8. Refer to the graphic. What configuration is incorrect in the network shown?
* The wired connection is the wrong type of cable.
* The Linksys integrated router does not support wireless.
* The host IP address is incorrect.
* The host subnet mask is incorrect.
* The host default gateway is incorrect.


9. 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 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.
* The power supply is the source of the problem.
* The ports are operational and are receiving traffic.

10. 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
* trial-and-error
* divide-and-conquer
* substitution

11. 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?
* The RJ-45 connectors are crimped onto the cable jacket.
* A crossover cable is being used.
* A straight-through cable is being used
* The connectors at both ends of the cable are RJ-45.



12. 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
* enabling MAC address filters
* using the default internal IP address
* using open authentication
* using DHCP to provide IP addresses


13. Which three settings must match on the client and access point for a wireless connection to occur? (Choose three.)
* antennae type
* encryption key
* MAC address filters
* SSID
* authentication
* MD5 checksum

14. Refer to the graphic. The wireless host cannot access the Internet, but the wired host can. What is the problem?
* The integrated router internal IP address is incorrect.
* The integrated router Internet IP address is incorrect.
* The host WEP key is incorrect.
* The host IP address is incorrect.
* The host subnet mask is incorrect.
* The host default gateway is incorrect.

15. When acting as a DHCP server, what three types of information can an ISR provide to a client? (Choose three.)
* MAC address
* default gateway
* physical address
* static IP address
* dynamic IP address
* DNS server address

16. 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 spare switches, routers, and other equipment available
* keeping a record of system upgrades and software versions

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

* The Linksys integrated router does not support wireless.
* 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.

18. 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 both devices have the same IP address.
* Ensure the correct cable is used.
* Ensure the SSID is the same on both devices.
* 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.

19. What two items could be checked to verify connectivity between the router and the ISP? (Choose two.)
* router status page
* wireless card settings
* local host operating system version
* connectivity status as indicated by LEDs
* router operating system version

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 several computers are added to the network
* at the end of the work week
* after major changes are implemented on the network

21. Typically, help desk personnel assist end users in which two tasks? (Choose two.)
* identifying when the problem occurred
* running a network baseline test
