router and the ISP? (Choose two.)

router status page ***

Internet. What is the first troubleshooting step if the divide-and-conquer
method is being used?

Check the NIC, and then check the cabling.
Check the workstation TCP/IP configuration***.
Test all cables, and then test layer by layer up the OSI model.
Attempt to Telnet, and then test layer by layer down the OSI model.




3 What should a network administrator do first after receiving a call
from a user who cannot access the company web server?

Reboot the web server.
Replace the NIC of the computer.
Ask the user to log off and log on again.
Ask the user what URL has been typed and what error message
displays.***




4 A technician suspects that a Linksys integrated router is the source
of a network problem. While troubleshooting, the technician notices a
blinking green activity LED on some of the ports. What does this
indicate?

Self-diagnostics have not completed.
The power supply is the source of the problem.
The ports are operational and are receiving traffic.***
The ports are operational, but no traffic is flowing.
There are no cables plugged into those ISR ports.
The ports have cables plugged in, but they are not functional.




5

Refer to the graphic. The wireless host cannot access the Internet, but
the wired host can. What is the problem?

The host WEP key is incorrect.
The host IP address is incorrect.
The host subnet mask is incorrect.
The host default gateway is incorrect.
The integrated router internal IP address is incorrect.
The integrated router Internet IP address is incorrect.




6 Which ipconfig command requests IP configuration from a DHCP server?

ipconfig
ipconfig /all
ipconfig /renew ***

7 Which two troubleshooting techniques are suitable for both home
networks and large corporate networks? (Choose two.)

having a backup ISR
running network monitoring applications ***
documenting the troubleshooting process
keeping a record of system upgrades and software versions ***
keeping spare switches, routers, and other equipment available




8 Which two items should be added to the documentation following a
troubleshooting event? (Choose two.)

final resolution ***
repetitive measures
number of people involved in the problem
accurate current network infrastructure diagrams
results of successful and unsuccessful troubleshooting steps ***




9 Which troubleshooting method begins by examining cable connections
and wiring issues?

top-down
bottom-up ***
substitution
divide-and-conquer




10

Refer to the graphic. What configuration is incorrect in the network
shown?

The host IP address is incorrect.
The host subnet mask is incorrect.
The host default gateway is incorrect.
The wired connection is the wrong type of cable.
The Linksys integrated router does not support wireless.




11

Refer to the graphic. What configuration is incorrect in the network
shown?

The host IP address is incorrect.
The host subnet mask is incorrect.
The host default gateway is incorrect.
The wired connection is the wrong type of cable. ***
The Linksys integrated router does not support wireless.




12 When acting as a DHCP server, what three types of information can an
ISR provide to a client? (Choose three.)

physical address
MAC address
default gateway ***
static IP address
dynamic IP address ***
DNS server address ***




13 A technician is unsuccessful in establishing a console session
between a PC and a Linksys integrated router. Both devices have power, and a
cable is connected between them. Which two troubleshooting steps could
help to diagnose this problem? (Choose two.)

Ensure the correct cable is used. ***
Ensure the SSID is the same on both devices.
Ensure both devices have the same IP address.
Ensure both devices have different subnet masks.
Ensure the encryption type on both devices match.
Ensure the link status LED on the integrated router is lit. ***




14 A technician is troubleshooting a security breach on a new wireless
access point. Which three configuration settings make it easy for
hackers to gain access? (Choose three.)

configuring NAT
broadcasting the SSID ***
using open authentication ***
enabling MAC address filters
using the default internal IP address***
using DHCP to provide IP addresses




15 A PC is plugged into a switch and is unable to connect to the
network. The UTP cable is suspected. What could be the problem?

A straight-through cable is being used
The connectors at both ends of the cable are RJ-45.
The RJ-45 connectors are crimped onto the cable jacket.
A crossover cable is being used. ***

Businesses (Version 4.0)

16 What command is used to determine if a DNS server is providing name
resolution?

ipconfig
netstat
nslookup ***
tracert




17 Identify two physical-layer network problems. (Choose two.)

hardware failure***
software configuration
devices not able to ping
loose cable connections***
device driver configuration




18 Typically, help desk personnel assist end users in which two tasks?
(Choose two.)

identifying when the problem occurred***
determining if other users are currently logged into the computer
updating network diagrams and documentation
implementing the solution to the problem ***
running a network baseline test
determining the cost of fixing the problem




19 A customer called the cable company to report that the Internet
connection is unstable. After trying several configuration changes, the
technician decided to send the customer a new cable modem to try. What
troubleshooting technique does this represent?

top-down
bottom-up
substitution
trial-and-error ***
divide-and-conquer




20 Network baselines should be performed in which two situations?
(Choose two.)

after the network is installed and running optimally ***
after a virus outbreak is discovered on the network
after major changes are implemented on the network ***
after several computers are added to the network
at the end of the work week




21 Which three settings must match on the client and access point for a
wireless connection to occur? (Choose three.)

SSID ***
authentication ***
MD5 checksum
antennae type
encryption key ***
MAC address filters




22 What command is used to determine the location of delay for a packet
traversing the Internet?

23 How does remote-access software help in the troubleshooting process?

Remote access uses a live chat feature.
Users have to be present so that they can view LEDs and change cables
if necessary.
Diagnostics can be run without a technician being present at the
site***.
FAQs can be consulted more easily.
