Part 5.2

A user is experiencing slow network speeds on their desktop computer. Upon inspection, you notice the computer is connected using a Cat5 cable instead of a Cat6 cable. What is the most likely reason for the slow speeds?

• Cat5 cables are more prone to physical damage.

• Cat5 cables support lower maximum data rates than Cat6 cables.

• Cat5 cables are incompatible with most network devices.

• Cat5 cables are only used for telephone connections.

You are setting up a network and need to connect a computer to a switch located 120 meters away. Which issue are you most likely to encounter if you use a standard Ethernet cable?

• The cable will not physically fit into the port.

• The signal may degrade due to exceeding the recommended cable length.

• The cable will cause electromagnetic interference.

• The cable will provide power to the switch.

A network printer is not responding. You check the Ethernet cable and notice the connector clip is broken. What is the most appropriate action to restore connectivity?

• Replace the entire printer.

• Re-crimp or replace the Ethernet cable with a new connector.

• Restart the printer.

• Use a wireless connection instead.

During a network installation, you notice that cables are running parallel to fluorescent light fixtures. What type of problem could this cause, and how should you address it?

• It could cause signal interference; reroute the cables away from the lights.

• It could cause overheating; use thicker cables.

• It could cause physical damage; use armored cables.

• It could cause connector issues; use different connectors.

A user reports intermittent connectivity issues. Upon inspection, you see the network cable is pinched under a heavy filing cabinet. What is the best troubleshooting step?

• Ignore the issue if the cable still works.

• Replace the damaged cable and ensure it is routed safely.

• Reboot the computer.

• Update the network drivers.

You suspect a patch cable is faulty. Which tool should you use to verify the integrity of the cable?

• Multimeter

• Cable tester

• Screwdriver

• Loopback plug

A network device is not connecting to the network. You notice the cable is plugged into the wrong port on the patch panel. What should you do to resolve the issue?

• Replace the network device.

• Move the cable to the correct port on the patch panel.

• Shorten the cable.

• Change the IP address of the device.

You are troubleshooting a network issue and suspect crosstalk between cables. What is an effective way to reduce crosstalk?

• Use shielded twisted pair (STP) cables.

• Increase the cable length.

• Use thinner cables.

• Place cables closer together.

A user complains that their network connection drops whenever someone walks over the cable running across the floor. What is the most likely cause?

• The cable is too short.

• The cable is experiencing physical damage from being stepped on.

• The connector is incompatible.

• The cable is not shielded.

You need to verify if a newly installed fiber optic cable is transmitting data correctly. Which tool should you use for this task?

• Tone generator and probe

• Optical time-domain reflectometer (OTDR)

• Cable crimper

• RJ45 loopback adapter
