration
low processor overhead*
precise control of path selection*
===========================================================================
After issuing the show interfaces serial1 command, an administrator notices an increasing number of carrier transitions. What are the possible causes for this increase? (Choose two.)

There is an incorrect encapsulation configured on the interface.
There could be an interruption in the line by the service provider.*
There is a faulty switch or CSU/DSU.*
There is noise on the serial line.
===========================================================================
Which command will display routing table information about all known networks and subnetworks?

Router# show ip interfaces
Router# show ip connections
Router# show ip route*
Router# show ip networks
===========================================================================
Consider the RIP network shown in the diagram. Which entries would be listed in the routing table of Router A?

R 192.168.5.2[120/1] via 192.168.15.0, 00:00:09, Serial0
R 192.168.15.0[120/1] via 192.168.5.2, 00:00:13, Serial1
R 192.168.15.0[120/1] via 192.168.5.1, 00:00:13, Serial0*

R 192.168.15.0 [120/1] via 192.168.5.2, 00:00:29, Serial1
R 192.158.5.1 [120/1] via 192.168.5.2 00:00:18, Serial0
R 192.168.15.2 [120/1] via 192.168.5.2, 00:00:18, Serial
===========================================================================
The network administrator shown in the graphic can ping the E0 interface of the HAR router, but the telnet intranet.xyz.com command issued from her workstation fails to open a session with the intranet.xyz.com server. Which of the following could cause this problem? (Choose two.)

upper-layer application problems*
domain name system problems*
IP debugging problems
IP routing problems
