2 A network technician has isolated a problem at the transport layerofthe OSI model. Which question would provide further informationaboutthe problem?
Do you have a firewall that is configured on your PC?
Do you have a link light on your network card?
Is your PC configured to obtain addressing information using DHCP?
What default gateway address is configured in your TCP/IP settings?
Can you ping
www.cisco.com?
3 Refer to the exhibit. A network administrator is in the processofsending a preconfigured text file to a router. When theadministratorpastes the configuration into the router, an error messageappears.What is the problem with the IP addressing scheme?
Serial0/0 is configured with a network address.
The IP address on FastEthernet0/0 overlaps with the IP on FastEthernet0/1.
Serial0/1 is configured with a broadcast address.
The IP address on FastEthernet0/0 overlaps with the IP on Serial0/1.
4 A user can access any web page on the Internet but cannotaccesse-mail. What troubleshooting method would be most efficientfortroubleshooting this issue?
top-down
bottom-up
divide-and-conquer
impossible to determine from this information
5 Refer to the exhibit. What are two possible causes for the interface status? (Choose two.)
The loopback address is not set.
The encapsulation type is mismatched.
A cable is not attached to the interface.
Keepalive messages are not being received.
The interface is administratively shut down.
6 Refer to the exhibit. Host H1 on the LAN is not able to access theFTPserver across the Internet. Which two configuration statementsarecausing this problem? (Choose two.)
There is no route to the Internet.
The IP address on Fa0/0 is incorrect.
The IP address on S0/0/0 is incorrect.
The NAT command on the Fa0/0 interface is applied in the wrong direction.
The NAT command on the S0/0/0 interface is applied in the wrong direction.
7 Which two conditions identify issues that are confined to Layer 1? (Choose two.)
cables that exceed maximum length
encapsulation errors
viruses and worms that create excessive broadcast traffic
poor termination of cables
receiving "line protocol down" messages on the router console
8 A network administrator is upgrading a Cisco 1841 router by addingaWIC-2T module card. Which show command can the administrator usetoverify that the module is correctly recognized by the router?
show flash:
show version
show ip route
show startup-configuration
9 Hosts on two separate subnets cannot communicate. Thenetworkadministrator suspects a missing route in one of the routingtables.Which three commands can be used to help troubleshoot Layer3connectivity issues? (Choose three.)
Ping
show arp
traceroute
show ip route
show controllers
show cdp neighbor
10 Refer to the exhibit. Which statement is true regarding the IP address configuration?
Interfaces Fa0/0 and Fa0/1 can be in the same subnet.
Interface Fa0/0 and NetworkA can be in the same subnet.
Interface Fa0/0 and NetworkB can be in the same subnet.
Interface Fa0/1 and NetworkB can be in the same subnet.
11 A network administrator plugs a new PC into a switch port. TheLEDfor that port changes to solid green. What statement best describesthecurrent status of the port?
There is a duplex mismatch error.
There is a link fault error. This port is unable to forward frames.
The port is operational and ready to transmit packets.
This port has been disabled by management and is unable to forward frames. The flash memory is busy.
12 Refer to the exhibit. Which three statements are true abouttheoutput of the show ip interface brief command? (Choose three.)
FastEthernet0/0 is functioning correctly.
The shutdown command has been applied on Serial0/0.
FastEthernet0/0 was configured by the startup-config at bootup.
Serial0/0 is experiencing a Layer 1 network problem.
FastEthernet0/1 is experiencing a Layer 2 network problem.
Because the port is down, Serial0/1 has an IP address that does not show in the output.
