You need to trace the route that a Cat 6 UTP cable takes through the ceiling and walls of your building. Which tool should you use?
Tone generator.A tone generator is used to trace a UTP cable through walls and ceilings. A tone generator is attached to one end of the cable. Then the probe is used to audibly trace the wire.
A multimeter is used to measure electrical voltage and resistance. A cable tester tests UTP cables for continuity and resistance. A loopback plug is used to test network communications by redirecting a signal from the transmit port on a device to the receive port on the same device.
A maintenance worker accidently nicks a bundle of network cables routed to multiple wall jacks in a conference room. Only one of the cable's wires are severed. A technician is tasked with replacing the cable.
Which of the following tools would the technician MOST likely use to identify which wall jack connects to the severed cable?
Tone generator and probe.A tone generator and probe can be used to identify the wall jack connected to the severed wire. The tone generator can be attached to the severed wire, and the probe will sound when it is brought close to the connected wall jack.
A multimeter measures voltage, current, and resistance on a wire.
A loopback plug can be plugged into a network adapter to test whether the NIC can send and receive properly.
A cable stripper is used to cut away the plastic jacket or coating from a network cable.
While investigating a network connectivity issue, a technician finds that the link light on a workstation is not lit, and there is no connectivity after replacing the patch cable with one that is known to be good. The wall jack is not labeled, and within the switch room, none of the cables or patch panel ports are labeled.
Tone generator.A tone generator can be used to identify which port in the patch panel connects to the wall jack. The technician could then investigate further by following the cable from the patch panel to the switch.
A cable tester might be used after the correct cable and patch panel port are identified.
A crimper is used to attach an RJ45 or RJ11 end to a twisted pair cable.
A punchdown tool may be needed later if the identified cable is not attached correctly to either the wall jack or the patch panel. If the cable is not identified, the cable can't be repaired.
While investigating a network connectivity issue, a technician finds that the link light on a workstation is not lit, and there is no connectivity after replacing the patch cable both between the workstation and the wall jack and between the patch panel and the switch with cables that are known to be good.
If the wall jack and patch panel ports are labeled correctly, which of the following tools would the technician MOST likely use next?
Cable testerA cable tester is the BEST choice for determining whether there are problems in the cable between the wall jack and the patch panel.
A tone generator is not needed, since the port on the patch panel that connects to the wall jack is already identified.
After you determine whether the cable is bad between the wall jack and the patch panel, you may need a punchdown tool to repair or replace the cable connectors.
A crimper is used to attach an RJ45 or RJ11 end to a twisted pair cable.
Which of the following BEST describes the purpose for which loopback plugs are used?
Testing ports by returning output signals as input.Loopback plugs are used to test ports by returning output signals as input. Use a loopback plug to test the functionality of serial ports or networking ports.
Null modem cables are used to connect computers using their serial ports without the need for a modem and phone line connection. A 3-prong holder is a tweezers-like tool with three prongs used for grabbing and lifting small objects. An IC extractor is a tweezer-like tool, usually spring-loaded in the open position, used to remove integrated circuit chips.
A printer is behaving erratically, and you suspect a faulty parallel port. Which tool can you use to test the parallel port?
Loopback plug. A loopback plug allows an output signal to be returned as input. Loopback plugs are used to test serial and parallel ports.
A cable tester verifies that a network can carry a signal from one end to the other, and that all wires within the connector are in their correct positions. A multimeter measures electrical properties such as voltage, amps, and resistance. An ammeter is an instrument that measures the flow of electric current in a circuit.
Your workstation is unable to communicate with any other computer on the network. Which of the following tools should you use to test the network card's abilities to send and receive signals?
Loopback plugUse a loopback plug to test the network card's ability to send and receive signals. Pinging the local host (ping 127.0.0.1) tests the TCP/IP protocol stack, but does not actually send signals out the network card. A cable tester tests continuity of all wires in a cable and ensures that wires are connected appropriately in the plugs. Use a multimeter and an ohmmeter to test the electrical properties of cables and signals.
