1	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.

2	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

3	Only one workstation on a particular network cannot reach the 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.

4	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

5	Identify two physical-layer network problems. (Choose two.) hardware failure software configuration devices not able to ping loose cable connections device driver configuration

6	Which ipconfig command requests IP configuration from a DHCP server? ipconfig ipconfig /all ipconfig /renew ipconfig /release

7	What command is used to determine the location of delay for a packet traversing the Internet? ipconfig netstat nslookup ping tracert

8	What command is used to determine if a DNS server is providing name resolution? ipconfig netstat nslookup tracert

9	Which troubleshooting method begins by examining cable connections and wiring issues? top-down bottom-up substitution divide-and-conquer

10

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.

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? 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.

12	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.

13	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

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	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.

16	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.

17	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

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

19

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.

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	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

22	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.

23	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
