Hardware and Network Troubleshooting 3

A technician is troubleshooting a computer configured for wired network connection that can't connect to the network. They verified that the cable is plugged in, but there are no lights lit on the network card. The computer could connect yesterday, and no other users report an issue. Which of the following are most likely to be causing this problem? (Choose two.)

• Faulty network cable.

• Faulty network card driver.

• Incorrect TCP/IP configuration.

• The cable is unplugged at the other end.

You are troubleshooting network connectivity issues in one section of the building. After a few hours, you come to the conclusion that the network cables in the wiring closet must be mislabeled. Which tool is most appropriate to test your theory?

• Multimeter

• Cable tester

• Punchdown tool

• Tone generator and probe

You have just installed a new HP LaserJet printer on your network. You've plugged it directly into a Cat 6a network cable. You try to install the printer on a client using the printer's IP address, but you are unable to connect. The printer is in Ready state. What should you do next?

• Double-check the printer's IP configuration information.

• Stop and restart the spooler service.

• Take the printer offline and bring it back online.

• Turn the printer off and back on to save the IP configuration information.

Your network has recently grown from 50 client computers to about 90. All workstations on the network are connected using Cat 6 or better cabling, and all network devices support at least 1 Gbps data transfers. Users have been reporting very slow network speeds since the expansion, and complaints are now coming more frequently. Which of the following actions is most likely to help resolve the issue?

• Add another hub to the network.

• Upgrade all the cabling to Cat 8.

• Upgrade the existing router to support 10 Gbps data transfers.

• Add another switch to the network.

Your junior IT administrator has identified a port on your Cisco switch that is changing between up and down repeatedly. What have they observed?

• Port flapping

• Port toggling

• Port flashing

• Port flagging

Users have been complaining that a network resource has intermittent connectivity. You've identified the problem; the switch port is flapping. The connected device is not EEE compliant, and users need it to be available. What should you do?

• Configure link flap prevention settings.

• Replace the offending device.

• Disable EEE on the switch.

• Disable EEE on the device.

A user calls you about a printer not working. The user is standing next to the printer while you are in the next building. What can the user do to be helpful in your diagnosing the problem?

• Turn the printer off and on.

• Read the printer error code.

• Remove the jammed paper.

• Check the network link light.

A user calls to report that they can't access the Internet or a corporate server. However, they are still able to print to a printer nearby. They have not received any error messages. Other users in the area are also unable to access the Internet. What is most likely the problem?

• IP address conflict

• Default gateway down

• Incorrect subnet mask

• Network card failure

A workstation is sending print jobs directly to a printer that has a stapler as a finishing option. When they retrieve the print job, the document is not stapled. Which of the following could be the problem? (Choose three.)

• The stapler is empty.

• The staples are in backward.

• A different printer driver is needed.

• The stapler is not enabled.

A message has appeared on the office copier/printer that says “Stapler Jam.” Which of the following are true? (Choose three.)

• The jam must be cleared before anything else is printed.

• Print jobs not involving the stapler may still work.

• This can be caused by trying to staple too many pages.

• The manufacturer documentation should be consulted for procedures to follow.