Which of the following tools can help prevent damage when working with computer components?
Antistatic pad and wrist strap.An antistatic pad provides an insulated covering to prevent static electricity from moving between objects and damaging computer components. When working with computer components, use a wrist strap connected to the antistatic pad and connect the pad to a ground.
A tone generator and probe is used to trace a wire from one location to another, especially through the walls of a building.
An IC insertion and extraction tool is used to add or remove integrated circuit chips that are used on motherboards and some computer components.
A three-pronged parts retriever is used to grasp and retrieve small parts that have fallen into areas that are difficult to reach.
A technician is asked to repair a broken Ethernet jack in a conference room. Which of the following tools would the technician use when repairing the wall jack?
Punchdown tool
A technician is making RJ-45 patch cables. Which of the following tools will the technician use to terminate the cable ends?
Crimper
A contractor has removed a wall jack and thrown it away. There is no longer a line number on the network cable. A technician attaches a far end connector and proceeds to several wiring closets to find the patch panel location of the cable. Which of the following tools will the technician need for this job?Toner probeA network administrator is planning to connect the network of two buildings together with a Category 5e cable. Ten Ethernet cables have been run from a wiring closet, through a conduit, and into a wiring closet on the other side. The network administrator needs to identify the ends of the cables so they can be properly terminated on each side. Which of the following should be used to complete this task?tone generatorA printer is behaving erratically, and you suspect a faulty parallel port. Which tool can you use to test the parallel port?A loopback plug allows an output signal to be returned as input. Loopback plugs are used to test serial and parallel ports. A cable tester verifies that a network can carry a signal from one end to the other, and that all wires within the connector are in their correct positions. A multimeter measures electrical properties such as voltage, amps, and resistance. An ammeter is an instrument that measures the flow of electric current in a circuit.After removing the printed paper from your laser printer, the toner smudges and can be wiped off in places.Fuser rollersBecause the fuser rollers heat and press the entire paper, dirty fuser rollers are the most likely problem. The other components do not touch the paper directly.fter receiving several complaints from the employees in your company, you start to troubleshoot a laser printer. After a short while, you have concluded that the most probable cause is a dirty drum. Which of the following is the MOST logical reasons for this conclusion?Spots at regular intervals on the page typically indicate a dirty drum. Blank pages are caused by no toner or a faulty primary corona. Ghost images are caused by a faulty scraper blade or discharge lamp. Garbage characters are caused by using the wrong print driver.You work for a company based in Phoenix, Arizona, which is a very hot and dry area. Several people in the research department have reported that even though their files are printing to their laser printer correctly, a much lighter copy of the same text also prints within 2 to 3 cm of the original text. Which of the following would MOST likely fix this type of ghosting image?Replace the imaging drum, as it is probably at end of life.When ghost images are within 2 to 3 cm of the original image, this is an indication that the ghosting is caused by the imaging drum. When a drum unit comes to the end of its useable life cycle, it may not discharge properly, leaving behind faint traces of the previous printing job. An imaging drum can also become defective and discharge incorrectly between print runs, also causing ghosting to occur. In either case, the best solution it to replace the imaging drum. Using heavier weight paper will not fix ghosting images. If the drum is bad, the ghosting will still be present regardless of the weight of paper. Heavier weight paper can actually cause ghosting to occur if the ghosting issue is the result of a faulty fuser unit. If this printer was in a high-humidity environment, it is possible that the toner may clump together inside the cartridge. When this happens, the toner powder does not get distributed evenly when printing, which can lead to ghost images on the page. However, Arizona is a very dry environment, so this probably isn't the issue.Which of the following BEST describes the purpose for which loopback plugs are used?Testing ports by returning output signals as input.Loopback plugs are used to test ports by returning output signals as input.
